*All* UART drivers in TF-A are storing their base address as a uintptr_t
pointer in the first location of the UART specific driver data.
Since the base address is a pretty natural and generic data item, we
should integrate this into the generic console_t structure.
That will not only allow to remove a lot of seemingly UART specific data
structures, but also enables to simplify runtime choices between different
UARTs, since they can share the same pointer.
This patch just adds the new member, the existing data structures will
be handled on a per-UART base in follow-up patches.

On systems that have multiple platform components that can interpret the
SCMI messages, there is a need to support multiple SCMI channels (one
each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

In order to access MG SRAM, the amb bridge needs to be configured which is
done in bl2 platform init.
For MG CM3, the image is only loaded to its SRAM and the CM3 itself is
left in reset. It is because the next stage bootloader (e.g. u-boot)
will trigger action which will take it out of reset when needed. This
can happen e.g. when appropriate device-tree setup (which has enabled
802.3 auto-neg) will be chosen. In other cases the MG CM3 should not be
running.

The raw NAND framework supports SLC NAND devices.
It introduces a new high level interface (io_mtd) that
defines operations a driver can register to the NAND framework.
This interface will fill in the io_mtd device specification:
- device_size
- erase_size
that could be used by the io_storage interface.
NAND core source file integrates the standard read loop that
performs NAND device read operations using a skip bad block strategy.
A platform buffer must be defined in case of unaligned
data. This buffer must fit to the maximum device page size
defined by PLATFORM_MTD_MAX_PAGE_SIZE.
The raw_nand.c source file embeds the specific NAND operations
to read data.
The read command is a raw page read without any ECC correction.
This can be overridden by a low level driver.
No generic support for write or erase command or software
ECC correction.
NAND ONFI detection is available and can be enabled using
NAND_ONFI_DETECT=1.
For non-ONFI NAND management, platform can define required
information.

The SCU connects one to four Cortex-A5/Cortex-A9 processors
to the memory system through the AXI interfaces.
The SCU functions are to:
- maintain data cache coherency between the Cortex-A5/Cortex-A9
processors
- initiate L2 AXI memory accesses
- arbitrate between Cortex-A5/Cortex-A9 processors requesting
L2 accesses
- manage ACP accesses.
Snoop Control Unit will enable to snoop on other CPUs caches.
This is very important when it comes to synchronizing data between
CPUs. As an example, there is a high chance that data might be
cache'd and other CPUs can't see the change. In such cases,
if snoop control unit is enabled, data is synchoronized immediately
between CPUs and the changes are visible to other CPUs.
This driver provides functionality to enable SCU as well as enabling
user to know the following
- number of CPUs present
- is a particular CPU operating in SMP mode or AMP mode
- data cache size of a particular CPU
- does SCU has ACP port
- is L2CPRESENT

On some platforms the UART might have already been initialised, for
instance by firmware running before TF-A or by a separate management
processor. In this case it would not be need to initialise it again
(doing so could create spurious characters). But more importantly this
saves us from knowing the right baudrate and the right base clock rate
for the UART. This can lead to more robust and versatile firmware builds.
Allow to skip the 16550 UART initialisation and baud rate divisor
programming, by interpreting an input clock rate of "0" to signify this
case. This will just skip the call to console_16550_core_init, but still
will register the console properly.
Users should just pass 0 as the second parameter, the baudrate (third
parameter) will then be ignored as well.
Fix copy & paste typos in comments for the console_16550_register()
function on the way.

Previously, the A64/H5 and H6 platforms' PMIC setup code was entirely
independent. However, some H6 boards also need early regulator setup.
Most of the register interface and all of the device tree traversal code
can be reused between the AXP803 and AXP805. The main difference is the
hardware bus interface, so that part is left to the platforms. The
remainder is moved into a driver.
I factored out the bits that were obviously specific to the AXP803;
additional changes for compatibility with other PMICs can be made as
needed.
The only functional change is that rsb_init() now checks the PMIC's chip
ID register against the expected value. This was already being done in
the H6 version of the code.

This patch adds a new include/export/ directory meant for inclusion in
third-party code. This is useful for cases where third-party code needs
to interact with TF-A interfaces and data structures (such as a custom
BL2-implementation like coreboot handing off to BL31). Directly
including headers from the TF-A repository avoids having to duplicate
all these definitions (and risk them going stale), but with the current
header structure this is not possible because handoff API definitions
are too deeply intertwined with other TF code/headers and chain-include
other headers that will not be available in the other environment.
The new approach aims to solve this by separating only the parts that
are really needed into these special headers that are self-contained and
will not chain-include other (non-export) headers. TF-A code should
never include them directly but should instead always include the
respective wrapper header, which will include the required prerequisites
(like <stdint.h>) before including the export header. Third-party code
can include the export headers via its own wrappers that make sure the
necessary definitions are available in whatever way that environment can
provide them.

When Trusted Board Boot is enabled, we need to specify the Chain of
Trust (CoT) of the BL1 and BL2 images. A CoT consists of an array
of image descriptors. The authentication module assumes that each
image descriptor in this array is indexed by its unique image
identifier. For example, the Trusted Boot Firmware Certificate has to
be at index [TRUSTED_BOOT_FW_CERT_ID].
Unique image identifiers may not necessarily be consecutive. Also,
a given BL image might not use all image descriptors. For example, BL1
does not need any of the descriptors related to BL31. As a result, the
CoT array might contain holes, which unnecessarily takes up space in
the BL binary.
Using pointers to auth_img_desc_t structs (rather than structs
themselves) means these unused elements only use 1 pointer worth of

the code which accesses this array to reflect the change to pointers.
Image descriptors not needed in BL1 or BL2 respectively are also
ifdef'd out in this patch. For example, verifying the BL31 image is
the responsibility of BL2 so BL1 does not need any of the data

There are some issues with synopsys MMC driver:
- CMD8 should not expect data (for SD)
- ACMD51 should expect data (Send SCR for SD)
- dw_prepare should not dictate size to be MMC_BLOCK_SIZE, block size is
now handled in the dw_prepare function
- after the CMD completes, when doing dw_read, we need to invalidate cache
and wait for the data transfer to complete
- Need to set FIFO threshold, otherwise DMA might never get the interrupt
to read or write

- scr cannot be local as this will cause cache issue when invalidating

This commit improves the SDHost driver for RPi3 as following:
* Unblock MMC_CMD(17). Using MMC_CMD(17) is more efficient on
block reading.
* In some low probability that SEND_OP_COND might results CRC7
error. We can consider that the command runs correctly. We don't
need to retry this command so removing the code for retry.
* Using MMC_BUS_WIDTH_1 as MMC default value to improve the stability.
* Increase the clock to 50Mhz in data mode to speed up the io.
* Change the pull resistors configuration to gain more stability.

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

similarities with I2C. It sports a much higher bus frequency, though,
(typically 3 MHz) and requires much less handholding for the typical

On most A64 boards this bus is used to connect the PMIC to the SoC.

The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.
Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform
specific, optimised implemenetation.

This change is largely based on existing eMMC framework by Haojian Zhuang
(@hzhuang1).
The MMC framework supports both eMMC and SD card devices. It was
written as a new framework since breaking few eMMC framework APIs.
At card probe and after the reset to idle command (CMD0), a Send
Interface Condition Command is sent (CMD8) to distinguish between
eMMC and SD card devices. eMMC devices go through the same
sequence as in the former eMMC framework. Else the framework
uses commands dedicated to SD-cards for init or frequency switch.
A structure is created to share info with the driver. It stores:
- the MMC type (eMMC, SD or SD HC)
- the device size
- the max frequency supported by the device
- the block size: 512 for eMMC and SD-HC and read from CSD
structure for older SD-cards
Restriction to align buffers on block size has been removed.
Cache maintenance was removed and is expected to be done in the platform
or device driver.
The MMC framework includes some MISRA compliance coding style
maybe not yet ported in the existing eMMC framework.

The old API is deprecated and will eventually be removed.
Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.
The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.
Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.
The size reserved for BL2 has been increased.

In the multi console driver, allowing to register the same console more
than once may result in an infinte loop when putc is called.
If, for example, a boot message is trying to be printed, but the
consoles in the loop in the linked list are runtime consoles, putc will
iterate forever looking for a console that can print boot messages (or
a NULL pointer that will never come).
This loop in the linked list can occur after restoring the system from a
system suspend. The boot console is registered during the cold boot in
BL31, but the runtime console is registered even in the warm boot path.
Consoles are always added to the start of the linked list when they are
registered, so this it what should happen if they were actually
different structures:
console_list -> NULL
console_list -> BOOT -> NULL
console_list -> RUNTIME -> BOOT -> NULL
console_list -> RUNTIME -> RUNTIME -> BOOT -> NULL
In practice, the two runtime consoles are the same one, so they create
this loop:
console_list -> RUNTIME -. X -> BOOT -> NULL
^ |
`----'
This patch adds an assertion to detect this problem. The assertion will
fail whenever the same structure tries to be registered while being on
the list.
In order to assert this, console_is_registered() has been implemented.
It returns 1 if the specified console is registered, 0 if not.

This bypasses the MULTI_CONSOLE_API for the crash console (UART1), but

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.
This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.
For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.
This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.
Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

This patch overhauls the console API to allow for multiple console
instances of different drivers that are active at the same time. Instead
of binding to well-known function names (like console_core_init),
consoles now provide a register function (e.g. console_16550_register())
that will hook them into the list of active consoles. All console
operations will be dispatched to all consoles currently in the list.
The new API will be selected by the build-time option MULTI_CONSOLE_API,
which defaults to ${ERROR_DEPRECATED} for now. The old console API code
will be retained to stay backwards-compatible to older platforms, but
should no longer be used for any newly added platforms and can hopefully
be removed at some point in the future.
The new console API is intended to be used for both normal (bootup) and
crash use cases, freeing platforms of the need to set up the crash
console separately. Consoles can be individually configured to be active
active at boot (until first handoff to EL2), at runtime (after first
handoff to EL2), and/or after a crash. Console drivers should set a sane
default upon registration that can be overridden with the
console_set_scope() call. Code to hook up the crash reporting mechanism
to this framework will be added with a later patch.
This patch only affects AArch64, but the new API could easily be ported
to AArch32 as well if desired.

On GICv3 systems, as a side effect of adding provision to handle EL3
interrupts (unconditionally routing FIQs to EL3), pending Non-secure
interrupts (signalled as FIQs) may preempt execution in lower Secure ELs
[1]. This will inadvertently disrupt the semantics of Fast SMC
(previously called Atomic SMC) calls.
To retain semantics of Fast SMCs, the GIC PMR must be programmed to
prevent Non-secure interrupts from preempting Secure execution. To that
effect, two new functions in the Exception Handling Framework subscribe
to events introduced in an earlier commit:
- Upon 'cm_exited_normal_world', the Non-secure PMR is stashed, and
the PMR is programmed to the highest Non-secure interrupt priority.
- Upon 'cm_entering_normal_world', the previously stashed Non-secure
PMR is restored.
The above sequence however prevents Yielding SMCs from being preempted
by Non-secure interrupts as intended. To facilitate this, the public API
exc_allow_ns_preemption() is introduced that programs the PMR to the
original Non-secure PMR value. Another API
exc_is_ns_preemption_allowed() is also introduced to check if
exc_allow_ns_preemption() had been called previously.
API documentation to follow.
[1] On GICv2 systems, this isn't a problem as, unlike GICv3, pending NS
IRQs during Secure execution are signalled as IRQs, which aren't
routed to EL3.

An earlier patch added provision for the platform to provide secure

This patch defines macros that enumerate interrupt properties in the
same fashion, and points the driver driver data to a list of interrupt

deprecated interrupt list definitions are however retained to support
legacy builds.
Configuration applied to individual interrupts remain unchanged, so no
runtime behaviour change expected.

The GIC driver initialization currently allows an array of interrupts to
be configured as secure. Future use cases would require more interrupt
configuration other than just security, such as priority.
This patch introduces a new interrupt property array as part of both
GICv2 and GICv3 driver data. The platform can populate the array with
interrupt numbers and respective properties. The corresponding driver
initialization iterates through the array, and applies interrupt
configuration as required.
This capability, and the current way of supplying array (or arrays, in
case of GICv3) of secure interrupts, are however mutually exclusive.
Henceforth, the platform should supply either:
- A list of interrupts to be mapped as secure (the current way).
Platforms that do this will continue working as they were. With this
patch, this scheme is deprecated.
- A list of interrupt properties (properties include interrupt group).
Individual interrupt properties are specified via. descriptors of
type 'interrupt_prop_desc_t', which can be populated with the macro
INTR_PROP_DESC().
A run time assert checks that the platform doesn't specify both.
Henceforth the old scheme of providing list of secure interrupts is
deprecated. When built with ERROR_DEPRECATED=1, GIC drivers will require
that the interrupt properties are supplied instead of an array of secure
interrupts.
Add a section to firmware design about configuring secure interrupts.

This patch adds functions to save and restore GICv3 ITS registers during
system suspend. Please note that the power management of GIC ITS is
implementation defined. These functions only implements the
architectural part of the ITS power management and they do not restore
memory structures or register content required to support ITS. Even if
the ITS implementation stores structures in memory, an implementation
defined power down sequence is likely to be required to flush some
internal ITS caches to memory. If such implementation defined sequence
is not followed, the platform must ensure that the ITS is not power
gated during system suspend.

During system suspend, the GICv3 Distributor and Redistributor context
can be lost due to power gating of the system power domain. This means
that the GICv3 context needs to be saved prior to system suspend and
restored on wakeup. Currently the consensus is that the Firmware should
be in charge of this. See tf-issues#464 for more details.
This patch introduces helper APIs in the GICv3 driver to save and
restore the Distributor and Redistributor contexts. The GICv3 ITS
context is not considered in this patch because the specification says
that the details of ITS power management is implementation-defined.
These APIs are expected to be appropriately invoked by the platform
layer during system suspend.

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in

the Coding Guidelines. This patch changes all `UL` occurrences to `U`
or `ULL` depending on the context so that the size of the constant is
clear.
This problem affected the macro `BIT(nr)`. As long as this macro is used
to fill fields of registers, that's not a problem, since all registers
are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
macro is used to fill the fields of a 64-bit integer, it won't be able
to set the upper 32 bits in AArch32.
By changing the type of this macro to `unsigned long long` the behaviour
is always the same regardless of the architecture, as this type is
64-bit wide in both cases.

This patch adds changes to identify and validate CCI at run time. Some
global variables are renamed to be in line with the rest of the code
base.
The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is
updated.

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions in order to retain header groupings,
minimise changes to imported headers, and where there are headers within
the #if and #ifndef statements.

This patch adds header files with required declarations and
macro definitions to enable integration with CryptoCell SBROM
version `CC712 – Release 1.0.0.1061`. These headers enable ARM
Trusted Firmware to build and link with CryptoCell SBROM
library.

This patch adds support for RSASSA-PSS Signature Algorithm for
X509 certificates in mbedtls crypto driver. Now the driver supports
RSA PKCS2_1 standard as mandated by TBBR.
NOTE: With this patch, the PKCS1_5 standard compliant RSA signature
is deprecated.

If UFS device is initialized, we could just make it out of
hibernation by UFS_FLAGS_SKIPINIT. And vendor's dirver is always
focus on PHY setting. We could use UFS driver directly if it
exits from hibernation.
There're eight LUNs in UFS device. The UFS driver only provides
the read/write API with LUN. User could define his own read/write
since user may want to access different LUNs.

The Trusted Firmware uses a subset of the APIs provided by mbed TLS.
This subset internally uses `snprintf`, but the only format specifier
used is '%d', which is supported by `tf_snprintf`.
This patch makes mbed TLS use `tf_snprintf` instead of `snprintf`,
saving 3 KB in both debug and release builds when TBBR is enabled.

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.
But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

This function ensures that console output is flushed, for example
before shutting down or use by another component
In line with other console APIs, console_flush() wraps
console_core_flush().
Also implement console_core_flush() for PL011.

These macros are not part of mbed TLS so they should not be prefixed
with `MBEDTLS_` to avoid potential collision in the future. Use the
`TBBR_` suffix to highlight that they only used in TF.
`MBEDTLS_KEY_ALG` was not modified because that is documented and used
by platforms to select the key algorithm.

tbz check for RDR status is to check for a bit being zero.
Unfortunately, we are using a mask rather than the bit position.
Further as per http://www.ti.com/lit/ds/symlink/pc16550d.pdf (page 17),
LSR register bit 0 is Data ready status (RDR), not bit position 2.
Update the same to match the specification.

Some GICv3 implementations have provision for power management
operations at Redistributor level. This patch introduces and provides
place-holders for Redistributor power management. The default
implementations are empty stubs, but are weakly bound so as to enable
implementation-specific drivers to override them.

C99 restricts bitfields type is signed and unsigned integer or _Bool.
See section 6.7.2.1 Structure and union specifiers.
"A bit-field shall have a type that is a qualified or unqualified version
of _Bool, signed int, unsigned int, or some other implementation-defined type."
Since the compiler packs bitfields anyways, actual data layout in the structure is unaffected.
