When ARM Trusted Firmware is built with EL3_EXCEPTION_HANDLING=1,
EL3 interrupts (INTR_TYPE_EL3) will always preempt both Non-secure and
secure execution.
The interrupt management framework currently treats EL3 interrupt
routing as valid. For the above reason, this patch makes them invalid
when EL3_EXCEPTION_HANDLING is in effect.

This patch expands the weak stubs for the plat_crash_console_xxx
functions in common platform code to use the new console API for crash
output. This should make crash console output "just work" for most cases
without the need for the platform to explicitly set up a crash console.
For cases where the normal console framework doesn't work (e.g. very
early crashes, before the platform can register any consoles), platforms
are still able to override the functions just like before.
This feature requires the MULTI_CONSOLE_API compile-time flag to work.
For builds which don't have it set, this patch has no practical effect.

A new platform macro `PLAT_AMU_GROUP1_COUNTERS_MASK` controls which

If the platform does not define this mask, no group 1 counters are

Invalidate the Branch Target Buffer (BTB) on entry to EL3 by disabling
and enabling the MMU. To achieve this without performing any branch
instruction, a per-cpu vbar is installed which executes the workaround
and then branches off to the corresponding vector entry in the main
vector table. A side effect of this change is that the main vbar is
configured before any reset handling. This is to allow the per-cpu
reset function to override the vbar setting.
This workaround is enabled by default on the affected CPUs.

This patch adds a new build option, ENABLE_SVE_FOR_NS, which when set
to one EL3 will check to see if the Scalable Vector Extension (SVE) is
implemented when entering and exiting the Non-secure world.
If SVE is implemented, EL3 will do the following:
- Entry to Non-secure world: SIMD, FP and SVE functionality is enabled.
- Exit from Non-secure world: SIMD, FP and SVE functionality is
disabled. As SIMD and FP registers are part of the SVE Z-registers
then any use of SIMD / FP functionality would corrupt the SVE
registers.
The build option default is 1. The SVE functionality is only supported
on AArch64 and so the build option is set to zero when the target
archiecture is AArch32.
This build option is not compatible with the CTX_INCLUDE_FPREGS - an
assert will be raised on platforms where SVE is implemented and both
ENABLE_SVE_FOR_NS and CTX_INCLUDE_FPREGS are set to 1.
Also note this change prevents secure world use of FP&SIMD registers on
SVE-enabled platforms. Existing Secure-EL1 Payloads will not work on
such platforms unless ENABLE_SVE_FOR_NS is set to 0.
Additionally, on the first entry into the Non-secure world the SVE
functionality is enabled and the SVE Z-register length is set to the
maximum size allowed by the architecture. This includes the use case
where EL2 is implemented but not used.

This patch fixes a couple of issues for AArch32 builds on ARM reference
platforms :
1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
the BL31 memory is empty when built for AArch32. Hence this patch allocates
BL32 to the memory region occupied by BL31 for AArch32 builds.
As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
be used to control the load address of BL32 in AArch32 mode which was
never the intention of the macro anyway.
2. A static assert is added to sp_min linker script to check that the progbits
are within the bounds expected when overlaid with other images.
3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
involved when building Juno for AArch32 mode, the build option SPD needed to
specifed. This patch corrects this and also updates the documentation in the
user-guide.
4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
a result the previous assumption that BL31 must be always present is removed
and the certificates for BL31 is only generated if `NEED_BL31` is defined.

The FPEXC32_EL2 register controls SIMD and FP functionality when the
lower ELs are executing in AArch32 mode. It is architecturally mapped
to AArch32 system register FPEXC.
This patch removes FPEXC32_EL2 register from the System Register context
and adds it to the floating-point context. EL3 only saves / restores the
floating-point context if the build option CTX_INCLUDE_FPREGS is set to 1.
The rationale for this change is that if the Secure world is using FP
functionality and EL3 is not managing the FP context, then the Secure
world will save / restore the appropriate FP registers.
NOTE - this is a break in behaviour in the unlikely case that
CTX_INCLUDE_FPREGS is set to 0 and the platform contains an AArch32
Secure Payload that modifies FPEXC, but does not save and restore
this register

EHF is a framework that allows dispatching of EL3 interrupts to their
respective handlers in EL3.
This framework facilitates the firmware-first error handling policy in
which asynchronous exceptions may be routed to EL3. Such exceptions may
be handed over to respective exception handlers. Individual handlers
might further delegate exception handling to lower ELs.
The framework associates the delegated execution to lower ELs with a
priority value. For interrupts, this corresponds to the priorities
programmed in GIC; for other types of exceptions, viz. SErrors or
Synchronous External Aborts, individual dispatchers shall explicitly
associate delegation to a secure priority. In order to prevent lower
priority interrupts from preempting higher priority execution, the
framework provides helpers to control preemption by virtue of
programming Priority Mask register in the interrupt controller.
This commit allows for handling interrupts targeted at EL3. Exception
handlers own interrupts by assigning them a range of secure priorities,
and registering handlers for each priority range it owns.
Support for exception handling in BL31 image is enabled by setting the
build option EL3_EXCEPTION_HANDLING=1.
Documentation to follow.
NOTE: The framework assumes the priority scheme supported by platform
interrupt controller is compliant with that of ARM GIC architecture (v2
or later).

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.

The current implementation of the memory mapping API favours mapping
memory regions using the biggest possible block size in order to
reduce the number of translation tables needed.
In some cases, this behaviour might not be desirable. When translation
tables are edited at run-time, coarse-grain mappings like that might
need splitting into finer-grain tables. This operation has a
performance cost.
The MAP_REGION2() macro allows to specify the granularity of
translation tables used for the initial mapping of a memory region.
This might increase performance for memory regions that are likely to
be edited in the future, at the expense of a potentially increased
memory footprint.
The Translation Tables Library Design Guide has been updated to
explain the use case for this macro. Also added a few intermediate
titles to make the guide easier to digest.

This patch does the required changes to enable CSS platforms
to build and use the SDS framework. Since SDS is always coupled with
SCMI protocol, the preexisting SCMI build flag is now renamed to
`CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on
CSS platforms. Also some of the workarounds applied for SCMI are
now removed with SDS in place.

This patch enables choice of RSA version at run time to be used for
generating signatures by the cert_tool. The RSA PSS as defined in
PKCS#1 v2.1 becomes the default version and this patch enables to specify
the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
-a option. Also, the build option `KEY_ALG` can be used to pass this
option from the build system. Please note that RSA PSS is mandated
by Trusted Board Boot requirements (TBBR) and legacy RSA support is
being added for compatibility reasons.

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

The internal synchronisation timings of the FVP model version
11.0 build 11.0.34 and version 8.5 build 0.8.5202 has been
changed compared to older version of the models.
This change may have an impact on how the model behaves depending
on the workload being run on the model. For example test failures
have been seen where the primary core has powered on a secondary
core but was then starved of host CPU time and so was not able to
update power status, resulting a test failure due to an incorrect
status. This, or similar behaviour, is not to be expected from
real hardware platforms.
This patch adds a usage note on how to launch these models so
that internal synchronisation timing matches that of the older
version of the models, specifically adding the -Q 100 option.

tables so that multiple PEs in the same Inner Shareable domain can use
the same translation table entries for a given stage of translation in
a particular translation regime. This only takes effect when ARM
Trusted Firmware is built with ARM_ARCH_MINOR >= 2.
ARM Trusted Firmware Design has been updated to include a description

specified at build time. The device constraints can be determined at run
time from its ID registers, obviating the need for specifying them
ahead.
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

ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:
- The MT bit set;
- Affinity levels pertaining to cluster and CPUs occupy one level
higher than in a single-threaded implementation, and the lowest
affinity level pertains to hardware threads. MPIDR affinity level
fields essentially appear shifted to left than otherwise.
The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.
To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.
An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

This patch adds an early suspend handler, that executes with
SMP and data cache enabled. This handler allows platforms to
perform any early actions during the CPU suspend entry sequence.
This handler is optional and platforms can choose to implement it
depending on their needs. The `pwr_domain_suspend` handler still
exists and platforms can keep on using it without any side effects.

At the moment, various parts of the Trusted Firmware code assume
that the granule size used is 4 KB. For example, the linker scripts
enforce 4 KB alignment restrictions on some sections.
However, the ARMv8-A architecture allows 16 KB and 64 KB granule
sizes as well. Some other parts of the TF code, particularly the
architectural code and definitions, have been implemented with
this in mind and cater for all 3 cases.
This discrepancy creates some confusion as to what is effectively
supported in TF. This patch adds some code comments and clarification
in the documentation to make this limitation clearer.

This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:
* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.
* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.
* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.
The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.
This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.
This patch also corrects the following typos:
"NASCR definitions" -> "NSACR definitions"
