On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently
32-bit values (because they are suffixed with UL and the value
0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.
This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.

There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.
This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.
The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.
This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).

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.

The ARM_INSTANTIATE_LOCK macro defines a lock meant to be further
manipulated using the arm_lock_init/get/release() macros. It has 2
variants, depending on the BL image it is compiled for. One version
defines the lock variable with internal linkage whereas the other one,
with external linkage.
Code that uses these macros is not compliant with MISRA rule 8.4 because
when using the external linkage version, there is no visible declaration

This patch defines the arm_lock variable with internal linkage in both

Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase
frame of the system timer. ARM ARM states that "The instance of
the register in the CNTCTLBase frame must be programmed with this
value as part of system initialization."
The psci_arch_setup() updates the CNTFRQ system register but
according to the ARM ARM, this instance of the register is
independent of the memory mapped instance. This is only an issue
for Normal world software which relies on the memory mapped
instance rather than the system register one.
This patch resolves the issue for ARM platforms.
The patch also solves a related issue on Juno, wherein
CNTBaseN.CNTFRQ can be written and does not reflect the value of
the register in CNTCTLBase frame. Hence this patch additionally

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.

The translation tables allocated for the Secure Partition do not need
to be treated as a special case. They can be put amongst the other
tables mapping BL31's general purpose memory. They will be mapped with
the same attributes as them, which is fine.
The explicit alignment constraint in BL31's linker script to pad the
last page of memory allocated to the Secure Partition's translation
tables is useless too, as page tables are per se pages, thus their
end address is naturally aligned on a page-boundary.
In fact, this patch does not change the existing behaviour. Since
patch 22282bb68a ("SPM: Move all SP-related info to SP context
struct"), the secure_partition.c file has been renamed into sp_xlat.c
but the linker script has not been properly updated. As a result, the
SP translation tables are not specifically put at the start of the
xlat_table linker section, the __SP_IMAGE_XLAT_TABLES_START__/_END__
symbols have the same value, the size of the resulting mmap_region
covering these xlat tables is 0 and so it is ignored.

The patch changes the layout of BL images in memory to enable
more efficient use of available space. Previously BL31 was loaded
with the expectation that BL2 memory would be reclaimed by BL32
loaded in SRAM. But with increasing memory requirements in the
firmware, we can no longer fit BL32 in SRAM anymore which means the
BL2 memory is not reclaimed by any runtime image. Positioning BL2
below BL1-RW and above BL31 means that the BL31 NOBITS can be
overlaid on BL2 and BL1-RW.
This patch also propogates the same memory layout to BL32 for AArch32
mode. The reset addresses for the following configurations are also
changed :
* When RESET_TO_SP_MIN=1 for BL32 in AArch32 mode
* When BL2_AT_EL3=1 for BL2
The restriction on BL31 to be only in DRAM when SPM is enabled
is now removed with this change. The update to the firmware design
guide for the BL memory layout is done in the following patch.

and ARM_SHARED_RAM. This memory was typically used for BL32 when
ARM_TSP_RAM_LOCATION=tsram but since we cannot fit BL32 in that
space anymore, it should be safe to use this memory for these configs.
There is also a runtime check in arm_bl2_dyn_cfg_init() which ensures
that this overlap doesn't happen.
The previous arm_dyn_get_hwconfig_info() is modified to accept configs
other than hw_config and hence renamed to arm_dyn_get_config_load_info().
The patch also corrects the definition of ARM_TB_FW_CONFIG_LIMIT to be
BL2_BASE.

This patch adds capability to FVP to disable authentication dynamically
via the `disable_auth` property in TB_FW_CONFIG. Both BL1 and BL2 parses
the TB_FW_CONFIG for the `disable_auth` property and invokes the
`load_dyn_disable_auth()` API to disable authentication if the
property is set to 1. The DYN_DISABLE_AUTH is enabled by default for
FVP as it is a development platform. Note that the TB_FW_CONFIG has to
be authenticated by BL1 irrespective of these settings.
The arm_bl2_dyn_cfg_init() is now earlier in bl2_plat_preload_setup()
rather than in bl2_platform_setup() as we need to get the value of
`disable_auth` property prior to authentication of any image by BL2.

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 of BL31 has been increased in builds with SPM.

At present, any External Abort routed to EL3 is reported as an unhandled
exception and cause a panic. This patch enables ARM Trusted Firmware to
handle External Aborts routed to EL3.
With this patch, when an External Abort is received at EL3, its handling
is delegated to plat_ea_handler() function. Platforms can provide their
own implementation of this function. This patch adds a weak definition
of the said function that prints out a message and just panics.
In order to support handling External Aborts at EL3, the build option
HANDLE_EA_EL3_FIRST must be set to 1.
Before this patch, HANDLE_EA_EL3_FIRST wasn't passed down to

Previously mem_protect used to be only supported from BL2. This is not
helpful in the case when ARM TF-A BL2 is not used. This patch demonstrates
mem_protect from el3_runtime firmware on ARM Platforms specifically
when RESET_TO_BL31 or RESET_TO_SP_MIN flag is set as BL2 may be absent
in these cases. The Non secure DRAM is dynamically mapped into EL3 mmap
tables temporarily and then the protected regions are then cleared. This
avoids the need to map the non secure DRAM permanently to BL31/sp_min.
The stack size is also increased, because DYNAMIC_XLAT_TABLES require

The patch adds the necessary changes to load HW_CONFIG in BL2 for
ARM Platforms :
1. The load address of HW_CONFIG is specified via the `hw_config_addr`
property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
property defines the maximum size to be expected for the HW_CONFIG.
The `arm_dyn_cfg_helpers.c` and corresponding header implements
utility functions to parse these DT properties defined.
The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
them to be invoked from ARM platform layer.
2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
the list of images to be loaded by BL2.
3. The `libfdt` sources are now included when BL2 is built
4. A new helper `populate_next_bl_params_config()` is introduced in
desc_image_load.c to populate the subsequent executable BL images
with the `hw_config` and the corresponding `fw_config` if available.
The `plat_get_next_bl_params()` API for ARM platforms is modified to
invoke this new helper.
5. The implementation of `bl2_early_platform_setup2()` is modified to
consider `arg0` as well in addition to `arg1` passed from BL1.
6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.

This patch add supports for the new API added for BL2 at EL3 for
FVP. We don't have a non-TF Boot ROM for FVP, but this option can be
tested setting specific parameters in the model.
The bl2 image is loaded directly in memory instead of being loaded
by a non-TF Boot ROM and the reset address is changed:
--data cluster0.cpu0=bl2.bin@0x4001000
-C cluster0.cpu0.RVBAR=0x4001000
These parameters mean that in the cold boot path the processor will
jump to BL2 again. For this reason, BL2 is loaded in dram in this
case, to avoid other images reclaiming BL2 memory.

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.

A Secure Partition is a software execution environment instantiated in
S-EL0 that can be used to implement simple management and security
services. Since S-EL0 is an unprivileged exception level, a Secure
Partition relies on privileged firmware e.g. ARM Trusted Firmware to be
granted access to system and processor resources. Essentially, it is a
software sandbox that runs under the control of privileged software in
the Secure World and accesses the following system resources:
- Memory and device regions in the system address map.
- PE system registers.
- A range of asynchronous exceptions e.g. interrupts.
- A range of synchronous exceptions e.g. SMC function identifiers.
A Secure Partition enables privileged firmware to implement only the
absolutely essential secure services in EL3 and instantiate the rest in
a partition. Since the partition executes in S-EL0, its implementation
cannot be overly complex.
The component in ARM Trusted Firmware responsible for managing a Secure
Partition is called the Secure Partition Manager (SPM). The SPM is
responsible for the following:
- Validating and allocating resources requested by a Secure Partition.
- Implementing a well defined interface that is used for initialising a
Secure Partition.
- Implementing a well defined interface that is used by the normal world
and other secure services for accessing the services exported by a
Secure Partition.
- Implementing a well defined interface that is used by a Secure
Partition to fulfil service requests.
- Instantiating the software execution environment required by a Secure
Partition to fulfil a service request.

An earlier patch added provision for the platform to provide secure
interrupt properties. ARM platforms already has a list of interrupts
that fall into different secure groups.
This patch defines macros that enumerate interrupt properties in the
same fashion, and points the driver driver data to a list of interrupt
properties rather than list of secure interrupts on ARM platforms. The
deprecated interrupt list definitions are however retained to support
legacy builds.
Configuration applied to individual interrupts remain unchanged, so no
runtime behaviour change expected.
NOTE: Platforms that use the arm/common function
plat_arm_gic_driver_init() must replace their PLAT_ARM_G1S_IRQS and
PLAT_ARM_G0_IRQS macro definitions with PLAT_ARM_G1S_IRQ_PROPS and
