When the source code says 'SMCC' it is talking about the SMC Calling
Convention. The correct acronym is SMCCC. This affects a few definitions
and file names.
Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

The CI has been updated to run tests against the AEMv8-A RevC
model, FVP_Base_RevC-2xAEMv8A, which is available from the Fast
Model releases on Connected Community [1].
Additionally, the CI now also includes the Cortex-A55x4, Cortex-A75x4
and Cortex-A55x4-A75x4 Base models.

Update Arm Trusted Firmware references in the upstream documents to
Trusted Firmware-A (TF-A). This is for consistency with and
disambiguation from Trusted Firmware-M (TF-M).
Also update other Arm trademarks, e.g. ARM->Arm, ARMv8->Armv8-A.

The FVP platform port for SP_MIN (BL32) didn't map the flash memory
in BL32 for stroring the mem_protect enable state information leading
to synchronous exception. The patch fixes it by adding the region to
the BL32 mmap tables.

When querying `SMCCC_ARCH_WORKAROUND_1` through `SMCCC_ARCH_FEATURES`,
return either:
* -1 to indicate the PE on which `SMCCC_ARCH_FEATURES` is called
requires firmware mitigation for CVE-2017-5715 but the mitigation
is not compiled in.
* 0 to indicate that firmware mitigation is required, or
* 1 to indicate that no firmware mitigation is required.
This patch complies with v1.2 of the firmware interfaces
specification (ARM DEN 0070A).

This patch updates the `firmware-design.rst` document for
changes in ARM-TF for supporting dynamic configuration features
as presented in `Secure Firmware BoF SFO'17`[1].
The patch also updates the user-guide for 2 build options for FVP
pertaining to dynamic config.

Previously, Juno used to depend on the SSC_GPRETN register to inform
about the reset syndrome. This method was removed when SCP migrated
to the SDS framework. But even the SDS framework doesn't report the
reset syndrome correctly and hence Juno failed to enter Firmware
update mode if BL2 authentication failed.
In addition to that, the error code populated in V2M_SYS_NVFLAGS register
does not seem to be retained any more on Juno across resets. This could
be down to the motherboard firmware not doing the necessary to preserve
the value.
Hence this patch modifies the Juno platform to use the same mechanism to
trigger firmware update as FVP which is to corrupt the FIP TOC on
authentication failure. The implementation in `fvp_err.c` is made common
for ARM platforms and is moved to the new `arm_err.c` file in
plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
are modified to allow write to the Flash memory address.

This issue was detected when testing FWU on Juno. The Timer
`timer_ops` was not being initialized before being used by
the SDS driver on Juno. This patch adds the call to
`generic_delay_timer_init()` during bl2u_early_platform_setup().
This is done generically for all ARM platforms because the
cost involved is minimal.

This patch modifies the common utility function
`populate_next_bl_params_config()` to only modify the entrypoint arguments
to an executable image only if they are not initialized earlier.
This issue was detected while testing Optee on ARM platforms which needed
the current arguments to be preserved in the absence of corresponding
config files.

MAP_TSP_MEM could be either in SRAM or DRAM. When MAP_TSP_MEM is in
DRAM, it's overlapped with MAP_DDR.
Since TSP_MEM is always configured in DRAM case, it means

Although SRAM is initialized, DCACHE should be cleaned too.
Because MCU is a parrallel core to access SRAM. We need to make
