      feat(hw_crc): add support for HW computed CRC · a1cedadf
      Manish V Badarkhe authored 
      

Added support for HW computed CRC using Arm ACLE intrinsics.
These are built-in intrinsics available for ARMv8.1-A, and
onwards.
These intrinsics are enabled via '-march=armv8-a+crc' compile
switch for ARMv8-A (supports CRC instructions optionally).

HW CRC support is enabled unconditionally in BL2 for all Arm
platforms.

HW CRC calculation is verified offline to ensure a similar
result as its respective ZLib utility function.

HW CRC calculation support will be used in the upcoming
firmware update patches.

      feat(plat/sgi): enable AMU for RD-V1-MC · e8b119e0
      Pranav Madhu authored 
      

AMU counters are used for monitoring the CPU performance. RD-V1-MC
platform has architected AMU available for each core. Enable the use of
AMU by non-secure OS for supporting the use of counters for processor
performance control (ACPI CPPC).

      refactor(plat/arm): store UUID as a string, rather than ints · 7d111d99
      David Horstmann authored 
      

NOTE: Breaking change to the way UUIDs are stored in the DT

Currently, UUIDs are stored in the device tree as
sequences of 4 integers. There is a mismatch in endianness
between the way UUIDs are represented in memory and the way
they are parsed from the device tree. As a result, we must either
store the UUIDs in little-endian format in the DT (which means
that they do not match up with their string representations)
or perform endianness conversion after parsing them.

Currently, TF-A chooses the second option, with unwieldy
endianness-conversion taking place after reading a UUID.

To fix this problem, and to make it convenient to copy and
paste UUIDs from other tools, change to store UUIDs in string
format, using a new wrapper function to parse them from the
device tree.

      refactor(plat/arm): replace FIP base and size macro with a generic name · 49e9ac28
      Manish V Badarkhe authored 
      

Replaced PLAT_ARM_FIP_BASE and PLAT_ARM_FIP_MAX_SIZE macro with a
generic name PLAT_ARM_FLASH_IMAGE_BASE and PLAT_ARM_FLASH_IMAGE_MAX_SIZE
so that these macros can be reused in the subsequent GPT based support
changes.

      plat: marvell: armada: a3k: Add new compile option A3720_DB_PM_WAKEUP_SRC · f2800a47
      Pali Rohár authored 
      

This new compile option is only for Armada 3720 Development Board. When
it is set to 1 then TF-A will setup PM wake up src configuration.

By default this new option is disabled as it is board specific and no
other A37xx board has PM wake up src configuration.

Currently neither upstream U-Boot nor upstream Linux kernel has wakeup
support for A37xx platforms, so having it disabled does not cause any
issue.

Prior this commit PM wake up src configuration specific for Armada 3720
Development Board was enabled for every A37xx board. After this change it
is enabled only when compiling with build flag A3720_DB_PM_WAKEUP_SRC=1

      feat(board/rdn2): add support for variant 1 of rd-n2 platform · fe5d5bbf
      Aditya Angadi authored 
      

Add board support for RD-N2 Cfg1 variant of RD-N2 platform. It is a
variant of RD-N2 platform with a reduced interconnect mesh size (3x3)
and core count (8-cores). Its platform variant id is 1.

      feat(plat/sgi): introduce platform variant build option · cfe1506e
      Aditya Angadi authored 
      

A Neoverse reference design platform can have two or more variants that
differ in core count, cluster count or other peripherals. To allow reuse
of platform code across all the variants of a platform, introduce build
option CSS_SGI_PLATFORM_VARIANT for Arm Neoverse reference design
platforms. The range of allowed values for the build option is platform
specific. The recommended range is an interval of non negative integers.

An example usage of the build option is
make PLAT=rdn2 CSS_SGI_PLATFORM_VARIANT=1
