      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

      Add SiP service to configure Arm Ethos-N NPU · 76a21174
      Mikael Olsson authored 
      

By default the Arm Ethos-N NPU will boot up in secure mode. In this mode
the non-secure world cannot access the registers needed to use the NPU.
To still allow the non-secure world to use the NPU, a SiP service has
been added that can delegate non-secure access to the registers needed
to use it.

Only the HW_CONFIG for the Arm Juno platform has been updated to include
the device tree for the NPU and the platform currently only loads the
HW_CONFIG in AArch64 builds.

      GICv3: GIC-600: Detect GIC-600 at runtime · b4ad365a
      Andre Przywara authored 
      

The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.

This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.

      plat/arm: Introduce TC0 platform · f5c58af6
      Usama Arif authored 
      

This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.

TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.

Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.

      FVP: Fix BL31 load address and image size for RESET_TO_BL31=1 · 6227cca9
      Alexei Fedorov authored 
      

When TF-A is built with RESET_TO_BL31=1 option, BL31 is the
first image to be run and should have all the memory allocated
to it except for the memory reserved for Shared RAM at the start
of Trusted SRAM.
This patch fixes FVP BL31 load address and its image size for
RESET_TO_BL31=1 option. BL31 startup address should be set to
0x400_1000 and its maximum image size to the size of Trusted SRAM
minus the first 4KB of shared memory.
Loading BL31 at 0x0402_0000 as it is currently stated in
'\docs\plat\arm\fvp\index.rst' causes EL3 exception when the
image size gets increased (i.e. building with LOG_LEVEL=50)
but doesn't exceed 0x3B000 not causing build error.

      plat/arm/sgi: introduce number of chips macro · 4d37aa76
      Vijayenthiran Subramaniam authored 
      

Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
multi-chip support to define number of chiplets on the platform. By
default, this flag is set to 1 and does not affect the existing single
chip platforms.

For multi-chip platforms, override the default value of
CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
platform. As an example, the command below sets the number of chiplets
to two on the RD-N1-Edge multi-chip platform:

export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

      Adds option to read ROTPK from registers for FVP · a6ffddec
      Max Shvetsov authored 
      

Enables usage of ARM_ROTPK_LOCATION=regs for FVP board.
Removes hard-coded developer keys. Instead, setting
ARM_ROTPK_LOCATION=devel_* takes keys from default directory.
In case of ROT_KEY specified - generates a new hash and replaces the
original.

Note: Juno board was tested by original feature author and was not tested
for this patch since we don't have access to the private key. Juno
implementation was moved to board-specific file without changing
functionality. It is not known whether byte-swapping is still needed
for this platform.

      doc: Split the User Guide into multiple files · 43f35ef5
      Paul Beesley authored 
      

The User Guide document has grown organically over time and
now covers a wide range of topics, making it difficult to
skim read and extract information from. Currently, it covers
these topics and maybe a couple more:

- Requirements (hardware, tools, libs)
- Checking out the repo
- Basic build instructions
- A comprehensive list of build flags
- FIP packaging
- Building specifically for Juno
- Firmware update images
- EL3 payloads
- Preloaded BL33 boot flow
- Running on FVPs
- Running on Juno

I have separated these out into a few groups that become new
documents. Broadly speaking, build instructions for the tools,
for TF-A generally, and for specific scenarios are separated.
Content relating to specific platforms (Juno and the FVPs are
Arm-specific platforms, essentially) has been moved into the
documentation that is specific to those platforms, under
docs/plat/arm.
