The Cortex-X3 cpu port was developed before its public release when it was known as Makalu ELP. Now that it's released we can use the official product name. Signed-off-by: Boyan Karatotev <boyan.karatotev@arm.com> Change-Id: Iebb90cf2f77330ed848a3d61c5f6928942189c5a

TC Total Compute Platform
|
|
==========================
|
|
|
|
Some of the features of TC platform referenced in TF-A include:
|
|
|
|
- A `System Control Processor <https://github.com/ARM-software/SCP-firmware>`_
|
|
to abstract power and system management tasks away from application
|
|
processors. The RAM firmware for SCP is included in the TF-A FIP and is
|
|
loaded by AP BL2 from FIP in flash to SRAM for copying by SCP (SCP has access
|
|
to AP SRAM).
|
|
- GICv4
|
|
- Trusted Board Boot
|
|
- SCMI
|
|
- MHUv2
|
|
|
|
Currently, the main difference between TC0 (TARGET_PLATFORM=0), TC1
|
|
(TARGET_PLATFORM=1), TC2 (TARGET_PLATFORM=2) platforms w.r.t to TF-A
|
|
is the CPUs supported as below:
|
|
|
|
- TC0 has support for Cortex A510, Cortex A710 and Cortex X2.
|
|
- TC1 has support for Cortex A510, Cortex Makalu and Cortex X3.
|
|
- TC2 has support for Hayes and Hunter Arm CPUs.
|
|
|
|
|
|
Boot Sequence
|
|
-------------
|
|
|
|
The execution begins from SCP_BL1. SCP_BL1 powers up the AP which starts
|
|
executing AP_BL1 and then executes AP_BL2 which loads the SCP_BL2 from
|
|
FIP to SRAM. The SCP has access to AP SRAM. The address and size of SCP_BL2
|
|
is communicated to SCP using SDS. SCP copies SCP_BL2 from SRAM to its own
|
|
RAM and starts executing it. The AP then continues executing the rest of TF-A
|
|
stages including BL31 runtime stage and hands off executing to
|
|
Non-secure world (u-boot).

Build Procedure (TF-A only)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- Obtain `Arm toolchain`_ and set the CROSS_COMPILE environment variable to
|
|
point to the toolchain folder.
|
|
|
|
- Build TF-A:
|
|
|
|
.. code:: shell
|
|
|
|
make PLAT=tc BL33=<path_to_uboot.bin> \
|
|
SCP_BL2=<path_to_scp_ramfw.bin> TARGET_PLATFORM={0,1,2} all fip
|
|
|
|
Enable TBBR by adding the following options to the make command:
|
|
|
|
.. code:: shell
|
|
|
|
MBEDTLS_DIR=<path_to_mbedtls_directory> \
|
|
TRUSTED_BOARD_BOOT=1 \
|
|
GENERATE_COT=1 \
|
|
ARM_ROTPK_LOCATION=devel_rsa \
|
|
ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem
