This toolchain provides multiple cross compilers and are publicly available on www.developer.arm.com We thoroughly test TF-A in CI using: AArch32 bare-metal target (arm-none-eabi) AArch64 ELF bare-metal target (aarch64-none-elf) Change-Id: I2360a3ac6705c68dca781b85e9894867df255b3e Signed-off-by: Madhukar Pappireddy <madhukar.pappireddy@arm.com>

Texas Instruments K3
|
|
====================
|
|
|
|
Trusted Firmware-A (TF-A) implements the EL3 firmware layer for Texas Instruments K3 SoCs.
|
|
|
|
Boot Flow
|
|
---------
|
|
|
|
::
|
|
|
|
R5(U-Boot) --> TF-A BL31 --> BL32(OP-TEE) --> TF-A BL31 --> BL33(U-Boot) --> Linux
|
|
\
|
|
Optional direct to Linux boot
|
|
\
|
|
--> BL33(Linux)
|
|
|
|
Texas Instruments K3 SoCs contain an R5 processor used as the boot master, it
|
|
loads the needed images for A53 startup, because of this we do not need BL1 or
|
|
BL2 TF-A stages.
