Trusted Firmware-A for Texas Instruments K3 SoCs ================================================ 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.
