| 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. |
