+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.
