Hi Tony,
1. When building optee for K3, the generated optee output binary is under "/out/arm-plat-k3/core/tee-pager_v2.bin".
The binary "tee-pager_v2.bin" is re-named to "bl32.bin", and placed under "/board-support/prebuilt-images/bl32.bin".
The two files are the same.
2. Yes, you're right, this is a "typo". A72 => A53.
Best,
-Hong
