Merge patch series "Allow falcon boot from A-core SPL on K3 devices"
Anshul Dalal <[email protected]> says:
With the addition of secure falcon mode since commit 7674ac9c820f ("Merge patch
series "Add support for secure falcon mode: disable args file""), this series now
adds support for the same to TI's K3 devices and documents the feature taking
AM62x EVM as an example.
With secure falcon mode from A-Core SPL, the boot flow changes as follows:
Existing:
R5 SPL -> TFA -> OP-TEE -> A-Core SPL -> *U-Boot* -> Linux Kernel
Modified:
R5 SPL -> TFA -> OP-TEE -> A-Core SPL -> Linux Kernel
