Hi,
imx-atf allows alternative boot flow by preloading a BL33 (custom) image into memory.
Are there any instructions on how to use BL2 to boot an EL3 payload for pre-production test work ? How to use EL3_PAYLOAD_BASE common build parameter ?
Also, there is the FIP build command "make PRELOADED_BL33_BASE=0x80000000 PLAT=imx8qm all fip". Does i.MX8QM plaform support this? Can it be used to allow booting a custom image (like Linux kernel or some app) from TF-A ?
Thanks for any suggestions.

BL2_AT_EL3: This is an optional build option that enables the use of BL2 at EL3 execution level.
