imx-atf boot flow

segfault

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.
