OK I'm seeing the following cache misaligned operation warning in my environment, did I miss something on my OPTEE build? => bootm 0x84000000 - 0x83000000 ## Booting kernel from Legacy Image at 84000000 ...

The alternative is to change the entry point address which requires an OPTEE change

This patch enables CONFIG_BOOTM_TEE. Once enabled its possible to chain-load Linux through OPTEE. Loading kernel to 0x80800000 => run loadimage Load FDT to 0x83000000 => run loadfdt Load OPTEE to 0x84000000 => fatload mmc 0:5 0x84000000 /lib/firmware/uTee.optee Then chain-load to the kernel via OPTEE => bootm 0x84000000 - 0x83000000 Image Name: Image Type: ARM Trusted Execution Environment Kernel Image (uncompressed) Data Size: 249844 Bytes = 244 KiB Load Address: 9dffffe4 Entry Point: 9e000000 Verifying Checksum ...
