Just a follow-up on the testing with TF-A and OP-TEE. Unfortunately, the patch series breaks the transfer list handoff to U-Boot completely and just end up with below error when U-Boot boots: ``` No valid device tree binary found at 0000000000000000 initcall failed at call 0000000060097bcc (err=-2) ### ERROR ### Please RESET the board ### ``` U-Boot test version: 'next' branch + this series + my patch [1] to point fdt_addr to gd->fdt_blob.
