[Tejas]: I've provided two logs: one obtained from the latest u-boot origin/master, resulting in the "ERROR: reserving fdt memory region failed" error, and the other from reverting commit 06d514d77c37 ("lmb: consider EFI memory map"), which leads to the "efi_free_pool: illegal free" error.
Thank You,
Tejas.
