Hello, U-Boot is not able too boot on imx8mm and imx8mp and gives out of memory errors:

Reverting it, allows U-Boot to boot again. The issue seems to occur on modules with >=4Gb of RAM. Do you have any idea what might be causing the issue? On our boards, the first error occurs in efi_init_early() and then in initr_mmc(), and it happens during memory allocation using lmb. Best Regards, João Paulo Gonçalves
