fatload command can be used to load the EFI payload since EFI system
partition is always a FAT partition. Call into EFI code from
do_fat_fsload() to set the device path from which the last binary was
loaded. An EFI application like grub2 can’t find its configuration
file without the device path set.
load command (do_load_wrapper()) already calls efi_set_bootdev().
There is no need to move the call to do_load() as EFI system partition
is always a FAT partition.
Thanks for reporting the issue.
U-Boot has no restriction to EFI/FAT partitions when starting EFI
applications though of cause EFI/FAT is the normal way to do it.

We have the same already in cmd/fs.c for the 'load' command. I think we
should move it from cmd/fs.c to do_load(). Then we cover all file systems.
Could you, please, update the patch accordingly and resend it to me.
Best regards
