[U-Boot] [PATCH 0/2] efi_loader: print information about loaded UEFI images

If an exception occurs in a UEFI loaded image we need the start address of
the image to determine the relocation offset.

This patch series adds the necessary lines after the registers in the crash
dump. A possible output would be:

UEFI image
start 0x7fdb4000, size 0xa7b60
pc offset 0x72ca
/\snp.efi

With the offset 0x72ca we can now find the relevant instruction in the
disassembled 'snp.efi' binary.
