Why do we pass memory map both in e820 and efi_info

Hi Dave/Chao,

I am going through kexec-tools code and it looks like that for EFI
systems, we pass memory map entries both in bootparams e820 memory map
as well as efi_info. I am wondering why that's the case?

IOW, I am also trying to figure out as a bootloader, when should we
pass memmap in e820 and when should it be passed in efi_info.
