Hi Heinrich,

In case there is no EFI stub LoongArch would use elf format vmlinux, there
is no real "raw" image for us.

bootelf can't be used at the moment as it doesn't setup FDT and other environments
properly.

I'm planning to implement a bootlinuxelf command for this case, as MIPS, LoongArch,
xtensa are all using ELF as default kernel image format.
