LoongArch: Add EFI binary support for kexec_file
This patch creates kexec_efi_ops to load EFI binary file for
kexec_file_load() syscall.
The efi_kexec_load() as two parts:
- the first part loads the kernel image (vmlinuz.efi or vmlinux.efi)
- the second part loads other segments (e.g: initrd, cmdline, etc)
Currently, pez (vmlinuz.efi) and pei (vmlinux.efi) format images are
supported.
The basic usage (vmlinuz.efi or vmlinux.efi):
1) Load second kernel image:
# kexec -s -l vmlinuz.efi --initrd=initrd.img --reuse-cmdline
2) Startup second kernel:
# kexec -e
