└─>EFI handover protocol (DEPRECATED)
In linux kernel since version 6.2 (release Date: 2023-02-19)
Select this in order to include support for the deprecated EFI
handover protocol, which defines alternative entry points into the
EFI stub. This is a practice that has no basis in the UEFI
specification, and requires a priori knowledge on the part of the
bootloader about Linux/x86 specific ways of passing the command line
and initrd, and where in memory those assets may be loaded.
If in doubt, say Y. Even though the corresponding support is not
present in upstream GRUB or other bootloaders, most distros build
GRUB with numerous downstream patches applied, and may rely on the
handover protocol as as result.
