Build as an EFI application

Type: bool

Help

Build as an EFI application.

This works by creating a "zephyr.efi" EFI binary containing a zephyr
image extracted from a built zephyr.elf file.  EFI applications are
relocatable, and cannot be placed at specific locations in memory.
Instead, the stub code will copy the embedded zephyr sections to the
appropriate locations at startup, clear any zero-filled (BSS, etc...)
areas, then jump into the 64 bit entry point.
