acrn-hypervisor/misc/efi-stub/multiboot.h
Toshiki Nishioka a9cc4b7629 efi-stub: add acrn efi application as an alternative bootloader for secure boot 
ACRN EFI application based on the legacy efi-stub code provides booting method
of HV on UEFI-BIOS without using the GRUB Bootloader. It is supposed to be used
for secure booting on certain platform. By means of that users can boot HV,
Service VM kernel, pre-launched VM kernel and its ACPI table binary packed in
the Slim Bootloader container boot image file format. ACRN EFI application has
additional dependencies to compile which are not listed in the existing ACRN GSG
doc. Since this is an optional feature but not all users need, it does not get
compiled by default to avoid causing any confusion for existing users. README
for how to use the feature will come later in a separated commit.
