image: Add IH_OS_EFI for EFI chain-load boot
Add a new OS type to be used for chain-loading an EFI compatible
firmware or boot loader like GRUB2, possibly in a verified boot
scenario.
Bellow is sample ITS file that generates a FIT image supporting
secure boot. Please note the presence of 'os = "efi";' line, which
identifies the currently introduced OS type:
/ {
#address-cells = <1>;
images {
efi-grub {
description = "GRUB EFI";
data = /incbin/("bootarm.efi");
type = "kernel_noload";
arch = "arm";
os = "efi";
compression = "none";
load = <0x0>;
entry = <0x0>;
hash-1 {
algo = "sha256";
};
};
};
configurations {
default = "config-grub";
config-grub {
kernel = "efi-grub";
signature-1 {
algo = "sha256,rsa2048";
sign-images = "kernel";
};
};
};
};
