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"; }; }; }; }; Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@gmail.com> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
