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";
         };
     };
 };

};
