They are device identifiers in EFI format. E.g. This
static grub_uint8_t devpath_5[] = {
    0x01, 0x03, 0x18, 0x00, 0x0B, 0x00, 0x00, 0x00,
    0x00, 0x40, 0xCB, 0xFF, 0x00, 0x00, 0x00, 0x00,
    0xFF, 0xBF, 0xFF, 0xFF, 0x00, 0x00, 0x00, 0x00,
    0x04, 0x06, 0x14, 0x00, 0xEB, 0x85, 0x05, 0x2B,
    0xB8, 0xD8, 0xA9, 0x49, 0x8B, 0x8C, 0xE2, 0x1B,
    0x01, 0xAE, 0xF2, 0xB7, 0x7F, 0xFF, 0x04, 0x00,

Means MMIO(EfiMemoryMappedIO,
I can add necessary prototypes and structures
