Packing barebox within an uimage gives us integrity checking.
Generate the image with:
./scripts/mkimage -A arm -O barebox -T firmware -C none -d barebox.bin -a 0xffffffff barebox.uimage

You are right, it does. But then, I am asking myself, why is there a OS
definition for 'barebox', when we aren't using it in the first place?

Christian

It's derived from U-Boot where it initially was:
#define IH_OS_U_BOOT 17 /* Firmware */
When renaming U-Boot to barebox this was one of the occurences of
'U_BOOT' that shouldn't have been renamed.
