I did come across a ramdom version of U-Boot which could load zImages,
but I don't have a pointer to that any more.
Also, does anyone know why U-Boot a

It's a valid point; also, the kernel changes ABI so frequen

Keeping a backup is a good idea, but installing it from your

Hey
There are a bunch of places where we generate uImages and which
duplicate information.
a kernel build most commonly outputs a zImage; this is then converted
to an uImage for u-boot consumption with some rune like:
mkimage -A arm -O linux -T kernel -C none \
-a 0x800080
