"Configuration" is just the kernel name on SD Card?  I get the point but
I don't think it's making much trouble.  GTA02 use of Qi is basically
elective but on GTA03 the packaging will already use the right name so
that's OK.  The worst that can happen is booting from NAND due to wrong
name in SD.

~ - It's not there already because you can't use FAT as a rootfs, and Qi
mounts the filesystem it got the kernel from as the rootfs.

~ - It's also less fragile from updating point of view to have the kernel
image live inside the actual rootfs.

~ - Kernel inside rootfs allows independent updating of multiple rootfs
on the same card as well, each with private kernel.

So I don't think it's good to support the split FAT / ext2 thing we
happen to be stuck with in NOR U-Boot (which we have only because ext2
parsing in U-Boot was broken at that time).
