default redboot is using the wrong machine id (iirc iq31244 machine id)
so you have to use things like devio to modify r1 register before
booting the kernel. I use a script doing roughly that :
(
devio 'wl 0xe3a01c04,4' 'wl 0xe38110bc,4'
cat arch/arm/boot/zImage
) > arch/arm/boot/zImage.ss4000e
And then, use the zImage.ss4000e.
