Great! Thanks for giving NAND a chance :-)

Could you try using the devicetree snippet below?

nand@d0000 {
	/* HACK: Use legacy compatible to handle smaller pages */
	compatible = "marvell,pxa3xx-nand";
	status = "okay";
	num-cs = <1>;
	marvell,nand-keep-config;
	marvell,nand-enable-arbiter;
	nand-on-flash-bbt;

	/* partitions */
};

Please check if your device is detected and try to do some reading
first. If that works, you can try to mount the filesystem, or write
a new kernel.

If the above works, I'll prepare a proper patch.

Thanks!
