The image includes OOB data, because the rom-mandated map is different
from normal standards. If OOB is zeroed, blocks appear as bad (correctly!).
By memsetting to 0xff, before filling

I didn't know. I used what u-boot offers, which works for me without

The tool works for me, with imx28 and NAND memory, but the resulting
blocks are reported as bad, both by u-boot and the kernel.
This makes it impossible to erase from Linux (for an upgrade without
console access, for example -- u-boot can "nand scrub" but linux can't).
pre-filling with 0xff
