I think your ROM code is what may need to change, not the entire MTD
subsystem.

Hello,
Meanwhile, to do this we use a small userspace program created by
Javier Martinez in order to flash the MLO in our OMAP3 boards. See
http://git.isee.biz/?p=pub/scm/writeloader.git;a=summary
I tried this with a 3.7 kernel and the following NAND; it does not work
for me

Hello,
on OMAP3, the NAND area holding MLO and u-boot need a different ECC scheme
(hw) than the rootfs (sw)
There is some discussion around this, please take a look at this thread,

AFAIK, there's no hardware limitation that would prevent us from setting
a per-partition ECC, keep in mind this effort is not reduced to make
devicetree accept ECC on the partitions.
