FWIW, I had the exact same issues with my Mistral AM37x EVM board. I not
only had to remove/deassert CONFIG_MTD_NAND_OMAP_HWECC, but also had to roll
back nand_base.c and nand_bbt.c back to their 2.6.32 versions (later ones
between .32 and .35 might have worked but I didn't bother trying) to be able
to read, error-free and correctly, NAND that was erased and written with a
.32-era kernel.
Best,
Grant Erickson
