Not easily.  We were hoping to be able to use the existing design and
just substitute a new chip, and give the manufacturer a different
firmware image.  But it's starting to look like that might be the best
long-term option.  Booting directly from NAND has been more trouble
than it's worth in general, so we were already leaning toward having
our next design boot from a small NOR or EEPROM instead.

I'll also have our hardware guy take another look for 4k parts that
don't require >1-bit ECC (and thanks for the link).

Thanks Scott
