I would prefer more testing over user/developer compability.

But if you resize the partition for u-boot be sure to resize to 256k and
not 192k, since this would cause a lot more problems than needed for us
using flash chips with 128k block size. Not a big problem but an issue.

I would love to see USB support implemented.
