Thanks :) Read performance drops noticeably if we don't have hardware
ECC. With it, I get about 6.7 MB/s, without it 5.2 MB/s. (nanddump
from a "raw" MTD partition.)

I think it was even much worse in the GTA01, with its slow processor.
(For reference, that one does about 4 MB/s, with hardware ECC.)
