Sorry, I wasn't aware of your work in this area when I wrote sc520cdp.c and
decided to contribute it. My main goal was to use the flash for a JFFS
filesystem, so this strange mapping used by the BIOS wasn't a problem for me.

I tend to agree, though the fact that we are deviating from the BIOS's
configuration this way makes me wonder if there should be a config option
for it. OTOH, MTD already has more than enough config options already
and I'm hesitant to add another one. (Just try to imagine how to write a
one-paragraph entry for Configure.help to explain to people what this option
does without scaring them away).
