The problem with using the two flash planes is that it
is not a very orthogonal solution.
I've got my flash split into three: bootloader, application
and JFFS2. The JFFS2 area is large enough that it derails this
It would be nice if a scheme to deal with this issue was a bit more
broadly applicable than just the at49xxxx.
