[Resend...forgot to send to lkml]
We are currently reserving one byte more than actually needed
by the flash device and overlapping into the next I/O expansion
bus window. This a) causes us to allocate an extra page of VM due
to ARM ioremap() alignment code and b) could cause problems
if another driver tries to request the next expansion bus window.
