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.
