Actually, it's almost supported by the base PASemi code anyway, there is a
PCMCIA driver in setup.c, but our hardware has been changed enough to make it
hang the system when used. I should probably take another look and see If I
can fix that. The other option would be to move the above patch to where we
add our rtc platform device. One thing that does confuse me is the interrupt,
it's attached to GPIO 0, so should be on the mpic int 0 (or maybe 16?)but I
could never get it to work.
