If we want to actually go there, I think the best option for PCMCIA
support is likely to replace the entire "soc_common" pcmcia driver
with a simple drivers/pata/ storage driver and no support for
other cards. There was a driver until commit 38943cbd25a2
("ata: remove palmld pata driver") that could serve as an
template.
