Oops, I expected CF/pcmcia to be directly hooked up to the pxa interface...
Does this mean that we will have to work on the Asic3 driver to get
pcmcia working?

If this is true, this may make sense to implement SD support first to
get familiar with the existing Asic3 driver first.

    Thanks for everything!
