From: Milan Plzik Recently I've been trying to get working PCMCIA interface on H5000 ipaq series, using dual PCMCIA sleeve. So far things work correctly, but I had to do one modification to drivers/pcmcia/pxa2xx_base.c to get the interface working with orinoco gold PCMCIA card (wired pcnet_cs ethernet card worked even without this modification). The issue has something to do with assert time on PCMCIA bus, but I'm not really sure what -- I found the working value just by trial&error approach. I'm not sure how is the assert value in pxa2xx_mcxx_asst calculated (I know, simple formula, but the reason why is it calculated that way is not obvious for me), neither that my modification is correct. It just works with iPAQ.
