    pxa2xx PCMCIA timing issue on iPAQ H5550
    
    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.
