In arch/mips/lib/iomap.c there's this "#define PIO_MASK 0x0ffff"
which limits the ability to successfully call ioport_map() to the
first 64kB. This causes pata_pcmcia to error out on CF card
probe because devm_ioport_map() is called with the remapped
PCMCIA IO area, which is somewhere in MAP_BASE space.
I've temporarily removed the PIO_MASK check and pata_pcmcia
works as expected. Is there any way around this, other than
creating an Alchemy-specific ioport_map() function?
Thanks,
Manuel Lauss
