Subject: Reason for PIO_MASK?
Date: Sat, 3 Oct 2009 16:48:12 +0200	[thread overview]
Message-ID: <f861ec6f0910030748l396b45bck858f15460354e58e@mail.gmail.com> (raw)

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
