MIPS ioport_map and Au1xxx PCMCIA

[Manuel Lauss <mano@roarinelk.homelinux.net>]

Hello,

the file arch/mips/lib/iomap.c contains this define
#define PIO_MASK 0x0ffffUL

which prevents pata_pcmcia with the new devres stuff
from attaching to a CF card. (on my Au1200).
The ports-to-be-iomap()'ed are in the 0xc0000000 range
and the ioport_map() function rejects all attempts
of pata_pcmcia to devm_ioport_map() them.

What is this mask used for and can it be removed?

Thanks,
