[PATCH] parport: add parallel port support for SGI O2
Add support for the built-in parallel port on SGI O2 (a.k.a. IP32).
Define a new configuration option: PARPORT_IP32. The module is named
parport_ip32.
Hardware support for SPP, EPP and ECP modes along with DMA support when
available are currently implemented.
