ata: Report 16/32bit PIO as best we can
The legacy old IDE ioctl API for this is a bit primitive so we try and map stuff sensibly onto it. - Set PIO over DMA devices to report 32bit - Add ability to change the PIO32 settings if the controller permits it - Add that functionality into the sff drivers - Add that functionality into the VLB legacy driver - Turn on the 32bit PIO on the ninja32 and add support there Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
