libata/drivers: Add driver for Apple "MacIO" IDE controller (88358ab0) · Commits · 戴 / test

This is a libata driver for the "macio" IDE controller used on most Apple PowerMac and PowerBooks. It's a libata equivalent of drivers/ide/ppc/pmac.c It supports all the features of its predecessor, including mediabay hotplug and suspend/resume. It should also support module load/unload. The timing calculations have been simplified to use pre-calculated tables compared to drivers/ide/pmac.c and it uses the new mediabay interface provided by a previous patch. Signed-off-by:

		Most IDE capable PowerMacs have IDE busses driven by a variant
		of this controller which is part of the Apple chipset used on
		most PowerMac models. Some models have multiple busses using
		different chipsets, though generally, MacIO is one of them.
