Subject: libata-sff: Allow for wacky systems
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
There are some Linux supported platforms that simply cannot hit the low I/O
addresses used by ATA legacy mode PCI mappings. These platforms have a window
for PCI space that is fixed by the board logic and doesn't include the
neccessary locations.
Provide a config option so that such platforms faced with a controller that
they cannot support simply error it and punt
