MMIO doesn't work at all?
I'm a bit reluctant to push this into mainline, particularly when I feel
that the sata_sil driver could still be updated to use only 32-bit MMIO
transactions without much problem.
Hello, Kevin, Jeff.
IIRC, Kevin's platform can't do any MMIO. Also, although sata_sil can
be made to use 32-bit address space exclusively, I think having PIO
access in the meantime can be helpful to many newer ATI mips platforms
out there. Please note that w/ ioread/write change, the modified code
is isolated into init_one(), so the added complexity is small.
Thanks.
