This looks good to me, assuming that the higher levels support 8-bit busses, switching to them, etc.

This revision is now accepted and ready to land.Feb 21 2015, 2:18 PM

This looks good to me. The upper layers were already handling 8-bit for the one 8-bit controller we had (beaglebone). Now we're positioned to handle it for all sdhci controllers that can do 8 bit.
