I admit I gave up too easily yesterday, built a Robert Nelson 3.12.13
and got my F20 image going with that. After I got running, I did update
the Fedora kernel to current 3.13.6 and tried to boot that. Same
problem, mmc driver not loading. I'll try to get to the bottom of this
afternoon. I'll diff the fedora/RN kernel config and see if anything
jumps out. If not, I'll start looking at am3* dts/dtsi files....
Robert, if you're reading this, don't suppose you can point me in the
direction of where to start looking? ;)
v3.13.x pretty much works out of the box, so no dts/dtsi changes are necessary..
I'd first start looking at make sure the mmc driver is setup:
CONFIG_TI_EDMA=y
CONFIG_DMA_ENGINE=y
