The PXA27x controller works even with SDXC , that is tested. I suspect there might be some change in the PXA3xx controller, but I don't really know for sure. You'd have to check. Also, you didn't really answer my question with regards to porting U-Boot above. If you do that, use latest mainline, not 2014.01 .
