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 .
Best regards,
