I'm looking for support for pxa310 MMC SDHC .
In the PXA310 SPEC:

     The MMC module is based on the standards outlined in the 
MultiMediaCard System
Specification Version 3.3.1. The SD module manages one SD or SDIO card 
based on the standards
outlined in the SD Memory Card Specification Version 1.10 and SDIO Card 
Specification Version
1.0

I'm doubting if the controller support SDHC (SD 2.0) ?
