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) ?
