OMAP3 SDXC support

Hi,

As for now I'm running multiple system with SDXC I(UHS-I) 64GB with OMAP3. I want to know if there is any risk related to do this since:

As describe in the OMAP35x Technical Reference Manual (Re. X) (spruf98x.pdf) in section:

22.1.1 MMC/SD/SDIO Features

• Full compliance with MMC command/response sets as defined in the Multimedia Card System
Specification, v4.2 including high-capacity (size > 2GB) cards HC MMC.

• Full compliance with SD command/response sets as defined in the SD Memory Card Specifications,
v2.0 including high-capacity SDHC cards up to 32GB.

Also, the sdcard.org says that it's ok to use SDXC with spec 2.0:

more precisely:

and

1- So does the OMAP3 host controller for MMC have a limitation supporting the UHS-I SDXC card?

2- Will you recommend only SDXC 64GB class 10 (spec version 2.0) and not SDXC UHS-1 (spec version 3.0)? Is there a limit?

thanks,
