Interfacing a BF52X to a NXP SDIO101 device

We desperately need a faster/more reliable SD card interface to our BF52X design. This device looks like it might be a good match. Some level translation looks necessary to interface the control/data bus which can be managed.


The usual questions follow:


1. Has anyone else used this part with a Blackfin?

2. Are there any other similar devices  that have been successfully deployed?

3. (For extra credit) Does anyone have a view on the level of similarity between the BF54X internal SDH controller and the NXP device? I am hoping the SDH device driver framework can be reused to a greater degree.
