is the ucFS able to support the eMMC card on RSI  ?

Hello all:

    the bf607 processor's RSI interface can support the eMMC card. the description in datasheet of BF607 is "Support for eMMC 4.3 embedded NAND flash devices", and the customer wants to use the ucFileSystem, we find the below in the release note of ucFS:  

   ADSP-BF606, ADSP-BF607, ADSP-BF608, ADSP-BF609
               o Devices supported: RAM Disk, SD Card, USB Mass Storage

so is the ucFS able to support the eMMC card on RSI  ?  or it must be a SD Card if using this filesystem.
