I'm trying to connect a NAND flash to the BF606.
Does the RSI on BF60x supports the MMC 4.41 version ?
The BF60x actually supports MMC 4.3, but many features of 4.41 can be supported in software (as indicated in the thread that Suraj directed you to above). What extensions beyond 4.3 are of interest to you?
The RSI on BF60x supports MMC 4.1, there is a similar discussion on the below link that may help you.
