Thanks. I checked out the 2.4 sdcard.c and compared it with the 2.6
tssdcard.c. What bugs me is that DMA transfer source SAR_BASE0 address
and destination DAR_BASE0 are always the same and driver does not make
any effort to check sd_state to see whether this is a read or write
operation. It is as if the DMA was never meant to be used for write
operations.
