void MI_Card_NDmaCopy( u32 ndmaNo,

               const void* src,

               void *dest,

               u32 size);

Uses the new DMA to copy using a card interrupt. DMA will run when a card interrupt occurs.

It uses the new DMA to perform copies in word (4-byte) units. Both the transfer source address (src) and the transfer destination address (dest) must be 4-byte aligned. The transfer size (size) needs to be a multiple of 4.
