yes, we have. But we only have one gpmi.

I ever tried to use different dma channels for different chip selects.
But after discussed with our IC guy, it is proved to be meaningless.
We only have one gpmi, and so we only have one data bus. Even we have 4 
dma channels
, we have to do the DMA operations one by one.
