BF707 EZ-KIT SPI Flash read/write in DMA mode

Hi,

Is it possible to do the Flash read/write in BF707 EZ-KIT using SPI DMA mode?

I had tried combining the SPI Flash readback code and SPI DMA mode sample code available in CCES. But couldn't access the Flash. 

Also the SPI DMA sample code seems to be incomplete. It would be really helpful if you could share a sample code for the flash read/write or for the proper configuration of DMA.
