I am using SPI2, it seems the EDMA priority is not enough to transfer data quickly. How to change the EDMA priority?

Please refer Master Priorities Register 0/1 in the ARM Subsystem User Guide, page 145.

Hi Marcus,

What file do i need to edit to set this Master Priorities register 0/1.

Is it in the linux kernel davinci driver code or is it in uboot that i can access these registers

thanks in advance
