Hey all,


I am looking for a way to use the 128 KB on-chip SRAM from our Linux platform (mainline 3.10.x). In the reference manual, I see that the SRAM is part of the DIGCTL block and in the DeviceTree I see a digctl@8001c000 part. But I have no idea how to enable this and how I would be able to use this part of memory, preferably from user-space. Can anyone help me in the right direction?
