Hi Bruce,
Sorry for the dumb question, I just can figure out the right google search to find what I'm trying to do. I'm running 2.6.27-rc4 on an mpc8347 with a 32KiB nvSRAM (Cypress CY14B256L) on the local bus. We just want to be able to access this memory from user space seperately from "main" memory. We've got a process that needs to be able to remember info through power cycles. Can anyone point me to an article or some code snippet that does something like this so I can sink my teeth into it?
Assuming your bootloader sets up the local bus access windows (physical address of the SRAM) and timing so that you can read/write to the SRAM, then once Linux boots, you should be able to just use /dev/mem as you would to access any other device registers at a specific address.
