Accessing SRAM from Linux on T-Series Processors

We are going to attach an SRAM on the IFC interface of T1042 processor. I want to know how can we configure IFC in u-boot to support SRAM in addition to other NOR flashes already present on difference chip selects of IFC controller.

 

In addition to that, how can I access the SRAM afterwards in Linux? Is there any existing generic driver for SRAMs, do I need to write my own driver or can I access the memory mapped SRAM from /dev/mem in userspace? Which one of the mentioned three options is feasible?
