I have a a custom iMX6q board, It has is uboot and kernel in Weim NOR and rootfs in eMMC, it is booting just fine, however,  i have an FPGA connected on the EIM bus.

 

Following are the connection,

 

CS1

26 bit address lines

lower order data bus

 

Now i want to access the FPGA as an SRAM. I have the resources to write a block ram into the FPGA.

But i am new to writing drivers in Linux.

 

I am trying to find out an existing RAM driver in the BSP.

 

During m search i came across MTD_RAM and MTD_PLATRAM

 

Can anyone tell me what they do and can they help me in accessing the SRAM i write in the FPGA.

 

 

help would be appreciated,

nishad
