By reading reference manual I understand that I can use SDMA for eCSPI communication with one of the SPI devices, which further suggests that "mcu_2_shp" and "shp_2_mcu" are the generic scripts to do transfers. I am using Linux kernel 3.14, Please provide guidance to how to configure these scripts (i.e. providing source/destination addresses and other required things)?
Also, I am inclined to write a loadable module for this configuration. Please suggest if any further way around is there.
