[PATCH v5] mtd: support BB SRAM on ICP DAS LP-8x4x

2015-12-15 Thread Sergei Ianovich
This provides an MTD device driver for 512kB of battery backed up SRAM on ICPDAS LP-8X4X programmable automation controllers. SRAM chip is connected via FPGA and is not accessible without a driver, unlike flash memory which is wired to CPU MMU. This SRAM becomes an excellent persisent storage of
