+	 This provides an MTD device driver for 512kiB 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.
+
+	 Say N, unless you plan to run this kernel on LP-8X4X.
+
+	 If you say M, the module will be called sram_lp8x4x.
