+  This driver provides a method to access memory not used by the kernel
+  itself (i.e. if the kernel commandline mem=xxx is used). To actually
+  use slram at least mtdblock or mtdchar is required (for block or
+  character device access).
+
+  Usage:
+
+  if compiled as loadable module:
+    modprobe slram map=<name>,<start>,<end/offset>
+  if statically linked into the kernel use the following kernel cmd.line
+    slram=<name>,<start>,<end/offset>
+
+  <name>: name of the device that will be listed in /proc/mtd
+  <start>: start of the memory region, decimal or hex (0xabcdef)
+  <end/offset>: end of the memory region. It's possible to use +0x1234
+                to specify the offset instead of the absolute address
+    
+  NOTE:
+  With slram it's only possible to map a contigous memory region. Therfore
+  if there's a device mapped somewhere in the region specified slram will
+  fail to load (see kernel log if modprobe fails).
