-	  The Advanced XIP File System is a Linux kernel filesystem
-	  driver that enables files to be executed directly from flash
-	  or ROM memory rather than being copied into RAM. It has the
-	  ability to store individual *pages* in a file
-	  uncompressed/XIP or compressed/Demand Paged.
-
-	  So far, the only supported mode is 'XIP all', so all the
-	  files that have the execute attribute set will be XIP'ed.
-
-	  At the moment, the FS is not supported in Linux mainline
-	  (v4.3-rc5), so the kernel has to be built with the axfs
-	  patches to be able to read it. Patches can be found at:
