[Thomas:
 - Add Config.in comment about Linux kernel dependency
 - Extend Config.in help text to indicate that a TI specific kernel is
   needed
 - Fetch using git:// since fetching from http://, since fetching over
   http:// doesn't work.]

+	  It builds the kernel module and the user space binaries.
+	  For older CPUs or kernels use the ti-gfx package.
