RE: [microblaze-uclinux] Adding parameters from the EDK project

Rick,

Hardware configuration values like the parameters actually go in the
.mhs file, not the .mss.  EDK generates xparameters.h including these
hardware values.  Configuration of the drivers is much less common, or
useful.  Note that values tend not to appear in the .mhs file unless
they differ from the default specified in the .mpd file for the core.
