* Patch by Lutz Dennig, 10 Apr 2003:LABEL_2003_04_15_1900

  Update for R360MPI board

* Add new meaning to "autostart" environment variable:
  If set to "no", a standalone image passed to the
  "bootm" command will be copied to the load address
  (and eventually uncompressed), but NOT be started.
  This can be used to load and uncompress arbitrary
  data.

* Set max brightness for MN11236 displays on TRAB board
