[Strange. I _did_ check these in before. Seems SF restored an old

version of the repository???]

* Patch by Reinhard Meyer, 09 Jan 2004:
  - add RTC support for MPC5200 based boards (requires RTC_XTAL)

* Add support for IDE LED on BMS2003 board
  (exclusive with status LED!)

* Add support for PS/2 keyboard (used with PS/2 multiplexor on
  BMS2003 board)

* Patches by Reinhard Meyer, 4 Jan 2004 + 7 Jan 2004:
  Add common files for "emk" boards
