[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
