Subject: * The PS/2 mux on the BMS2003 board needs 450 ms after power on  
 before we can access it; add delay in case we are faster (with no   CF card
 inserted)

* Cleanup of some init functions

* Make sure SCC Ethernet is always stopped by the time we boot Linux
  to avoid Linux crashes by early packets coming in.

* Accelerate flash accesses on LWMON board by using buffered writes
