* 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
