* Code cleanup, mostly for GCC-3.3.x
* Cleanup confusing use of CONFIG_ETH*ADDR - ust his only to
pre-define a MAC address; use CONFIG_HAS_ETH* to enable support for
additional ethernet addresses.
* Cleanup drivers/i82365.c - avoid duplication of code
* Fix bogus "cannot span across banks" flash error message
* Add support for CompactFlash for the CPC45 Board.
