wdenk e2ffd59b4d * 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.
