* 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.
