This change is in preparation for condtitionial compile support in the

patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

Fix USB support issue for MPC8641HPCN board.
The configuration file has already enabled USB, but it
missed definition of CFG_OHCI_SWAP_REG_ACCESS, the USB

register endian.
usb_cpu_init() configures GPS USB pins, clocks, etc. and

changes for IDS8247 board support

- FCC2 is deactivated
- FCC1 is activated
- I2C is activated
- CFI driver is activated
- Adapted for use with LIBFDT
Wolfgang is right: It's not a good idea to set up default initial
ethernet addresses for a board, even though they belong to the local
range.
This will change the failure mode from "IT manager screams at you for
using duplicate ethernet addresses" to a nice error message explaining
that the ethernet address hasn't been set properly.
Found a bug in the way the DHCP Request packet is built, where the IP address
that is offered by the server is bound to prematurely. This patch is a fix of
that bug where the IP address offered by the DHCP server is not used until
