* Cleanup lowboot code for MPC5200
* Minor code cleanup (coding style)
* Patch by Reinhard Meyer, 30 Dec 2003:
- cpu/mpc5xxx/fec.c: added CONFIG_PHY_ADDR, added CONFIG_PHY_TYPE,
- added CONFIG_PHY_ADDR to include/configs/IceCube.h,
- turned debug print of PHY registers into a function (called in two places)
- added support for EMK MPC5200 based modules
* Fix MPC8xx PLPRCR_MFD_SHIFT typo
* Add support for TQM866M modules
* Fixes for TQM855M with 4 MB flash (Am29DL163 = _no_ mirror bit flash)
* Fix a few compiler warnings
