* 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
