* 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
