made CONFIG_SILENT_CONSOLE usable on all architectures * Disable date command on TQM866M - there is no RTC on MPC866
see doc/README.MPC866 for details; implement workaround for "SIU4" and "SIU9" silicon bugs on MPC866; calculate CPU clock frequency from PLL register values. * Add support for 128 MB RAM on TQM8xxL/M modules
