There are many other parameters beyond the CPU clock that could be

On PPC440EPx without a bootstrap I2C EEPROM, the PLL can be reconfigured
after startup to change the speed of the clocks. This patch adds the
option CFG_PLL_RECONFIG. If this option is set to 667, the CPU
initialization code will reconfigure the PLL to run the system with a CPU
frequency of 667MHz
On PPC440EPx without a bootstrap I2C EEPROM, the PLL can be reconfigured after
startup in order to change the speed of the clocks. This patch adds the option
CONFIG_667MHZ. If set, it will set the clocks to run at full speed on a 667MHz
PPC440EPx without the need for an external EEPROM.
