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

2008-02-20 Thread Mike Nuss
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.
