DDR2 memory may be used at 133 MHz provided that the memory components are specified for operation at this frequency.
Clocking
19.2
RCWL[COREPLL] selects the ratio between the internal coherent system bus clock (csb_clk) and the e300
core clock (core_clk).

CFG_CLKIN_DIV doubles csb_clk if set high.
CLKIN is the input clock in host mode; PCI_CLK is the input clock in agent mode.
