| * SDRAM refresh and other timings. |

| * 25 * 16 / 3 = 133 MHz |
| * 25 MHz because the oscillator also feeds the ether chip. |
| * CONFIG_CLKIN_HZ is 25 MHz written in Hz |
| * CLKIN_HALF controls the DF bit in PLL_CTL |
| * 0 = CLKIN 1 = CLKIN / 2 |
| * PLL_BYPASS controls the BYPASS bit in PLL_CTL |
| * 0 = do not bypass 1 = bypass PLL |
| * VCO_MULT = MSEL (multiplier) in PLL_CTL |
| * Values can range from 0-63 (where 0 means 64) |
| * CCLK_DIV = core clock divider (1, 2, 4, or 8 ONLY) |
