30 * CLOCK SETTINGS CAVEAT
31 * You CANNOT just change the clock settings, esp. the SCLK.
32 * The SDRAM timing, SPI baud, and the serial UART baud
33 * use SCLK frequency to set their own frequencies. Therefore,
34 * if you change the SCLK_DIV, you may also have to adjust
35 * SDRAM refresh and other timings.
36 * --------------------------------------------------------------
37 * CCLK = (CLKIN * VCO_MULT) / CCLK_DIV
38 * 25 * 8 / 1 = 200 MHz
39 * 25 * 16 / 1 = 400 MHz
40 * 25 * 24 / 1 = 600 MHz
41 * SCLK = (CLKIN * VCO_MULT) / SCLK_DIV
42 * 25 * 8 / 2 = 100 MHz
43 * 25 * 24 / 6 = 100 MHz
44 * 25 * 24 / 5 = 120 MHz
45 * 25 * 16 / 3 = 133 MHz
46 * 25 MHz because the oscillator also feeds the ether chip.
47 * CONFIG_CLKIN_HZ is 25 MHz written in Hz
48 * CLKIN_HALF controls the DF bit in PLL_CTL
49 * 0 = CLKIN 1 = CLKIN / 2
50 * PLL_BYPASS controls the BYPASS bit in PLL_CTL
51 * 0 = do not bypass 1 = bypass PLL
52 * VCO_MULT = MSEL (multiplier) in PLL_CTL
53 * Values can range from 0-63 (where 0 means 64)
54 * CCLK_DIV = core clock divider (1, 2, 4, or 8 ONLY)
55 * SCLK_DIV = system clock divider, 1 to 15
