30 * Two valid values are:
34 * Most PCI cards are still 33Mhz, so in the presence of PCI, 33MHz
35 * is likely the desired value here, so that is now the default.
36 * The board, however, can run at 66MHz. In any event, this value
37 * must match the settings of some switches. Details can be found
38 * in the README.mpc85xxads.
42 * These can be toggled for performance analysis, otherwise use default.
