On these you can disable clock setting. On some traditional 68K parts, and on all ColdFire parts you need to set the appropriate CPU clock frequency. On these devices many of the onboard peripherals derive their timing from the master CPU clock frequency.config CLOCK_FREQ int "Set the core clock frequency" default "66666666" depends on CLOCK_SET help Define the CPU clock frequency in use. This is the core clock frequency, it may or may not be the same as the external clock crystal fitted to your board. Some processors have an internal PLL and can have their frequency programmed at run time, others use internal dividers. In general the kernel won't setup a PLL if it is fitted (there are some exceptions). This value will be specific to the exact CPU that you are using.config CLOCK_DIV int "Set the core/bus clock divide ratio" default "1" depends on CLOCK_SET help On many SoC style CPUs the master CPU clock is also used to drive on-chip peripherals. The clock that is distributed to these peripherals is sometimes a fixed ratio of the master clock frequency. If so then set this to the divider ratio of the master clock to the peripheral clock. If not sure then select 1.config OLDMASK bool "Old mask 5307 (1H55J) silicon" depends on M5307 help Build support for the older revision ColdFire 5307 silicon.
