17 * Define master clock frequency. This is essentially done at config
18 * time now. No point enumerating dozens of possible clock options
19 * here. Also the peripheral clock (bus clock) divide ratio is set

23 #define MCF_CLK CONFIG_CLOCK_FREQ
24 #define MCF_BUSCLK (CONFIG_CLOCK_FREQ / CONFIG_CLOCK_DIV)
26 #error "Don't know what your ColdFire CPU clock frequency is??"
30 * Define the processor internal peripherals base address.
32 * The majority of ColdFire parts use an MBAR register to set
33 * the base address. Some have an IPSBAR register instead, and it
34 * has slightly different rules on its size and alignment. Some
35 * parts have fixed addresses and the internal peripherals cannot
36 * be relocated in the CPU address space.
38 * The value of MBAR or IPSBAR is config time selectable, we no
39 * longer hard define it here. No MBAR or IPSBAR will be defined if
40 * this part has a fixed peripheral address map.
