This results in the following compile time error: CC arch/m68k/kernel/asm-offsets.s In file included from ./arch/m68k/include/asm/timex.h:14:0, from include/linux/timex.h:65, from include/linux/sched.h:19, from arch/m68k/kernel/asm-offsets.c:14: ./arch/m68k/include/asm/coldfire.h:25:2: error: #error "Don't know what your ColdFire CPU clock frequency is??" Remove CONFIG_CLOCK_SELECT completely and always enable CONFIG_CLOCK_FREQ for ColdFire.
