But as I pointed out apparently other boards need something like that too:

.globl reset_cpu
reset_cpu:
...
# ifdef CONFIG_TRAB
	bl	disable_vfd
# endif

So reset is cpu (better SoC) specific and might even be board specific.

Of coures we can clobber cpu/arm920t/start.S with reset code for every cpu, SoC 
and board ... adding loads of nice #ifdef's ;-)
