> Add a new file init.h with the prototype for arch_cpu_init
> Add a prototype for mach_cpu_init() to avoid a warning:
> no previous prototype for ‘mach_cpu_init’
>
> It is a first step to move all the functions prototype
> used during U-Boot initialization (board_f.c / board_r.c)
> from common.h to init.h

> Changes in v2:
