This page provides examples of the sorts of routines that are frequently defined in a board's board.c file. We can break those routines up into routines invoked from:

• common/board_f.c
• common/board_r.c

__weak int arch_cpu_init(void)
{
        return 0;
}

__weak int mach_cpu_init(void)
{
        return 0;
}
