Cortex-A8 (OMAP3) part

Acked-by: Dirk Behme <dirk.behme@googlemail.com>

Just a minor _question_ for an other board below:

Would encapsulating this new arch_cpu_init() with an additional 
CONFIG_ARCH_CPU_INIT, e.g.

#if defined(CONFIG_ARCH_CPU_INIT)
int arch_cpu_init (void)
{

(like below) help to avoid issues if cpu/s3c44b0/cpu.c would be 
compiled without CONFIG_ARCH_CPU_INIT enabled?
