Based on http://sourceforge.net/mailarchive/forum.php?thread_name=20080508151609.GB94... I am splitting the patches into two. This is the first one for introducing arch specific config.
This introduces CONFIG_ARCH_HAS_INIT_LOWLEVEL which can be enabled for SOC designs which require additional initialization.
