[U-Boot-Users] [Patch] U-Boot-V2: Introduce CONFIG_ARCH_HAS_INIT_LOWLEVEL

[Menon, Nishanth]

Based on http://sourceforge.net/mailarchive/forum.php?thread_name=20080508151609.GB9467%40pengutronix.de&forum_name=u-boot-users
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.
