[PATCH 11/19] ARM: S5PC1XX: add S5PC110 cpu initialization code
Marek Szyprowski

Wed Nov 18 08:33:06 EST 2009
From: Kyungmin Park <kyungmin.park at samsung.com>
Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds CPU initialization code for S5PC110 sub-platform.
