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 support for SMDKC110 evaluation board. The board can be
obtained from Meritech (http://www.meritech.co.kr).
