From 72af2fc8504daccd2f8ae2459e3e225e9c2cc512 Mon Sep 17 00:00:00 2001 From: Inderpal Singh Date: Thu, 4 Apr 2013 23:09:19 +0000 Subject: exynos: move tzpc_init to armv7/exynos tzpc_init is common for all exynos5 boards, hence move it to armv7/exynos so that all other boards can use it. Also update the smdk5250 Makefile and config file.
