From 6dad573c8689b79bb4aa615811a10f44e7d8c809 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 6 Aug 2014 15:27:12 -0500 Subject: [PATCH] tegra132: move common bootblock init into SoC code The current 2 boards were setting up clocks and enabling peripherals that apply to the SoC generically. Therefore, move the common pieces into the SoC code. BUG=chrome-os-partner:31105 BRANCH=None TEST=Built and booted through depthcharge on ryu.
