From cdce889959c611876690a9f0a3c7ed9aa46189c4 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 6 Aug 2013 22:52:25 -0700 Subject: [PATCH] tegra: Avoid using I2C prior to relocation Tegra recently moved to the new I2C framework, which sets up I2C prior to relocation, and prior to calling i2c_init_board(). This causes a crash on Tegra boards.
