From df3443dfa449ad02bef8ddf6e2c90a6fd9394fc9 Mon Sep 17 00:00:00 2001 From: Bryan Wu Date: Tue, 24 Jun 2014 11:45:29 +0900 Subject: ARM: tegra: Disable VPR On Tegra114 and Tegra124 platforms, certain display-related registers cannot be accessed unless the VPR registers are programmed. For bootloader, we probably don't care about VPR, so we disable it (which counts as programming it, and allows those display-related registers to be accessed). This patch is based on the commit 5f499646c83ba08079f3fdff6591f638a0ce4c0c in Chromium OS U-Boot project.
