From a6c7b461814028870697182d19383ef5b370c257 Mon Sep 17 00:00:00 2001 From: Allen Martin Date: Thu, 4 Dec 2014 06:36:30 -0700 Subject: ARM: tegra: Add support for nyan-big board Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but it has a different panel, the sdcard cd and wp sense are flipped, and it has a different revision of the AS3722 PMIC. This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA Tegra K1, 2GB). The display is not currently supported, so it should boot on other nyan-based Chromebooks also, but only the device tree for nyan-big is provided here. The device tree file is from Linux but with features removed which are unlikely to be supported in U-Boot soon (regulators, pinmux). Also the addresses are updated to 32-bit.
