From 2996e2dcc0454207b4bf6248d034aead4ac54591 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 6 Jan 2012 12:14:42 +0000 Subject: [PATCH] tegra2: Add support for Compal Paz00 (Toshiba AC100) The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook derived from the NVIDIA Tegra Harmony reference board. It ships with Android, but is often repurposed to run Linux. This patch adds just enough support to get a U-Boot serial console, and the ability access built-in eMMC and the external SD slot. v2: * Rebased on latest HEAD, incorporated changes made to other board files. * Moved board files from board/nvidia to board/compal. * Switched to correct odmdata value. This required add the previous patch to fix U-Boot's interpretation of the odmdata RAM size field. * Removed nvmem= from default Linux kernel command-line; no drivers use the reserved memory yet, so there's no point reserving it.
