0. Getting sources:
-----------------

git checkout -b android-msm-2.6.29 origin/android-msm-2.6.29


1. Android
==========

Android (www.android.com) is an open source operating system for mobile devices.
This document describes configurations needed to run the Android framework on
top of the Linux kernel.

To see a working defconfig look at msm_defconfig or goldfish_defconfig
which can be found at http://android.git.kernel.org in kernel/common.git
and kernel/msm.git

msm_defconfig should work on qualcomm reference design, HTC Magic and G1/ADP1.

1.1 Required enabled config options
-----------------------------------
After building a standard defconfig, ensure that these options are enabled in
your .config or defconfig if they are not already. Based off the msm_defconfig.
You should keep the rest of the default options enabled in the defconfig
unless you know what you are doing.
