==========
Android () 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 in kernel/common.git
and kernel/msm.git
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.
