  21 Android (www.android.com) is an open source operating system for mobile devices.
  22 This document describes configurations needed to run the Android framework on
  23 top of the Linux kernel.
  24
  25 To see a working defconfig look at msm_defconfig or goldfish_defconfig
  26 which can be found at http://android.git.kernel.org in kernel/common.git
  27 and kernel/msm.git

  30 1.1 Required enabled config options
  31 -----------------------------------
  32 After building a standard defconfig, ensure that these options are enabled in
  33 your .config or defconfig if they are not already. Based off the msm_defconfig.
  34 You should keep the rest of the default options enabled in the defconfig
  35 unless you know what you are doing.
