Title:
  support custom u-boot config

Status in “flash-kernel” package in Ubuntu:
  Fix Released

Bug description:
  An upcoming platform (keystone2) has a need to be able to set a u-boot
  environment variable, but the appropriate setting needs to be
  controlled by software running in Ubuntu (pre-boot memory
  configuration changes). Right now bootscripts provided by flash-kernel
  are immutable - the end user can't go in and add settings without
  creating a custom flash-kernel package. We should provide packages and
  users with an interface to add custom settings to platform
  bootscripts.

  [Impact]
  Users of the keystone2 platform will have no supported way to configure u-boot settings necessary to make use of features of their hardware.
  [Test Case]
  echo "setenv foo bar" > /etc/flash-kernel/ubootenv.d/foo
  sudo flash-kernel
  Confirm that /boot/boot.scr includes the "setenv foo bar" command
  [Regression Risk]
  The proposed change requires explicit opt-in support for a given platform, and currently we're only adding it to not-yet-released platforms.
