* Add a variable called UBOOT_LOCALVERSION which when set will
  place a version string in the .scmversion file of the u-boot
  sources.  This string will be picked up by the u-boot Makefile
  and will be appended to the u-boot version.  This is done to
  make it easier to identify what revision of the u-boot sources
  are being run.  For example you can use a setting like the
  following to add the short commit id to the u-boot version

UBOOT_LOCALVERSION = "-g${@d.getVar('SRCPV', True).partition('+')[2][0:7]}"
