The idea is taken from the mfgtool support in the NXP U-Boot: http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/?h=imx_v2016.03_4.1.15_2.0.0_ga&id=a352ed3c5184b95c4c9f7468f5fbb5f43de5e412 Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Tested-by: Fabio Estevam <fabio.estevam@nxp.com> Reviewed-by: Eric Nelson <eric@nelint.com>
