Currently in-system update means to write an arbitrary file to an arbitrary device. There is no sanity check if the flashed image is of the right type or will fit onto the device. Furthermore some SoCs need a special preparation step for their images before flashing them. This adds a barebox in-system update infrastructure. Boards can register update handlers which know how to make the board bootable. The available handlers can be listed to be able to select one, different force levels give the user the chance to know it better. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
