The current support for updating variables in a binary is hard-coded to work with U-Boot: - It assumes the image starts at __image_copy_start - It uses the existing U-Boot-specific entry types It is useful for other projects to use these feature. Add properties to enable writing symbols for any blob, a way of specifying the base symbol and a way of providing the ELF filename to allow symbol lookup to take place. With this it is possible to update a Zephyr image, such as zephyr.bin after it has been built. Signed-off-by: Simon Glass <sjg@chromium.org>
