[PATCH v2 10/25] image: Move common image code to image_board and command
Simon Glass
sjg at chromium.org
Fri Nov 4 23:48:28 CET 2022
We should use the cmd/ directory for commands rather than for common code
used elsewhere in U-Boot. Move the common 'source' code into
image-board.c to achieve this.
The image_source_script() function needs to call run_command_list() so
seems to belong better in the command library. Move and rename it.
