[PATCH 08/29] bootm: Move boot_get_kernel() higher in the file
Simon Glass
sjg at chromium.org
Sun Nov 12 01:08:53 CET 2023
Move this code and image_get_kernel() higher in the file to avoid the
need for a forward declaration.
No attempt is made to remove #ifdefs or adjust the code in any other
way.
