[PATCH v2 33/41] bootmeth: Refactor to put options in a common file
Simon Glass
sjg at chromium.org
Wed Dec 4 00:45:51 CET 2024
The fallback feature is implemented for extlinux but not for PXE. Move
the code into common files so we can keep both pieces in sync.
Tidy up the comment for set_property() while we are here, fixing the
return value and some missing hyphens.
