[PATCH v3 37/46] bootmeth: Refactor to put options in a common file

[Simon Glass]

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.
