[PATCH 3/5] allarch/lib: Convert core of allarch code into a function

Richard Purdie
2026-03-14T09:48:14Z

We need to call the functionality in allarch.bbclass from other contexts
and the current conditionals are problematic enough without further changes
confusing things. Move the code to a funtion in oe.utils so we can call
it as needed.
