Hi

To make sure headers don't create conflicts, guards are added to all of them.

But the guard needs to be correct: e.g. https://review.coreboot.org/c/coreboot/+/64360/2

Most compilers implement '#pragma once ' as an alternative.

Should we use this instead across the tree, as it is less error prone and less code?

Sidenote: clang warns about wrong header guards.
https://review.coreboot.org/c/coreboot/+/62173/23 hooks up clang to our CI for some platforms ;-).

Kind regards
