Subject: [PATCH 0/4] Kbuild: replace legacy <config.h> mechanism
Date: Fri, 28 Nov 2025 11:58:40 +0100 [thread overview]
Message-ID: <20251128110005.3336591-1-a.fatoum@pengutronix.de> (raw)
Generation per-board config.h headers is a left-over from times long
past. For most boards it's no longer possible anyway due to multi-image
suppot, but for legacy boards that still use it, let's switch away
existing users from this magic and remove it.
Ahmad Fatoum (4):
openrisc: drop <config.h> usage
ARM: drop <config.h> usage
ppc: drop <config.h> usage
treewide: drop last remnants of <config.h>
