Subject: [PATCH 07/13] environment: stub out environment API for PBL
Date: Wed, 16 Oct 2024 11:01:44 +0200	[thread overview]
Message-ID: <20241016090150.3963002-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20241016090150.3963002-1-a.fatoum@pengutronix.de>

To optimize out calls to undefined functions in PBL at compile-time
instead of link time, let's define stubs for the functions that
are referenced in obj-pbl-y files, but inside function sections
that are ultimately unreferenced.
