Subject: [PATCH v2 1/3] ppc: define sync_caches_for_execution only for MPC85xx
Date: Tue, 14 Apr 2026 10:06:28 +0200 [thread overview]
Message-ID: <20260414080652.397582-1-a.fatoum@pengutronix.de> (raw)
From: Ahmad Fatoum <a.fatoum@barebox.org>
In preparation for adding a call to sync_caches_for_execution() into
common code, make sure PowerPC configurations without an out-of-line
definition fallback to the inline no-op definition.
