Subject: [PATCH v6 12/17] firmware: arm_scmi: Make shmem support optional for transports
Date: Mon, 12 Jul 2021 15:18:28 +0100 [thread overview]
Message-ID: <20210712141833.6628-13-cristian.marussi@arm.com> (raw)
In-Reply-To: <20210712141833.6628-1-cristian.marussi@arm.com>
From: Igor Skalkin <igor.skalkin@opensynergy.com>
Upcoming new SCMI transports won't need any kind of shared memory support.
Compile shmem.c only if a shmem based transport is selected.
