Subject: [PATCH 3/7] dma-mapping: allow using the global coherent pool for !ARM
Date: Mon, 12 Jul 2021 08:17:00 +0200 [thread overview]
Message-ID: <20210712061704.4162464-4-hch@lst.de> (raw)
In-Reply-To: <20210712061704.4162464-1-hch@lst.de>
Switch an ifdef so that the global coherent pool is initialized for
any architecture that selects the DMA_GLOBAL_POOL symbol insted of
hardcoding ARM.
