Subject: [PATCH v2 01/11] kvx: dma: Remove arch dma_map/unmap_single
Date: Mon, 17 Jan 2022 23:19:07 +0100	[thread overview]
Message-ID: <20220117221917.26970-2-jmaselbas@kalray.eu> (raw)
In-Reply-To: <20220117221917.26970-1-jmaselbas@kalray.eu>

Since dma_map/unmap_single functions have been moved to common, barebox
doesn't compile for kvx anymore. The original functions were doing some
magic to support 32bits dma buffer addresses. The original behavior can
be replaced by a device-tree dma-range property.

Fixes: 3f975f810 ("dma: move dma_map/unmap_single from ARM to common code")
Signed-off-by: Jules Maselbas <jmaselbas@kalray.eu>
