Subject: [PATCH 07/08] PCI: rcar: Enable BOUNCE in case of HIGHMEM
Date: Thu, 13 Feb 2014 12:04:13 +0900 [thread overview]
Message-ID: <20140213030413.10398.20246.sendpatchset@w520> (raw)
In-Reply-To: <20140213030302.10398.37322.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Select BOUNCE in case of HIGHMEM to enable bounce buffers in
the block layer. Without this patch the DMABOUNCE code will
error out due to lack of HIGHMEM support, and without DMABOUNCE
there will be silent errors.

Say Y here if you want internal PCI support on R-Car Gen2 SoC.
There are 3 internal PCI controllers available with a single
