Subject: [PATCH 2/4] soc/fsl/qbman: Add 64 bit DMA addressing requirement to QBMan
Date: Thu, 20 Sep 2018 18:06:49 +0300 [thread overview]
Message-ID: <1537456011-10769-3-git-send-email-madalin.bucur@nxp.com> (raw)
In-Reply-To: <1537456011-10769-1-git-send-email-madalin.bucur@nxp.com>
From: Roy Pledge <roy.pledge@nxp.com>
The QBMan block is memory mapped on SoCs above a 32 bit (4 Gigabyte)
boundary so enabling 64 bit DMA addressing is needed for QBMan to
be usable.
