Subject: [PATCH 1/3] Platform/RaspberryPi/Acpitables: Further lower the DMA zone
Date: Fri,  8 Jan 2021 00:16:21 -0600	[thread overview]
Message-ID: <20210108061623.1721817-2-jeremy.linton@arm.com> (raw)
In-Reply-To: <20210108061623.1721817-1-jeremy.linton@arm.com>

We are going to add a _DMA() for the new controller, but
it won't work right with the linux driver unless we lower
the DMA zone again.
