Subject: [PATCH v2 2/2] Platform/RaspberryPi: Increase genet dma window
Date: Tue, 11 May 2021 17:37:34 -0500 [thread overview]
Message-ID: <20210511223734.864455-3-jeremy.linton@arm.com> (raw)
In-Reply-To: <20210511223734.864455-1-jeremy.linton@arm.com>
The genet is capable of addressing the entire memory space
on the RPI4. Lets allow it to dma into those regions.
This solves intermittent issues with grub/etc being able
to communicate when the 3G limit is lifted on 8G boards.
