Subject: [edk2-platforms][PATCH 5/6] Platform/RPi/AcpiTables: Move GPU devices into a separate ASL file
Date: Thu, 26 Mar 2020 11:53:21 +0000 [thread overview]
Message-ID: <20200326115322.2880-6-pete@akeo.ie> (raw)
In-Reply-To: <20200326115322.2880-1-pete@akeo.ie>
From: Andrei Warkentin <andrey.warkentin@gmail.com>
In order to describe the DMA constraints of legacy devices behind
the Raspberry Pi GPU/VideoCore, we move them into their own separate
ASL file.
This is a straight copy of the existing content from Dsdt.asl, with
no alteration, so that the changes applied in the next patch are
made more obvious.
