Subject: [PATCH 11/19] ARM: mmp: map the PGU as well
Date: Fri, 9 Aug 2019 11:31:50 +0200 [thread overview]
Message-ID: <20190809093158.7969-12-lkundrak@v3.sk> (raw)
In-Reply-To: <20190809093158.7969-1-lkundrak@v3.sk>
The MMP2 and later includes a system control unit in this area. We'll need
that to initialize the secondary core on MMP3.
Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>
