Subject: [RFC PATCH 1/4] hw/intc: don't bail out gicv3 model init for revision 4
Date: Sun, 24 Jan 2021 02:53:03 +0000	[thread overview]
Message-ID: <20210124025306.3949-2-leif@nuviainc.com> (raw)
In-Reply-To: <20210124025306.3949-1-leif@nuviainc.com>

As a first step towards GICv4 compatibility, add support for gic revision 4
to GICv3 driver (i.e. don't bail out if revision 4 is encountered).
