Subject: [PATCH v3 8/8] Hack: Pretend we have PSCI 1.2
Date: Wed, 20 Aug 2025 11:29:50 +0100	[thread overview]
Message-ID: <20250820102950.175065-9-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20250820102950.175065-1-Jonathan.Cameron@huawei.com>

Need to update QEMU to PSCI 1.2. In meantime lie.
This is just here to aid testing, not for review!
