Subject: [PATCH v4 4/8] ppc/e500: Use start-powered-off CPUState property
Date: Tue, 18 Aug 2020 00:33:19 -0300	[thread overview]
Message-ID: <20200818033323.336912-5-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20200818033323.336912-1-bauerman@linux.ibm.com>

Instead of setting CPUState::halted to 1 in ppce500_cpu_reset_sec(), use
the start-powered-off property which makes cpu_common_reset() initialize it
to 1 in common code.

Also change creation of CPU object from cpu_create() to object_new() and
qdev_realize() because cpu_create() realizes the CPU and it's not possible
to set a property after the object is realized.
