Subject: [PATCH 07/12] hw/arm/bcm2836: Introduce BCM283XClass::core_count
Date: Sat, 15 Feb 2020 20:15:38 +0100	[thread overview]
Message-ID: <20200215191543.3235-8-f4bug@amsat.org> (raw)
In-Reply-To: <20200215191543.3235-1-f4bug@amsat.org>

The BCM2835 has only one core. Introduce the core_count field to
be able to use values different than BCM283X_NCPUS (4).
