hw/arm/bcm2836: Only provide "enabled-cpus" property to multicore SoCs
It makes no sense to set enabled-cpus=0 on single core SoCs. Reviewed-by: Luc Michel <luc.michel@greensocs.com> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-id: 20201024170127.3592182-5-f4bug@amsat.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
