[PATCH v2 10/12] hw/arm/raspi: List models creatable by the generic 'raspi' machine
All the following models can be created (with different RAM size):
$ qemu-system-aarch64 -M raspi
qemu-system-aarch64: Missing model, try -M raspi,model=help
$ qemu-system-aarch64 -M raspi,model=help
Available models (processor):
- A (BCM2835)
- B (BCM2835)
- A+ (BCM2835)
- B+ (BCM2835)
- 2B (BCM2836)
- CM1 (BCM2835)
- 3B (BCM2837)
- Zero (BCM2835)
- CM3 (BCM2837)
- ZeroW (BCM2835)
- 3B+ (BCM2837)
- 3A+ (BCM2837)
- CM3+ (BCM2837)
- 4B (BCM2838)
