[Qemu-devel] [PATCH v5 0/6] Add a valid_cpu_types property |

There are numorous QEMU machines that only have a single or a handful of
valid CPU options. To simplyfy the management of specificying which CPU
is/isn't valid let's create a property that can be set in the machine
init. We can then check to see if the user supplied CPU is in that list
or not.
I have added the valid_cpu_types for some ARM machines only at the
moment.
Here is what specifying the CPUs looks like now:
$ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf
-nographic -cpu "cortex-m3" -S
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) info cpus
* CPU #0: thread_id=24175
(qemu) q
$ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf
-nographic -cpu "cortex-m4" -S
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) q
$ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf
-nographic -cpu "cortex-m5" -S
qemu-system-aarch64: unable to find CPU model 'cortex-m5'
$ aarch64-softmmu/qemu-system-aarch64 -M netduino2 -kernel ./u-boot.elf
-nographic -cpu "cortex-a9" -S
qemu-system-aarch64: Invalid CPU type: cortex-a9-arm-cpu
The valid models are: cortex-m3, cortex-m4
V5:
- Use cpu_model instead of cpu_type
V4:
- Rebase
- Remove spaces
V3:
- Make the varialbes static
V2:
- Rebase
- Reorder patches
- Add a Raspberry Pi 2 CPU fix
V1:
- Small fixes to prepare a series instead of RFC
- Add commit messages for the commits
- Expand the machine support to ARM machines
RFC v2:
- Rebase on Igor's work
- Use more QEMUisms inside the code
- List the supported machines in a NULL terminated array
Alistair Francis (6):
machine: Convert the valid cpu types to use cpu_model
netduino2: Specify the valid CPUs
bcm2836: Use the Cortex-A7 instead of Cortex-A15
raspi: Specify the valid CPUs
xlnx-zcu102: Specify the valid CPUs
xilinx_zynq: Specify the valid CPUs
