[Qemu-devel] [PATCH 00/12] QOM'ify SuperH CPU and SH7750 SoC

[Andreas Färber]

Hello,

Based on qom-cpu v4 and object_class_get_list() v2, this series converts
the SuperH CPU to QOM.

The SH7750 SoC code invited to do some cleanups, making use of the SuperHCPU,
so I've QOM'ified the SoC and added the CPU as a link<SuperHCPU> for now.

I'm not so happy about the link construct, so it may need to be redone
as a SysBus device with qdev properties - long-term I'd like to have a
"system-on-chip" type derived from TYPE_DEVICE. Deriving it from
TYPE_SYS_BUS_DEVICE might make for a better v2.

Patch 1 does the actual CPU QOM'ification, introducing SuperHCPU.

Patch 2 is a bugfix noticed during QOM'ification.

Patches 3-11 start using QOM SuperHCPU in place of CPUSH4State.

Patch 12 QOM'ifies the SH7750 SoC. Optional.
