Subject: target-sparc: QOM'ify CPU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Embed CPUSPARCState as first member of SPARCCPU.
Drop cpu_sparc_close() in favor of object_delete() and a finalizer.
Let cpu_state_reset() call cpu_reset().

Make TYPE_SPARC_CPU non-abstract for now.
Distinguish between "sparc-cpu" and "sparc64-cpu".
