Subject: target-sparc: Let cpu_sparc_init() return SPARCCPU
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4039^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e59be77a5b88510ceca87335ee9f241ded566ae2;p=sdk%2Femulator%2Fqemu.git

target-sparc: Let cpu_sparc_init() return SPARCCPU

Make include paths for cpu-qom.h consistent, so that SPARCCPU can be
used in cpu.h.

Turn cpu_init macro into a static inline function returning
CPUSPARCState for backwards compatibility.
