Subject: target-lm32: Let cpu_lm32_init() return LM32CPU
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4039^2~67
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0347d689f7339ec925f3a2dcb2c3bcad4d6ef315;p=sdk%2Femulator%2Fqemu.git

target-lm32: Let cpu_lm32_init() return LM32CPU

Make the include paths for cpu-qom.h consistent to allow using LM32CPU
in cpu.h.

Turn cpu_init macro into a static inline function returning CPULM32State
for backwards compatibility.
