Subject: [PATCH] arm_gic: Extract headers hw/intc/arm_gic{,_common}.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Rename NCPU to GIC_NCPU and move GICState away from gic_internal.h.
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
Signed-off-by: Andreas Färber <afaerber@suse.de>
(cherry picked from commit 83728796ad3f2ce7d6162c1cb894528b12915646)
