Subject: strongarm: QOM cast cleanup for StrongARMPPCInfo
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~1499^2~116
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c71e67329188ee1081de53ef685e627c6e99cc87;p=sdk%2Femulator%2Fqemu.git

strongarm: QOM cast cleanup for StrongARMPPCInfo

Introduce a type constant, use QOM casts, rename the parent field and
prepare for QOM realize.
