Instead of set rotation in framebuffer, Android already supports H/W
rotation in 90 or 270 degree, but it does not support 180 degree
though.

I guess you probably can try to add 180 degree support - please look
at the file services/surfaceflinger/SurfaceFlinger.cpp,
GraphicPlane::setDisplayHardware() reads prop 'ro.sf.hwrotation' and
configures the orientation. you can try to add
'ISurfaceComposer::eOrientation180' for ro.sf.hwrotation=180.
