This is building passion's memo
IMPORTANT: I don't know it's work or not. OK, it's work fine!

• Get Android Source Code
• Android Git Repositories
• Compile CyanogenMod for Passion

Quick resolved linking error building 'gingerbread' for passion.
Camera HAL has been changed since gingerbread for multi-camera support.

• undefined reference to 'HAL_openCameraHardware'
• undefined reference to 'HAL_getCameraInfo'

1. mkdir -p gingerbread/myapp/libpassioncameraif
2. copy cameraif.cpp and Android.mk.
3. cd gingerbread/myapp/libpassioncameraif
4. mm
5. cd gingerbread/frameworks/base/services/camera/libcameraservice
