- basically follow mini_armv7a_neon with goldfish HALs
- requires kernel update with fuse support (not updated yet!)
- will re-use goldfish kernel, which means hardware name will be still be goldfish
- init.mini....rc will be copied to init.goldfish.rc, and is based on init.goldfish.rc with addition for sdcard emulation
