I have one tablet , I see now  that seems to be CORTEX A9 Dual Core ,
also an popular low cost arm,  but supposed that is an Allwinner sunxi.
I'd like to know , how I a boot there, if I can have dual boot to keep
android flavor etc, where I can get this kind of documentation ?
regarding install on it, Fedora arm .
