It has under a different name i have yet to make it work though.

Thank you for testing!!

I will be fixing the issues brought up thx for the input.
The issues are DRAM using the device tree.
Clocks in the device tree.
Pinmuxing doesn't work for device tree.
And SPI boot.

Most of the issues im encountering stem from SUNXI being a mix of DT and 
non-DT code. which is frustrating to work with.

Thanks,
	Jesse Taube.
