Hi Dietmar,

Thanks for sharing this.
Please include the sunxi maintainers in your email, for improved
response time.

Please note that patches need your Signed-off-by:, to be eligible for
inclusion.

In general we don't take DT patches straight to U-Boot, they need to go
via the kernel tree first, then get synced back from time to time.
I just sent an update for all A64s, that should fix your network problem
already.

For the USB part: The sunxi Wiki is a bit controversial on this topic
(talking about a hub at some point), so can you clarify the USB
situation on the board?
Is controller 0 connected to the micro-USB socket, and the two type-A
receptables are connected via a hub?
Or is it like the Pine64: the two type-A receptables are connected to
controller 0 and 1, and the micro-USB is just for power?

If it is the latter, I wonder how this patch works for you? I need
another U-Boot patch [1] (which I want to send out shortly) to actually
enable this port 0 as a host port, and also rely on a DT change (now
merged in mainline Linux).

Cheers,
Andre
