H8Homlet Proto v2.0 Board is A83T Dev Board by Allwinner.
It has UART, ethernet, USB, HDMI, etc ports on it.

It's name is confusing, Its A83T board however,"H8_HOMLET_PROTO_V2"
printed on board.

A83T patches are tested on this board.
It has UART, ethernet, USB, HDMI, etc ports on it.

For FEL mode it needs USB A-A(Male) cable. I used uart0 which
is multiplexed to microsd pins PF2 and PF4.
Is there no other UART on the device?

we probably want to mention the h8 in here too, and the v2 is enough.
