Allwinner A83TDevBoard

This is a limited edition product verification board that is used here for the purpose of mainline support of the A83T SoC.

= Identification =

On the front of the board, the following is printed: H8_HOMELET_PROTOTYPE_V2_0 20141015 L4

The PCB has the following silkscreened on it: TEAN-E120399 94V-OML1

These markings do not have specific significance to the A83T since this is a product verification board.

= Sunxi support =

Current status
There is ongoing discussion at https://groups.google.com/forum/#!topic/linux-sunxi/_woM2vJmcuc regarding the mainline support of the SoC in this board.
