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_HOMLET_PROTO_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.

BSP
The repository at https://github.com/allwinner-zh/bootloader contains
 * BSP for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/bsp/bsp_for_a83

Manual build

 * For building U-Boot, use the  target.
 * The .fex file can be found in sunxi-boards as

Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline U-Boot, use the 'h8_homlet_v2_defconfig' target.

The reference source code from Allwinner is at https://github.com/allwinner-zh/bootloader contains
 * Boot 0 source code for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/boot0
 * U-boot 2011.09 for the A83T, https://github.com/allwinner-zh/bootloader/tree/master/u-boot-2011.09

Mainline kernel
Basic support is available in mainline kernel for A83T.

Use sun8i-a83t-allwinner-h8homlet-v2.dtb device-tree tree binary.

There is a 3.4 source tree for the A83T at https://github.com/allwinner-zh/linux-3.4-sunxi/tree/A83T
