Eva Wu from Allwinner marketing sent me the new logo for A80. There is no much info about it yet, but it will be 8 core (4xCortex-A15 and 4xCortexA7) and Allwinner is working now on it. Probably it will have 8-16 GPU co-processors too, we hope these to be MALI but there are great chances these to be PowerVR like A31, Eva is silent on this.

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 MANUFACTURER_DEVICE target.
- The .fex file can be found in sunxi-boards as MANUFACTURER_DEVICE.fex
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.

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
The following table is a comparison of the A83T SoC to other SoCs from the A-series.
| Module | Description |
|---|---|
| CPU | Cortex-A7 MP4 in 2 clusters, the MCPM is more likely as the A80 |
