A23

Allwinner A23 (sun8i) SoC features a Dual-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. It is a lower power cut-down version of the A20.

=Overview=

Currently, there is no sunxi support available, as we are only now getting the devices and since only kernel code has been made available so far.

No code U-Boot is available, even though Allwinner promised this for somewhere in the 2nd week of March 2014. Allwinner is once again in violation of the GPLv2.

No livesuite tool has been made available either.
