A33

Allwinner A33 (sun8i) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. It is a Quad-Core pin-to-pin-compatible version of A23 (which in turn is a lower power, cut-down, not-pin-compatible version of the A20).

=Overview= There is no support for the A33 in the linux-sunxi 3.4 kernel and in u-boot-sunxi. Support in mainline u-boot and in the mainline kernel is work in progress.
