V40

Allwinner V40 (sun8i) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. It is the automotive version of R40.

=Overview= There is no support for the V40 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 for R40 that should be compatible with V40.
