A64

Allwinner A64 (sun50i) SoC features a Quad-Core Cortex-A53 ARM CPU, and a Mali400 MP2 GPU from ARM.

=Overview=

The A64 is basically an Allwinner H3 with the Cortex-A7 cores replaced with Cortex-A53 cores. They share most of the memory map, clocks, interrupts and also uses the same IP blocks. Differences between the H3 and the A64 seem to be:
 * The H3 has three USB host controllers, whereas the A64 has only one. Both SoCs have an additional USB-OTG controller, which is assumed to be used as normal host controller as well.
 * The H3 DRAM controller supports up to 2GB of RAM, the A64 supports up to 3 GB. Despite being a 64-bit chip, this makes the SoC entirely 32-bit on the physical side.
 * The H3 supports 5 UARTs, the A64 has 6 of them.
