H6

Allwinner H6 (sun50iw6p1) SoC features a Quad-Core Cortex-A53 ARM CPU, and a Mali-T720 MP2 GPU from ARM. The Allwinner H6 is an OTT SoC.

=Overview= Mainline support not started yet due to lack of boards. Xunlong and Pine64 are working on H6 SBCs.

High level differences

 * addition of PCIe support
 * single lane PCIe 2.0
 * totally undocumented software interface
 * addition of USB 3.0 host
 * Mali T720 instead of Mali 450
 * DDR4 DRAM support
 * addition of IOMMU
 * though only connected to display controller and video codecs
 * (New?) Audio Hub component

programming model/driver level differences

 * heavily changed memory map (UART0 at 0x05000000, for instance)
 * SRAM locations moved around as well (SRAM A1 at 0x2000 now)
 * bus clock gates and device reset control now grouped by devices and merged into one register (high 16 bits reset, low 16 bits clock gates)
 * DMA controller changed (more than 32 ports, but still limited to 32 bit addresses)
 * no GPIO port A and B
