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= See Mainlining Effort and Mainline U-Boot for support status. The initial support for the SoC will be added in kernel 4.17

High level differences

 * addition of PCIe support (broken, see below)
 * 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

Errata
Allwinner H6 has a quirky PCIe controller that doesn't map the PCIe address space properly (only 64k accessible at one time) to CPU, and accessing the PCIe config space, I/O space or memory space will need to be wrapped. As Linux doesn't wrap PCIe memory space access, it's not possible to do a proper PCIe controller driver for H6. The BSP kernel modifies the driver to wrap the access, so it's also not generic, and only devices with modified driver will work. Some Allwinner H6 not all has a quirky Watchdog that doesn't make the SoC reboot.
 * The PCIe implementation is broken.
 * The Watchdog implementation is broken.
