[PATCH v3 00/17] Add Allwinner H3 SoC and Orange Pi PC Machine

[Niek Linnenbank]

Dear QEMU developers,

Hereby I would like to contribute the following set of patches to QEMU
which add support for the Allwinner H3 System on Chip and the
Orange Pi PC machine. The following features and devices are supported:

 * SMP (Quad Core Cortex A7)
 * Generic Interrupt Controller configuration
 * SRAM mappings
 * SDRAM controller
 * Real Time Clock
 * Timer device (re-used from Allwinner A10)
 * UART
 * SD/MMC storage controller
 * EMAC ethernet connectivity
 * USB 2.0 interfaces
 * Clock Control Unit
 * System Control module
 * Security Identifier device

Functionality related to graphical output such as HDMI, GPU,
Display Engine and audio are not included. Recently released
mainline Linux kernels (4.19 up to latest master), mainline U-Boot
and NetBSD 9.0-RC1 are known to work.

For full details on how to use the Orange Pi PC machine, see the file
docs/orangepi.rst which is included as a patch in this series.

The contents of this patch series is available on Github at:

  https://github.com/nieklinnenbank/qemu/tree/allwinner-h3-v3

The followings are currently known issues in this series:

  - NetBSD 9.0-RC1 reads out year 2050 from RTC, while Linux works fine
  - boot0 custom Allwinner bootloader not yet working
  - Watchdog not yet implemented, affects U-Boot 'reset' and shutdown/reboot
     -> This is part of the existing A10 timer that needs to be generalized 
first

Looking forward to your review comments. I will do my best
to update the patches where needed.
