[Qemu-devel] [PATCH v3 0/7] Raspberry Pi 2 support

[Andrew Baumann <Andrew.Baumann@microsoft.com>]

This patch series adds initial support for Raspberry Pi 2
(bcm2836). It is heavily based on the original (out of tree) work of
Gregory Estrade, Stefan Weil and others to support Raspberry Pi
1. Thanks are also due to Peter Crosthwaite for the code reviews and
feedback.

At the end of this series, it is possible to boot a recent raspbian
kernel to a serial console using an invocation such as:

  qemu-system-arm -M raspi2 -kernel raspbian-boot/kernel7.img -sd
  2015-09-24-raspbian-jessie.vhd -append "rw earlyprintk loglevel=8
  console=ttyAMA0 root=/dev/mmcblk0p2" -serial stdio

(where raspbian-boot is the boot partition from the matching image,
and after commenting-out or removing /etc/ld.so.preload to avoid an
unimplemented setend instruction).

I plan to add DMA, USB, framebuffer, timers, and other system devices
(power, mphi, aux/uart1) in future patches. In the meantime, the
complete code is available at: https://github.com/0xabu/qemu

Although this series includes many of the peripherals common to Pi1
(aka bcm2835 aka Pi0), it's not yet possible to boot a Pi1, because it
requires additional peripherals, so I'll also add that SoC and machine
in a later patch.

v2 changes:
 * cleanup based on reviews of mbox and ic devices by Peter Crosthwaite
   (see specific notes on each patch)
 * removed custom SD controller in favour of sdhci

v3 changes:
 * cleanup/tweaks to mbox, ic, peripherals and bcm2836_control devices from v2 review
 * changed how I allocate and pass ram from the board through to the SoC
 * cleanup raspi_platform.h
 * s/_/-/ in device/property/type names

Cheers,
Andrew
