[Qemu-arm] [PATCH v4 0/8] Raspberry Pi 2 support

From: Andrew Baumann
Subject: [Qemu-arm] [PATCH v4 0/8] Raspberry Pi 2 support
Date: Fri, 15 Jan 2016 15:58:49 -0800

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

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 
 * changed how I allocate and pass ram from the board through to the SoC
 * cleanup raspi_platform.h
 * s/_/-/ in device/property/type names

v4 changes:
 * refactoring in bcm2836_control
 * minor cleanup / style tweaks in other device emulations
 * use qemu MAC address in bcm2835_property
 * avoid use of smp_cpus outside raspi.c
 * made setup blobs relocatable, and merged with highbank's copy in common code

XXX: patch 7/8 (new in v4) changes the secure boot setup blob for
Highbank to a common version shared with pi, and I have not tested it
with that board.


Andrew Baumann (8):
  bcm2835_mbox: add BCM2835 mailboxes
  bcm2835_property: add bcm2835 property channel
  bcm2835_ic: add bcm2835 interrupt controller
  bcm2835_peripherals: add rollup device for bcm2835 peripherals
  bcm2836_control: add bcm2836 ARM control logic
  bcm2836: add bcm2836 soc device
  arm/boot: move highbank secure board setup code to common routine
  raspi: add raspberry pi 2 machine
