[Qemu-arm] [PATCH v4 0/5] ARM: Add NUMA support for machine virt

[Shannon Zhao]

From: Shannon Zhao <address@hidden>

Add NUMA support for machine virt. Tested successfully running a guest
Linux kernel with the following patch applied:

- [PATCH v9 0/6] arm64, numa: Add numa support for arm64 platforms
https://lwn.net/Articles/672329/
- [PATCH v2 0/4] ACPI based NUMA support for ARM64
http://www.spinics.net/lists/linux-acpi/msg61795.html

Changes since v3:
* based on new kernel driver and device bindings
* add ACPI part

Changes since v2:
* update to use NUMA node property arm,associativity.

Changes since v1:
Take into account Peter's comments:
* rename virt_memory_init to arm_generate_memory_dtb
* move arm_generate_memory_dtb to boot.c and make it a common func
* use a struct numa_map to generate numa dtb

Example qemu command line:
qemu-system-aarch64 \
    -enable-kvm -smp 4\
    -kernel Image \
    -m 512 -machine virt,kernel_irqchip=on \
    -initrd guestfs.cpio.gz \
    -cpu host -nographic \
    -numa node,mem=256M,cpus=0-1,nodeid=0 \
    -numa node,mem=256M,cpus=2-3,nodeid=1 \
    -append "console=ttyAMA0 root=/dev/ram"
