273a70ae82 hw/arm/mps3r: Initial skeleton for mps3-an536 board
The AN536 is another FPGA image for the MPS3 development board. Unlike
the existing FPGA images we already model, this board uses a Cortex-R
family CPU, and it does not use any equivalent to the M-profile
"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.
It's therefore more convenient for us to model it as a completely
separate C file.

This commit adds the basic skeleton of the board model, and the
code to create all the RAM and ROM. We assume that we're probably
going to want to add more images in future, so use the same
base class/subclass setup that mps2-tz.c uses, even though at
the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

41581f1361 hw/arm: Add minimal support for the B-L475E-IOT01A board
This commit adds a new B-L475E-IOT01A board using the STM32L475VG SoC
as well as a dedicated documentation file.
The implementation is derived from the Netduino Plus 2 machine.
There are no peripherals implemented yet, only memory regions.

d9656f860a hw/ppc: Add emulation of AmigaOne XE board
The AmigaOne is a rebranded MAI Teron board that uses U-Boot firmware
with patches to support AmigaOS and is very similar to pegasos2 so can
be easily emulated sharing most code with pegasos2. The reason to
emulate it is that AmigaOS comes in different versions for AmigaOne
and PegasosII which only have drivers for one machine and firmware so
these only run on the specific machine. Adding this board allows
another AmigaOS version to be used reusing already existing peagasos2
emulation. (The AmigaOne was the first of these boards so likely most
widespread which then inspired Pegasos that was later replaced with
PegasosII due to problems with Articia S, so these have a lot of
similarity. Pegasos mainly ran MorphOS while the PegasosII version of
AmigaOS was added later and therefore less common than the AmigaOne
version.)

cc9ff56fc3 kconfig: Add PCIe devices to s390x machines
It is useful to extend the number of available PCIe devices to KVM guests
for passthrough scenarios and also to expose these models to a different
(big endian) architecture. Introduce a new config PCIE_DEVICES to select
models, Intel Ethernet adapters and one USB controller. These devices all
support MSI-X which is a requirement on s390x as legacy INTx are not
supported.

da324efb17 arm/Kconfig: Keep Kconfig default entries in default.mak as documentation
When we moved the arm default CONFIGs into Kconfig and removed them
from default.mak, we made it harder to identify which CONFIGs are
selected by default in case users want to disable them.

Bring back the default entries into default.mak, but keep them
commented out. This way users can keep their workflows of editing
default.mak to remove build options without needing to search through
Kconfig.

29d9efca16 arm/Kconfig: Do not build TCG-only boards on a KVM-only build
Move all the CONFIG_FOO=y from default.mak into "default y if TCG"
statements in Kconfig. That way they won't be selected when
CONFIG_TCG=n.

I'm leaving CONFIG_ARM_VIRT in default.mak because it allows us to
keep the two default.mak files not empty and keep aarch64-default.mak
including arm-default.mak. That way we don't surprise anyone that's
used to altering these files.

With this change we can start building with --disable-tcg.

99f2f2ad9e arm/Kconfig: Always select SEMIHOSTING when TCG is present
We are about to enable the build without TCG, so CONFIG_SEMIHOSTING
and CONFIG_ARM_COMPATIBLE_SEMIHOSTING cannot be unconditionally set in
default.mak anymore. So reflect the change in a Kconfig.

Instead of using semihosting/Kconfig, use a target-specific file, so
that the change doesn't affect other architectures which might
implement semihosting in a way compatible with KVM.

The selection from ARM_v7M needs to be removed to avoid a cycle during
parsing.

8afc43ea63 s390x/gdb: Split s390-virt.xml
Both TCG and KVM emulate ckc, cputm, last_break and prefix, and it's
quite useful to have them during debugging. Right now they are grouped
together with KVM-only pp, pfault_token, pfault_select and

TCG-emulated code.

Move KVM-only registers into the new s390-virt-kvm.xml file. Advertise
s390-virt.xml always, and the new s390-virt-kvm.xml only for KVM.

e995d5cce4 target/arm: Implement gdbstub pauth extension
The extension is primarily defined by the Linux kernel NT_ARM_PAC_MASK

The original gdb feature consists of two masks, data and code, which are
used to mask out the authentication code within a pointer.  Following
discussion with Luis Machado, add two more masks in order to support
pointers within the high half of the address space (i.e. TTBR1 vs TTBR0).

b5fcfe927b hw/openrisc: Add the OpenRISC virtual machine
This patch adds the OpenRISC virtual machine 'virt' for OpenRISC.  This
platform allows for a convenient CI platform for toolchain, software
ports and the OpenRISC linux kernel port.

Much of this has been sourced from the m68k and riscv virt platforms.

The platform provides:
 - OpenRISC SMP with up to 4 cpus
 - A virtio bus with up to 8 devices
 - Standard ns16550a serial
 - Goldfish RTC
 - SiFive TEST device for poweroff and reboot
 - Generated Device Tree to automatically configure the guest kernel

DINO refers to the GSC-PCI bridge device which will soon be handled separately,
however the QEMU HPPA machine is actually based upon the HPPA B160L as indicated
by the Linux kernel dmesg output when booted in qemu-system-hppa and the QEMU
MAINTAINERS file.

Update the machine configuration to use CONFIG_HPPA_B160L instead of CONFIG_DINO
and also update the machine description accordingly.

5852c1f865 hw/openrisc/openrisc_sim: Add automatic device tree generation
Using the device tree means that qemu can now directly tell
the kernel what hardware is configured rather than use having
to maintain and update a separate device tree file.

This patch adds automatic device tree generation support for the
OpenRISC simulator.  A device tree is built up based on the state of the
configure openrisc simulator.

This is then dumped to memory and the load address is passed to the
kernel in register r3.
