The various MPS2 boards implemented in mps2.c have multiple I2C
buses: a bus dedicated to the audio configuration, one for the LCD
touchscreen controller, and two which are connected to the external
Shield expansion connector. Mark the buses which are used only for
board-internal devices as 'full' so that if the user creates i2c
devices on the commandline without specifying a bus name then they
will be connected to the I2C controller used for the Shield
connector, where guest software will expect them.

The mps2-tz boards use a data-driven structure to create the devices
that sit behind peripheral protection controllers. Currently the
functions which create these devices are passed an 'opaque' pointer
which is always the address within the machine struct of the device
to create, and some "all devices need this" information like irqs and
addresses.
If a specific device needs more information than this, it is
currently not possible to pass that through from the PPCInfo
data structure. Add support for passing an extra data parameter,
so that we can more flexibly handle the needs of specific
device types. To provide some type-safety we make this extra
parameter a pointer to a union (which initially has no members).
In particular, we would like to be able to indicate which of the
i2c controllers are for on-board devices only and which are
connected to the external 'shield' expansion port; a subsequent
patch will use this mechanism for that purpose.

The stellaris-gptm timer currently uses system_clock_scale for one of
its timer modes where the timer runs at the CPU clock rate. Make it
use a Clock input instead.
We don't try to make the timer handle changes in the clock frequency
while the downcounter is running. This is not a change in behaviour
from the previous system_clock_scale implementation -- we will pick
up the new frequency only when the downcounter hits zero. Handling
dynamic clock changes when the counter is running would require state
that the current gptm implementation doesn't have.

If the user provides both a BIOS/firmware image and also a guest
kernel filename, arm_setup_firmware_boot() will pass the
kernel image to the firmware via the fw_cfg device. However we
weren't checking whether there really was a fw_cfg device present,
and if there wasn't we would crash.
This crash can be provoked with a command line such as
qemu-system-aarch64 -M raspi3 -kernel /dev/null -bios /dev/null -display none
It is currently only possible on the raspi3 machine, because unless
the machine sets info->firmware_loaded we won't call
arm_setup_firmware_boot(), and the only machines which set that are:
* virt (has a fw-cfg device)
* sbsa-ref (checks itself for kernel_filename && firmware_loaded)
* raspi3 (crashes)
But this is an unfortunate beartrap to leave for future machine
model implementors, so we should handle this situation in boot.c.
Check in arm_setup_firmware_boot() whether the fw-cfg device exists
before trying to load files into it, and if it doesn't exist then
exit with a hopefully helpful error message.
Because we now handle this check in a machine-agnostic way, we
can remove the check from sbsa-ref.

Commit bfae1772c4 ("hw/arm/fsl-imx25: Wire up eSDHC controllers")
added a dependency on the TYPE_IMX_USDHC model, but forgot to add
the Kconfig selector. Fix that to solve when built stand-alone:
$ qemu-system-arm -M imx25-pdk
qemu-system-arm: missing object type 'imx-usdhc'

The TYPE_NPCM7XX_SMBUS device model exposes an SMBus, but
this isn't advertised with proper Kconfig symbol, leading
to an early build failure when building NPCM7XX machines
standalone:
The following clauses were found for AT24C
config AT24C depends on I2C
select AT24C if NPCM7XX
Fix by adding SMBUS to NPCM7XX.

When we build IORT table with SMMUv3 and bypass iommu feature enabled,
we can no longer setup one map from RC to SMMUv3 covering the whole RIDs.
We need to walk the PCI bus and check whether the root bus will bypass
iommu, setup RC -> SMMUv3 -> ITS map for RC which will not bypass iommu.
When a SMMUv3 node exist, we setup the idmap from SMMUv3 to ITS
covering the whole RIDs, and only modify the map from RC to SMMUv3.
We build RC -> SMMUv3 -> ITS map for root bus with bypass_iommu
disabled, and build idmap from RC to ITS directly for the rest of
the whole RID space.
For example we run qemu with command line:
qemu/build/aarch64-softmmu/qemu-system-aarch64 \
-kernel arch/arm64/boot/Image \
-enable-kvm \
-cpu host \
-m 8G \
-smp 8,sockets=2,cores=4,threads=1 \
-machine virt,kernel_irqchip=on,gic-version=3,iommu=smmuv3,default_bus_bypass_iommu=true \
-drive file=./QEMU_EFI-pflash.raw,if=pflash,format=raw,unit=0,readonly=on \
-device pxb-pcie,bus_nr=0x10,id=pci.10,bus=pcie.0,addr=0x3.0x1 \
-device pxb-pcie,bus_nr=0x20,id=pci.20,bus=pcie.0,addr=0x3.0x2,bypass_iommu=true \
-device pcie-root-port,port=0x20,chassis=1,id=pci.1,bus=pcie.0,addr=0x2 \
-device pcie-root-port,port=0x20,chassis=11,id=pci.11,bus=pci.10,addr=0x1 \
-device pcie-root-port,port=0x20,chassis=21,id=pci.21,bus=pci.20,addr=0x1 \
-device virtio-scsi-pci,id=scsi0,bus=pci.1,addr=0x1 \
-device virtio-scsi-pci,id=scsi1,bus=pci.11,addr=0x1 \
-device virtio-scsi-pci,id=scsi2,bus=pci.21,addr=0x1 \
-initrd /mnt/davinci/wxg/kill-linux/rootfs/mfs.cpio.gz \
-nographic \
-append "rdinit=init console=ttyAMA0 earlycon=pl011,0x9000000 nokaslr" \
And we get guest configuration:
-+-[0000:20]---01.0-[21]--
+-[0000:10]---01.0-[11]--
\-[0000:00]-+-00.0 Device 1b36:0008
+-01.0 Device 1af4:1000
\-02.0-[01]--
With bypass_iommu enabled, the attached devices will bypass iommu.
