drive_get_next() is basically a bad idea. It returns the "next" block
backend of a certain interface type. "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.
This lets you define unit numbers implicitly by execution order. If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break. Hard to spot in review.
Machine "quanta-gbs-bmc" connects just one backend with
drive_get_next(), but with a helper function. Change it to use
drive_get() directly. This makes the unit numbers explicit in the
code.

ssi_sd_realize() creates an "sd-card" device. This is inappropriate,
and marked FIXME.
Move it to the boards that create these devices. Prior art: commit
eb4f566bbb for device "generic-sdhci", and commit 26c607b86b for
device "pl181".
The device remains not user-creatable, because its users should (and
do) wire up its GPIO chip-select line.

The virt machine has properties to enable MTE and Nested Virtualization
support. However, its check to ensure the backing accel implementation
supports it today only looks for KVM and bails out if it finds it.
Extend the checks to HVF as well as it does not support either today.
This will cause QEMU to print a useful error message rather than
silently ignoring the attempt by the user to enable either MTE or
the Virtualization extensions.

Since commit d8fb7d0969 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.
This affects option default_bus_bypass_iommu which was introduced in the
same release:
$ qemu-system-aarch64 -M virt,default_bus_bypass_iommu=on
qemu-system-aarch64: Property 'virt-6.1-machine.default-bus-bypass-iommu' not found
Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.

Support device tree CPU topology descriptions.
In accordance with the Devicetree Specification, the Linux Doc
"arm/cpus.yaml" requires that cpus and cpu nodes in the DT are
present. And we have already met the requirement by generating
/cpus/cpu@* nodes for members within ms->smp.cpus. Accordingly,
we should also create subnodes in cpu-map for the present cpus,
each of which relates to an unique cpu node.
The Linux Doc "cpu/cpu-topology.txt" states that the hierarchy
of CPUs in a SMP system is defined through four entities and
they are socket/cluster/core/thread. It is also required that
a socket node's child nodes must be one or more cluster nodes.
Given that currently we are only provided with information of
socket/core/thread, we assume there is one cluster child node
in each socket node when creating cpu-map.

On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.
Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

As specified by linux device-tree binding document, the device-tree
nodes for these empty NUMA nodes shouldn't be generated. However,
the corresponding NUMA node IDs should be included in the distance
map. The memory hotplug through device-tree on ARM64 isn't existing
so far and it's not necessary to require the user to provide a distance
map. Furthermore, the default distance map Linux generates may even be
sufficient. So this simply skips populating the device-tree nodes for
these empty NUMA nodes to avoid the error, so that QEMU can be started
successfully.

In the real SMP hardware topology world, it's much more likely that
we have high cores-per-socket counts and few sockets totally. While
the current preference of sockets over cores in smp parsing results
in a virtual cpu topology with low cores-per-sockets counts and a
large number of sockets, which is just contrary to the real world.
Given that it is better to make the virtual cpu topology be more
reflective of the real world and also for the sake of compatibility,
we start to prefer cores over sockets over threads in smp parsing
since machine type 6.2 for different arches.
In this patch, a boolean "smp_prefer_sockets" is added, and we only
enable the old preference on older machines and enable the new one
since type 6.2 for all arches by using the machine compat mechanism.

The Linux spi-imx driver does not work on QEMU. The reason is that the
state of m25p80 loops in STATE_READING_DATA state after receiving
RDSR command, the new command is ignored. Before sending a new command,
CS line should be pulled high to make the state of m25p80 back to IDLE.
Currently the SPI flash CS line is connected to the SPI controller, but
on the real board, it's connected to GPIO3_19. This matches the ecspi1
device node in the board dts.
ecspi1 node in imx6qdl-sabrelite.dtsi:
&ecspi1 {
cs-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi1>;
status = "okay";
flash: m25p80@0 {
compatible = "sst,sst25vf016b", "jedec,spi-nor";
spi-max-frequency = <20000000>;
reg = <0>;
};
};
Should connect the SSI_GPIO_CS to GPIO3_19 when adding a spi-nor to
spi1 on sabrelite machine.

Connect the support for ZynqMP eFUSE one-time field-programmable
bit array.
The command argument:
-drive if=pflash,index=3,...
Can be used to optionally connect the bit array to a
backend storage, such that field-programmed values
in one invocation can be made available to next
invocation.
The backend storage must be a seekable binary file, and
its size must be 768 bytes or larger. A file with all
binary 0's is a 'blank'.

The Allwinner H3 SoC uses Cortex-A7 cores which support virtualization.
However, today we are configuring QEMU to use HVC as PSCI conduit.
That means HVC calls get trapped into QEMU instead of the guest's own
emulated CPU and thus break the guest's ability to execute virtualization.
Fix this by moving to SMC as conduit, freeing up HYP completely to the VM.

When you run QEMU with an Aspeed machine and a single serial device
using stdio like this:
qemu -machine ast2600-evb -drive ... -serial stdio
The guest OS can read and write to the UART5 registers at 0x1E784000 and
it will receive from stdin and write to stdout. The Aspeed SoC's have a
lot more UART's though (AST2500 has 5, AST2600 has 13) and depending on
the board design, may be using any of them as the serial console. (See
"stdout-path" in a DTS to check which one is chosen).
Most boards, including all of those currently defined in
hw/arm/aspeed.c, just use UART5, but some use UART1. This change adds
some flexibility for different boards without requiring users to change
their command-line invocation of QEMU.
I tested this doesn't break existing code by booting an AST2500 OpenBMC
image and an AST2600 OpenBMC image, each using UART5 as the console.
Then I tested switching the default to UART1 and booting an AST2600
OpenBMC image that uses UART1, and that worked too.

This is the latest revision of the ASPEED 2600 SoC. As there is no
need to model multiple revisions of the same SoC for the moment,
update the SCU AST2600 to model the A3 revision instead of the A1 and
adapt the AST2600 SoC and machines.
Reset values are taken from v8 of the datasheet.

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.
