For powernv10-rainier, the Power Hypervisor code expects to see a
pca9554 device connected to the 3rd PNV I2C engine on port 1 at I2C
address 0x25 (or left-justified address of 0x4A). This is used by
the hypervisor code to detect if a "Cable Card" is present.

The QEMU I2C buses and devices use the resettable
interface for resetting while the PNV I2C controller
and parent buses and devices have not yet transitioned
to this new interface and use the old reset strategy.
This was preventing the I2C buses and devices wired
to the PNV I2C controller from being reset.
The short term fix for this is to have the PNV I2C
Controller's reset function explicitly call the resettable
interface function, bus_cold_reset(), on all child
I2C buses.
The long term fix should be to transition all PNV parent
devices and buses to use the resettable interface so that
all child buses and devices are automatically reset.

For power10-rainier, a pca9552 device is used for PCIe slot hotplug
power control by the Power Hypervisor code. The code expects that
some time after it enables power to a PCIe slot by asserting one of
the pca9552 GPIO pins 0-4, it should see a "power good" signal asserted
on one of pca9552 GPIO pins 5-9.
To simulate this behavior, we simply connect the GPIO outputs for
pins 0-4 to the GPIO inputs for pins 5-9.
Each PCIe slot is assigned 3 GPIO pins on the pca9552 device, for
control of up to 5 PCIe slots. The per-slot signal names are:
SLOTx_EN.......PHYP uses this as an output to enable
slot power. We connect this to the
SLOTx_PG pin to simulate a PGOOD signal.
SLOTx_PG.......PHYP uses this as in input to detect
PGOOD for the slot. For our purposes
we just connect this to the SLOTx_EN
output.
SLOTx_Control..PHYP uses this as an output to prevent
a race condition in the real hotplug
circuitry, but we can ignore this output
for simulation.

Allow external devices to drive pca9552 input pins by adding
input GPIO's to the model. This allows a device to connect
its output GPIO's to the pca9552 input GPIO's.
In order for an external device to set the state of a pca9552
pin, the pin must first be configured for high impedance (LED
is off). If the pca9552 pin is configured to drive the pin low
(LED is on), then external input will be ignored.
Here is a table describing the logical state of a pca9552 pin
given the state being driven by the pca9552 and an external device:
PCA9552
Configured
State
| Hi-Z | Low |
------+------+-----+
External Hi-Z | Hi | Low |
Device ------+------+-----+

The pca9552 INPUT0 and INPUT1 registers are supposed to
hold the logical values of the LED pins. A logical 0
should be seen in the INPUT0/1 registers for a pin when
its corresponding LSn bits are set to 0, which is also
the state needed for turning on an LED in a typical
usage scenario. Existing code was doing the opposite
and setting INPUT0/1 bit to a 1 when the LSn bit was
set to 0, so this commit fixes that.

cc1: all warnings being treated as errors
Looking at this code, the DO_UPCAST macro is indeed used in a wrong way
here: DO_UPCAST is supposed to check that the second parameter is the
first entry of the struct that the first parameter indicates, but since
we use and index into the info[] array, this of course cannot work.
The intention here was likely rather to use the container_of() macro
instead, so switch the code accordingly.

In the i386 PC machine, we want to run the pc_cmos_init_late()
function only once the IDE and floppy drive devices have been set up.
We currently do this using qemu_register_reset(), and then have the
function call qemu_unregister_reset() on itself, so it runs exactly
once.
This was an expedient way to do it back in 2010 when we first added
this (in commit c0897e0cb9), but now we have a more obvious point
to do "machine initialization that has to happen after generic device
init": the machine-init-done hook.
Do the pc_cmos_init_late() work from our existing PC machine init
done hook function, so we can drop the use of qemu_register_reset()
and qemu_unregister_reset().
Because the pointers to the devices we need (the IDE buses and the
RTC) are now all in the machine state, we don't need the
pc_cmos_init_late_arg struct and can just pass the PCMachineState
pointer.

Right now all subclasses of TYPE_ISA_SUPERIO have to specify an instance_size,
because the ISASuperIODevice struct adds fields to ISADevice but the type does
not include the increased instance size. Failure to do so results in an access
past the bounds of struct ISADevice as soon as isa_superio_realize is called.
Fix this by specifying the instance_size already in the superclass.

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.

The MPS2 SCC device is broadly the same for all FPGA images, but has
minor differences in the behaviour of the CFG registers depending on
the image. In many cases we don't really care about the functionality
controlled by these registers and a reads-as-written or similar
behaviour is sufficient for the moment.
For the AN536 the required behaviour is:
* A_CFG0 has CPU reset and halt bits
- implement as reads-as-written for the moment
* A_CFG1 has flash or ATCM address 0 remap handling
- QEMU doesn't model this; implement as reads-as-written
* A_CFG2 has QSPI select (like AN524)
- implemented (no behaviour, as with AN524)
* A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits"
- QEMU doesn't care about these, so use the existing
RAZ behaviour for convenience
* A_CFG4 is board rev (like all other images)
- no change needed
* A_CFG5 is ACLK frq in hz (like AN524)
- implemented as reads-as-written, as for other boards
* A_CFG6 is core 0 vector table base address
- implemented as reads-as-written for the moment
* A_CFG7 is core 1 vector table base address
- implemented as reads-as-written for the moment
Make the changes necessary for this; leave TODO comments where
appropriate to indicate where we might want to come back and
implement things like CPU reset.
The other aspects of the device specific to this FPGA image (like the
values of the board ID and similar registers) will be set via the
device's qdev properties.

Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a
non-secure EL2 virtual timer. We implemented the timer itself in the
CPU model, but never wired up its IRQ line to the GIC.
Wire up the IRQ line (this is always safe whether the CPU has the
interrupt or not, since it always creates the outbound IRQ line).
Report it to the guest via dtb and ACPI if the CPU has the feature.
The DTB binding is documented in the kernel's
Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml
and the ACPI table entries are documented in the ACPI specification
version 6.3 or later.
Because the IRQ line ACPI binding is new in 6.3, we need to bump the
FADT table rev to show that we might be using 6.3 features.
Note that exposing this IRQ in the DTB will trigger a bug in EDK2
versions prior to edk2-stable202311, for users who use the virt board
with 'virtualization=on' to enable EL2 emulation and are booting an
EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is
that EDK2 will assert on bootup:
ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48
If you see that assertion you should do one of:
* update your EDK2 binaries to edk2-stable202311 or newer
* use the 'virt-8.2' versioned machine type
* not use 'virtualization=on'
(The versions shipped with QEMU itself have the fix.)

The raven_io_ops MemoryRegionOps is the only one in the source tree
which sets .valid.unaligned to indicate that it should support
unaligned accesses and which does not also set .impl.unaligned to
indicate that its read and write functions can do the unaligned
handling themselves. This is a problem, because at the moment the
core memory system does not implement the support for handling
unaligned accesses by doing a series of aligned accesses and
combining them (system/memory.c:access_with_adjusted_size() has a
TODO comment noting this).
Fortunately raven_io_read() and raven_io_write() will correctly deal
with the case of being passed an unaligned address, so we can fix the
missing unaligned access support by setting .impl.unaligned in the
MemoryRegionOps struct.

The rutabaga resource associated with that resource_id is then leaked.

Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.
A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.
There are additional error codes and some of the 'questions' in
the comments are resolved now.
Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.
For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.

Found whilst testing a series for the linux kernel that actually
bothers to check if enabled is set. 0xB is the option used
for vast majority of DSDT entries in QEMU.
It is a little odd for a device that doesn't really exist and
is simply a hook to tell the OS there is a CEDT table but 0xB
seems a reasonable choice and avoids need to special case
this device in the OS.
Means:
* Device present.
* Device enabled and decoding it's resources.
* Not shown in UI
* Functioning properly
* No battery (on this device!)

In the current mdev_reg_read() implementation, it consistently returns
that the Media Status is Ready (01b). This was fine until commit
25a52959f9 ("hw/cxl: Add support for device sanitation") because the
media was presumed to be ready.
However, as per the CXL 3.0 spec "8.2.9.8.5.1 Sanitize (Opcode 4400h)",
during sanitation, the Media State should be set to Disabled (11b). The
mentioned commit correctly sets it to Disabled, but mdev_reg_read()
still returns Media Status as Ready.
To address this, update mdev_reg_read() to read register values instead
of returning dummy values.
Note that __toggle_media() managed to not only write something
that no one read, it did it to the wrong register storage and
so changed the reported mailbox size which was definitely not
the intent. That gets fixed as a side effect of allocating
separate state storage for this register.

The addition of the DCD support for CXL type-3 devices extended the CDAT
table large enough that the checksum being returned was incorrect.[1]
This was because the checksum value was using the header length field
rather than each of the 4 bytes of the length field. This was
previously not seen because the length of the CDAT data was less than
256 thus resulting in an equivalent checksum value.
Properly calculate the checksum for the CDAT header.

The VIA south bridges are able to relocate and toggle (enable or disable) their
SuperI/O functions. So far this is hardcoded such that all functions are always
enabled and are located at fixed addresses.
Some PC BIOSes seem to probe for I/O occupancy before activating such a function
and issue an error in case of a conflict. Since the functions are currently
enabled on reset, conflicts are always detected. Prevent that by implementing
relocation and toggling of the SuperI/O functions.
Note that all SuperI/O functions are now deactivated upon reset (except for
VT82C686B's serial ports where Fuloong 2e's rescue-yl seems to expect them to be

QEMU populates the apic_state attribute of x86 CPUs if supported by real
hardware or if SMP is active. When handling interrupts, it just checks whether
apic_state is populated to route the interrupt to the PIC or to the APIC.
However, chapter 10.4.3 of [1] requires that:
When IA32_APIC_BASE[11] is 0, the processor is functionally equivalent to an
IA-32 processor without an on-chip APIC.
This means that when apic_state is populated, QEMU needs to check for the
MSR_IA32_APICBASE_ENABLE flag in addition. Implement this which fixes some
real-world BIOSes.

This commit adds XTSup configuration to let user choose to whether enable

Additionally, this commit exports IVHD type 0x11 besides the old IVHD type
0x10 in ACPI table. IVHD type 0x10 does not report full set of IOMMU
features only the legacy ones, so operating system (e.g. Linux) may only
detects x2APIC support if IVHD type 0x11 is available. The IVHD type 0x10
is kept so that old operating system that only parses type 0x10 can detect
the IOMMU device.
Besides, an amd_iommu-stub.c file is created to provide the definition for
amdvi_extended_feature_register when CONFIG_AMD_IOMMU=n. This function is
used by acpi-build.c to get the extended feature register value for
building the ACPI table. When CONFIG_AMD_IOMMU=y, this function is defined
in amd_iommu.c.

Currently the DRQ IRQ is updated every time DMA data is sent/received which
is both inefficient and causes excessive logging of the DRQ state. Add a
new drq_state bool that only updates the DRQ IRQ if its state changes.
This commit adds the new drq_state bool to the migration state: since the
version number has already been increased earlier in the series, there is
no need to repeat it again here. The DRQ IRQ is (currently) only used for
PDMA transfers which already have a migration break in this series so
there are no problems setting its value post-load.

The latest state machines can handle mixing DMA and non-DMA FIFO access for all
SCSI phases except DATA IN and DATA OUT. For DATA IN and DATA OUT phases, the
transfer is complete when TC == 0 and the updated logic will now handle TC
underflow correctly, which makes it just about impossible to manually manipulate
the FIFO during a DMA transfer.
Remove the restriction on FIFO read access when DMA memory routines are defined
which also allows the NeXTCube machine to pass its self-test.

Detect the case where the guest underflows TC by requesting a DMA transfer which
is larger than the available data. If this case is detected, immediately
complete the SCSI request and handle any remaining FIFO accesses in the STATUS
phase by raising INTR_BS once the FIFO is below the threshold.
Note that handling the premature SCSI bus phase change in the case of TC
underflow fixes booting EMILE on m68k once again.

Both esp_raise_irq() and esp_lower_irq() check the STAT_INT bit in ESP_RSTAT
to ensure that the IRQ is raised or lowered if its state changes. When reading
ESP_RINTR, esp_lower_irq() was being called *after* ESP_RSTAT had been
cleared meaning that STAT_INT was already clear, and so if STAT_INT was
asserted beforehand then the esp_lower_irq() would have no effect.

Currently any write to the ESP FIFO in the MESSAGE OUT or COMMAND phases will
manually raise the bus service interrupt. Instead of duplicating the interrupt
logic in esp_reg_write(), update esp_do_nodma() to correctly process incoming
FIFO data during the MESSAGE OUT and COMMAND phases. Part of this change is to
call esp_nodma_ti_dataout() from handle_ti() to ensure that the DATA OUT phase
FIFO transfer only occurs when executing a non-DMA TI command instead of for
each byte entering the FIFO.
One slight complication is that NextSTEP uses multiple TI commands to transfer
the CDB one byte at a time (as opposed to loading the FIFO and using a single
TI command), so it is necessary to determine the expected length of the SCSI
CDB being received. This is handled by the introduction of a new
esp_cdb_length() function which returns the expected SCSI CDB length based
upon the first command byte.

In the case where a SCSI command with a DATA IN phase has been issued, the host
may preload the FIFO with unaligned bytes before issuing the main DMA transfer.
When accumulating data in the FIFO don't raise the INTR_BS interrupt until the
TI command is issued, otherwise the unexpected interrupt can confuse the host.
In particular this is needed to prevent the MacOS Disk Utility from failing
when switching non-DMA transfers to use esp_do_nodma().
