This introduces a really basic PECI controller that responses to
commands by always setting the response code to success and then raising
an interrupt to indicate the command is done. This helps avoid getting
hit with constant errors if the driver continuously attempts to send a
command and keeps timing out.
The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC.
They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support
PECI 4.0, which includes more read/write buffer registers from 0x80 to
0xFC to support 64-byte mode.
This patch doesn't attempt to handle that, or to create a different
version of the controller for the different generations, since it's only
implementing functionality that is common to all generations.
The basic sequence of events is that the firmware will read and write to
various registers and then trigger a command by setting the FIRE bit in
the command register (similar to the I2C controller).
Then the firmware waits for an interrupt from the PECI controller,
expecting the interrupt status register to be filled in with info on
what happened. If the command was transmitted and received successfully,
then response codes from the host CPU will be found in the data buffer
registers.

The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.
To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus
and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as
confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

The VIA2 on the Q800 machine is not a separate chip as in older Macs but instead
is integrated into the on-board logic. From analysing the SCSI routines in the
MacOS toolbox ROM (and to a lesser extent NetBSD and Linux) the expectation seems
to be that the SCSI_DATA (DRQ) bit is live on the Q800 and not latched.
Fortunately we can use the recently introduced mos6522 last_irq_levels variable
which tracks the edge-triggered state to return the SCSI_DATA (DRQ) bit live to
the guest OS.

The migration code will not look at a VMStateDescription's
minimum_version_id_old field unless that VMSD has set the
load_state_old field to something non-NULL. (The purpose of
minimum_version_id_old is to specify what migration version is needed
for the code in the function pointed to by load_state_old to be able
to handle it on incoming migration.)
We have exactly one VMSD which still has a load_state_old,
in the PPC CPU; every other VMSD which sets minimum_version_id_old
is doing so unnecessarily. Delete all the unnecessary ones.
Commit created with:
sed -i '/\.minimum_version_id_old/d' $(git grep -l '\.minimum_version_id_old')
with the one legitimate use then hand-edited back in.

softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff(). Currently we keep the prototypes for these in
qemu-common.h, but most files don't need them. Move them to their
own header, a new include/sysemu/rtc.h.
Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.
The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

Aspeed 2600 SDK enables I3C support by default. The I3C driver will try
to reset the device controller and set it up through device address table
register. This dummy model responds to these registers with default values
as listed in the ast2600v10 datasheet chapter 54.2.
This avoids a guest machine kernel panic due to referencing an
invalid kernel address if the device address table register isn't
set correctly.

The ivshmem device, as with most PCI devices, uses little endian byte
order. However, the endianness of its mmio_ops is marked as
DEVICE_NATIVE_ENDIAN. This presents not only the usual problems with big
endian hosts but also with PowerPC little endian hosts as well, since
the Power architecture in QEMU uses big endian hardware (XIVE controller,
PCI Host Bridges, etc) even if the host is in little endian byte order.
As it is today, the IVPosition of the device will be byte swapped when
running in Power BE and LE. This can be seen by changing the existing
qtest 'ivshmem-test' to run in ppc64 hosts and printing the IVPOSITION
regs in test_ivshmem_server() right after the VM ids assert. For x86_64
the VM id values read are '0' and '1', for ppc64 (tested in a Power8
RHEL 7.9 BE server) and ppc64le (tested in a Power9 RHEL 8.6 LE server)
the ids will be '0' and '0x1000000'.
Change this device to LITTLE_ENDIAN fixes the issue for Power hosts of
both endianness, and every other big-endian architecture that might use
this device, without impacting x86 users.

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.
A number of machines connect just one backend with drive_get_next().
Change them to use drive_get() directly. This makes the (zero) unit
number explicit in the code.

Configuring a drive with "if=none" is meant for creation of a backend
only, it should not get automatically assigned to a device frontend.
Use "if=pflash" for the One-Time-Programmable device instead (like
it is e.g. also done for the efuse device in hw/arm/xlnx-zcu102.c).
Since the old way of configuring the device has already been published
with the previous QEMU versions, we cannot remove this immediately, but
have to deprecate it and support it for at least two more releases.

UART5 is typically used as the default debug UART on the AST2600, but
UART1 is also designed to be a debug UART. All the AST2600 UART's have
semi-configurable clock rates through registers in the System Control
Unit (SCU), but only UART5 works out of the box with zero-initialized
values. The rest of the UART's expect a few of the registers to be
initialized to non-zero values, or else the clock rate calculation will
yield zero or undefined (due to a divide-by-zero).
For reference, the U-Boot clock rate driver here shows the calculation:
https://github.com/facebook/openbmc-uboot/blob/15f7e0dc01d8/drivers/clk/aspeed/clk_ast2600.c#L357
To summarize, UART5 allows selection from 4 rates: 24 MHz, 192 MHz, 24 /
13 MHz, and 192 / 13 MHz. The other UART's allow selecting either the
"low" rate (UARTCLK) or the "high" rate (HUARTCLK). UARTCLK and HUARTCLK
are configurable themselves:
UARTCLK = UXCLK * R / (N * 2)
HUARTCLK = HUXCLK * HR / (HN * 2)
UXCLK and HUXCLK are also configurable, and depend on the APLL and/or
HPLL clock rates, which also derive from complicated calculations. Long
story short, there's lots of multiplication and division from
configurable registers, and most of these registers are zero-initialized
in QEMU, which at best is unexpected and at worst causes this clock rate
driver to hang from divide-by-zero's. This can also be difficult to
diagnose, because it may cause U-Boot to hang before serial console
initialization completes, requiring intervention from gdb.
This change just initializes all of these registers with default values
from the datasheet.
To test this, I used Facebook's AST2600 OpenBMC image for "fuji", with
the following diff applied (because fuji uses UART1 for console output,
not UART5).
@@ -323,8 +323,8 @@ static void aspeed_soc_ast2600_realize(DeviceState *dev, Error **errp)

/* UART - attach an 8250 to the IO space as our UART5 */

+ aspeed_soc_get_irq(s, ASPEED_DEV_UART1),
38400, serial_hd(0), DEVICE_LITTLE_ENDIAN);
/* I2C */
Without these clock rate registers being initialized, U-Boot hangs in
the clock rate driver from a divide-by-zero, because the UART1 clock
rate register reads return zero, and there's no console output. After
initializing them with default values, fuji boots successfully.

As of today, when booting upstream U-Boot for Xilinx Zynq, the UART
does not receive anything. Debugging shows that the UART input clock
frequency is zero which prevents the UART from receiving anything as
per the logic in uart_receive().
From zynq_slcr_reset_exit() comment, it intends to compute output
clocks according to ps_clk and registers. zynq_slcr_compute_clocks()
is called to accomplish the task, inside which device_is_in_reset()
is called to actually make the attempt in vain.
Rework reset_hold() and reset_exit() so that in the reset exit phase,
the logic can really compute output clocks in reset_exit().
With this change, upstream U-Boot boots properly again with:
$ qemu-system-arm -M xilinx-zynq-a9 -m 1G -display none -serial null -serial stdio \
-device loader,file=u-boot-dtb.bin,addr=0x4000000,cpu-num=0

The original implementation of the Macintosh VIA devices in commit 6dca62a000
"hw/m68k: add VIA support" used timer optimisations to reduce high CPU usage on
the host when booting Linux. These optimisations worked by waiting until VIA1
port B was accessed before re-arming the timers.
The MacOS toolbox ROM constantly writes to VIA1 port B which calls
via1_one_second_update() and via1_sixty_hz_update() to calculate the new expiry
time, causing the timers to constantly reset and never fire. The effect of this
is that the Ticks (0x16a) global variable holding the number of 60Hz timer ticks
since reset is never incremented by the interrupt causing time to stand still.
Whilst the code was introduced as a performance optimisation, it is likely that
the high CPU usage was actually caused by the incorrect 60Hz timer interval
fixed in the previous patch. Remove the optimisation to keep everything simple
and enable the MacOS toolbox ROM to start keeping time.

The 60Hz timer is initialised using timer_new_ns() meaning that the timer
interval should be measured in ns, and therefore its period is a thousand
times too short.
Use a define for the 60Hz timer period taking the more precise value as
documented in the Guide To The Macintosh Family Hardware.

According to the "Guide To The Macintosh Family Hardware", the 60Hz VIA1 timer
on newer Macs such as the Quadra only exists for compatibility with old software
and is no longer synced to the VBL interval.
Rename the VBL timer to 60Hz timer to emphasise this and to prevent confusion

The current workaround for the Linux ADB state machine in kernels < 5.6 switching
the VIA back to IDLE state between send and receive modes is to re-inject the
first byte of the response in the IDLE state, and then force the state machine
into generating an autopoll reply.
In fact what is happening is much simpler: analysis of traces from a real Quadra
suggest that the existing data is returned as the first autopoll response rather
than generating an immediate response starting whilst still in IDLE state.
Update the ADB receive code to work in the same way, which allows the re-injection
code to be completely removed from adb_via_receive() and for adb_via_poll() to
be simplified accordingly.

This patch implements Multi Function Timer (MFT) module for NPCM7XX.
This module is mainly used to configure PWM fans. It has just enough
functionality to make the PWM fan kernel module work.
The module takes two input, the max_rpm of a fan (modifiable via QMP)
and duty cycle (a GPIO from the PWM module.) The actual measured RPM
is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is
measured as a counter compared to a prescaled input clock. The kernel
driver reads this counter and report to user space.

IO cycles from the BMC to the host.
Expose support on the BMC side by implementing the usual MMIO

The model caters to the IRQ style of both the AST2600 and the earlier
SoCs (AST2400 and AST2500). The AST2600 allocates an IRQ for each LPC
sub-device, while there is a single IRQ shared across all subdevices on

The sysctl PDCM_PD_*_SENSE registers control various power domains in
the system and allow the guest to configure which conditions keep a
power domain awake and what power state to use when the domain is in
a low power state. QEMU doesn't model power domains, so for us these

some registers have moved address or have different behaviours.
In this commit we add case statements for the registers where
the SSE-300 and SSE-200 have the same behaviour. Some registers

0xc SCSECCTRL
0x10 CLK_CFG0 -- this is like SSE-200 FCLK_DIV but with a

0x14 CLK_CFG1 -- similar to SSE-200 SYSCLK_DIV; our implementation

0x100 RESET_SYNDROME -- bit allocation differs from SSE-200 but our

0x108 SWRESET
0x10c GRETREG

Remove the is_sse200 flag in favour of just directly testing the new

Since some of these registers exist in the SSE-300 but some do not or
have different behaviour, we expand out the if() statements in the
read and write functions into switch()es, so we have an easy place to
put SSE-300 specific behaviour.
(Until we do add the SSE-300 behaviour, the thing preventing us

We model Arm "Subsystems for Embedded" SoC subsystems using generic
code which is split into various sub-devices which are configurable
by QOM properties to handle the behaviour differences between the SSE
subsystems we implement. Currently the only sub-device which needs
to change is the IOTKIT_SYSCTL device, and we do this with a mix of
properties that directly specify divergent behaviours (eg
CPUWAIT_RST) and passing it the SYS_VERSION register value as a way
for it to distinguish IoTKit from SSE-200.
The "pass SYS_VERSION" approach is already a bit hacky, since the
IOTKIT_SYSCTL device has to know that the different part of the
register value happens to be bits [31:28]. For SSE-300 this register
is renamed SOC_IDENTITY and has a different format entirely, all of
whose fields can be configured by the SoC integrator when they
integrate the SSE into their SoC, and so "pass SYS_VERSION" breaks
down completely.
Switch to using a simple integer property representing an
internal-to-QEMU enumeration of the SSE flavour. For the moment we
only need this in IOTKIT_SYSCTL, but as we add SSE-300 support a few
of the other devices will also need to know.
We define and permit a value for the SSE-300 so we can start using
it in subsequent commits which add SSE-300 support.
The now-redundant is_sse200 flag in IoTKitSysCtl will be removed
in the following commit.

The Clock framework allows users to specify a callback which is
called after the clock's period has been updated. Some users need to
also have a callback which is called before the clock period is
updated.
As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.
Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

Update old infocenter.arm.com URLs to the equivalent developer.arm.com
ones (the old URLs should redirect, but we might as well avoid the
redirection notice, and the new URLs are pleasantly shorter).
This commit covers the links to the MPS2 board TRM, the various
Application Notes, the IoTKit and SSE-200 documents.

The AN524 version of the SCC interface has different behaviour for
some of the CFG registers; implement it.
Each board in this family can have minor differences in the meaning
of the CFG registers, so rather than trying to specify all the
possible semantics via individual device properties, we make the
behaviour conditional on the part-number field of the SCC_ID register
which the board code already passes us.
For the AN524, the differences are:
* CFG3 is reserved rather than being board switches
* CFG5 is a new register ("ACLK Frequency in Hz")
* CFG6 is a new register ("Clock divider for BRAM")
We implement both of the new registers as reads-as-written.

MPS3 boards have an extra SWITCH register in the FPGAIO block which
reports the value of some switches. Implement this, governed by a
property the board code can use to specify whether whether it exists.

The MPS2 board has 2 LEDs, but the MPS3 board has 10 LEDs. The
FPGAIO device is similar on both sets of boards, but the LED0
register has correspondingly more bits that have an effect. Add a
device property for number of LEDs.

Currently the MPS2 SCC device implements a fixed number of OSCCLK
values (3). The variant of this device in the MPS3 AN524 board has 6
OSCCLK values. Switch to using a PROP_ARRAY, which allows board code
to specify how large the OSCCLK array should be as well as its
values.
With a variable-length property array, the SCC no longer specifies
default values for the OSCCLKs, so we must set them explicitly in the
board code. This defaults are actually incorrect for the an521 and
an505; we will correct this bug in a following patch.
This is a migration compatibility break for all the mps boards.

Update infocenter.arm.com URLs for various pieces of Arm
documentation to the new developer.arm.com equivalents. (There is a
redirection in place from the old URLs, but we might as well update
our comments in case the redirect ever disappears in future.)
This patch covers all the URLs which are not MPS2/SSE-200/IoTKit
related (those are dealt with in a different patch).
