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
when the real VBL interrupt (now handled as a NuBus slot interrupt) is added in
future.

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.

This patch adds GPIOs in NPCM7xx PWM module for its duty values.
The purpose of this is to connect it to the MFT module to provide
an input for measuring a PWM fan's RPM. Each PWM module has
NPCM7XX_PWM_PER_MODULE of GPIOs, each one corresponds to
one PWM instance and can connect to multiple fan instances in MFT.

Keyboard-Controller-Style devices for IPMI purposes are exposed via LPC
IO cycles from the BMC to the host.
Expose support on the BMC side by implementing the usual MMIO
behaviours, and expose the ability to inspect the KCS registers in
"host" style by accessing QOM properties associated with each register.
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 AST2400 and AST2500.

For the AN547 image, the FPGAIO block has an extra DBGCTRL register,
which is used to control the SPNIDEN, SPIDEN, NPIDEN and DBGEN inputs
to the CPU. These signals control when the CPU permits use of the
external debug interface. Our CPU models don't implement the
external debug interface, so we model the register as
reads-as-written.
Implement the register, with a property defining whether it is
present, and allow mps2-tz boards to specify that it is present.

The SSE-300 has a new register block CPU<N>_PWRCTRL. There is one
instance of this per CPU in the system (so just one for the SSE-300),
and as well as the usual CIDR/PIDR ID registers it has just one
register, CPUPWRCFG. This register allows the guest to configure
behaviour of the system in power-down and deep-sleep states. Since
QEMU does not model those, we make the register a dummy
reads-as-written implementation.

The SSE-200 and SSE-300 have different PID register values from the
IoTKit for the sysctl register block. We incorrectly implemented the
SSE-200 with the same PID values as IoTKit. Fix the SSE-200 bug and
report these register values for SSE-300.

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
registers are dummy reads-as-written implementations.
The SSE-300 has a different power domain setup, so the set of
registers is slightly different:
Offset SSE-200 SSE-300
---------------------------------------------------
0x200 PDCM_PD_SYS_SENSE PDCM_PD_SYS_SENSE
0x204 reserved PDCM_PD_CPU0_SENSE
0x208 reserved reserved
0x20c PDCM_PD_SRAM0_SENSE reserved
0x210 PDCM_PD_SRAM1_SENSE reserved
0x214 PDCM_PD_SRAM2_SENSE PDCM_PD_VMR0_SENSE
0x218 PDCM_PD_SRAM3_SENSE PDCM_PD_VMR1_SENSE
Offsets 0x200 and 0x208 are the same for both, so handled in a
previous commit; here we deal with 0x204, 0x20c, 0x210, 0x214, 0x218.
(We can safely add new lines to the SSE300 vmstate because no board
uses this device in an SSE300 yet.)

The SSE-300 has a new PWRCTRL register at offset 0x1fc (previously
reserved). This register controls accessibility of some registers
in the Power Policy Units (PPUs). Since QEMU doesn't implement
the PPUs, we don't need to implement any real behaviour for this
register, so we just handle the UNLOCK bit which controls whether
writes to the register itself are permitted and otherwise make it
be reads-as-written.

The SSE-300 has only one CPU and so no INITSVTOR1. It does
have INITSVTOR0, but unlike the SSE-200 this register now
has a LOCK bit which can be set to 1 to prevent any further
writes to the register. Implement these differences.

In the SSE-300 the CPU_WAIT and NMI_ENABLE registers have
moved offsets, so they are now where the SSE-200's WICCTRL
and EWCTRL were. The SSE-300 does not have WICCTLR or EWCTRL
at all, and the old offsets are reserved:
Offset SSE-200 SSE-300
-----------------------------------
0x118 CPUWAIT reserved
0x118 NMI_ENABLE reserved
0x120 WICCTRL CPUWAIT
0x124 EWCTRL NMI_ENABLE
Handle this reshuffle, and the fact that SSE-300 has only
one CPU and so only one active bit in CPUWAIT.

The SSE-300's iokit-sysctl device is similar to the SSE-200, but
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
are the same on all SSE versions and so need no code change at all.
Putting both of these categories together covers:
0x0 SECDBGSTAT
0x4 SECDBGSET
0x8 SECDBGCLR
0xc SCSECCTRL
0x10 CLK_CFG0 -- this is like SSE-200 FCLK_DIV but with a
different set of clocks being controlled; our implementation
is a dummy reads-as-written anyway
0x14 CLK_CFG1 -- similar to SSE-200 SYSCLK_DIV; our implementation
is a dummy
0x18 CLK_FORCE -- similar to SSE-200 but different bit allocations;
we have a dummy implementation
0x100 RESET_SYNDROME -- bit allocation differs from SSE-200 but our
implementation is a dummy
0x104 RESET_MASK -- bit allocation differs from SSE-200 but our
implementation is a dummy
0x108 SWRESET
0x10c GRETREG
0x200 PDCM_PD_SYS_SENSE -- some bit allocations differ, but our
implementation is a dummy
We also need to migrate the state of these registers which are shared
between the SSE-200 and SSE-300, so update the vmstate 'needed'
function to do this.

For SSE-300, the SYSINFO register block has two new registers:
* SYS_CONFIG1 indicates the config for a potential CPU2 and CPU3;
since the SSE-300 can only be configured with a single CPU it
is always zero
* IIDR is the subsystem implementation identity register;
its value is set by the SoC integrator, so we plumb this in from
the armsse.c code as we do with SYS_VERSION and SYS_CONFIG

Remove the is_sse200 flag in favour of just directly testing the new
sse_version field.
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
reaching the "unreachable" default cases is that armsse.c doesn't
yet pass us an ARMSSE_SSE300 version.)

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".

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.

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.
