The armv7m systick timer is a 24-bit decrementing, wrap-on-zero,
clear-on-write counter. Our current implementation has various
bugs and dubious workarounds in it (for instance see
https://bugs.launchpad.net/qemu/+bug/1872237).
We have an implementation of a simple decrementing counter
and we put a lot of effort into making sure it handles the
interesting corner cases (like "spend a cycle at 0 before
reloading") -- ptimer.
Rewrite the systick timer to use a ptimer rather than
a raw QEMU timer.
Unfortunately this is a migration compatibility break,
which will affect all M-profile boards.
Among other bugs, this fixes
https://bugs.launchpad.net/qemu/+bug/1872237 :
now writes to SYST_CVR when the timer is enabled correctly
do nothing; when the timer is enabled via SYST_CSR.ENABLE,
the ptimer code will (because of POLICY_NO_IMMEDIATE_RELOAD)
arrange that after one timer tick the counter is reloaded
from SYST_RVR and then counts down from there, as the
architecture requires.

The watchdog is part of NPCM7XX's timer module. Its behavior is
controlled by the WTCR register in the timer.
When enabled, the watchdog issues an interrupt signal after a pre-set
amount of cycles, and issues a reset signal shortly after that.

This peripheral has 1 free-running timer and 4 compare registers.
Only the free-running timer is implemented. Add support the
COMPARE registers (each register is wired to an IRQ).
Reference: "BCM2835 ARM Peripherals" datasheet [*]
chapter 12 "System Timer":
The System Timer peripheral provides four 32-bit timer channels
and a single 64-bit free running counter. Each channel has an
output compare register, which is compared against the 32 least
significant bits of the free running counter values. When the
two values match, the system timer peripheral generates a signal
to indicate a match for the appropriate channel. The match signal
is then fed into the interrupt controller.
This peripheral is used since Linux 3.7, commit ee4af5696720
("ARM: bcm2835: add system timer").

The NPCM730 and NPCM750 SoCs have three timer modules each holding five
timers and some shared registers (e.g. interrupt status).
Each timer runs at 25 MHz divided by a prescaler, and counts down from a
configurable initial value to zero. When zero is reached, the interrupt
flag for the timer is set, and the timer is disabled (one-shot mode) or
reloaded from its initial value (periodic mode).
This implementation is sufficient to boot a Linux kernel configured for
NPCM750. Note that the kernel does not seem to actually turn on the
interrupts.

It is the responsibility of board code for an armv7m system to set
system_clock_scale appropriately for the CPU speed of the core.
If it forgets to do this, then QEMU will hang if the guest tries
to use the systick timer in the "tick at the CPU clock frequency" mode.
We forgot that in a couple of our boards (see commits ce4f70e81e,
e7e5a9595a). Add an assertion in the systick reset method so
we don't let any new boards in with the same bug.

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

The imx_epit device has a software-controllable reset triggered by
setting the SWR bit in the CR register. An error in commit cc2722ec83
means that we will end up assert()ing if the guest does this, because
the code in imx_epit_write() starts ptimer transactions, and then
imx_epit_reset() also starts ptimer transactions, triggering
"ptimer_transaction_begin: Assertion `!s->in_transaction' failed".
The cleanest way to avoid this double-transaction is to move the
start-transaction for the CR write handling down below the check of
the SWR bit.

Define the new macro VMSTATE_INSTANCE_ID_ANY for callers who wants to
auto-generate the vmstate instance ID. Previously it was hard coded
as -1 instead of this macro. It helps to change this default value in
the follow up patches. No functional change.

Since i8254_common.c calls isa_register_ioport() from "hw/isa/isa.h"
we can not select it when ISA_BUS is disabled. Add a 'depends on'
clause.

The Aspeed Watchdog and Timer models have a link pointing to the SCU
controller model of the machine.
Change the "scu" property definition so that it explicitly sets the
pointer. The property isn't optional : not being able to set the link
is a bug and QEMU should rather abort than exit in this case.

These devices implemented their load_state_old() handler 10 years
ago, previous to QEMU v0.12.
Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines,
we can drop this code.
Note: the mips_r4k machine started to use the i8254 device just
after QEMU v0.5.0, but the MIPS machine types are not versioned,
so there is no migration compatibility issue removing this handler.
