The reset value of IPIDR should be zero for Freescale chipset, per
the following 2 manuals I checked:
- P2020RM (https://www.nxp.com/webapp/Download?colCode=P2020RM)
- P4080RM (https://www.nxp.com/webapp/Download?colCode=P4080RM)
Currently it is set to 1, which leaves the IPI enabled on core 0
after power-on reset. Such may cause unexpected interrupt to be
delivered to core 0 if the IPI is triggered from core 0 to other
cores later.

During sbsa acs level 3 testing, it is seen that the GIC maintenance
interrupts are not triggered and the related test cases fail. This
is because we were incorrectly passing the value of the MISR register
(from maintenance_interrupt_state()) to qemu_set_irq() as the level
argument, whereas the device on the other end of this irq line
expects a 0/1 value.
Fix the logic to pass a 0/1 level indication, rather than a
0/not-0 value.

Instead of having the NVIC device provide a single sysbus memory
region covering the whole of the "System PPB" space, which implements
the default behaviour for unimplemented ranges and provides the NS
alias window to the sysregs as well as the main sysreg MR, move this
handling to the container armv7m device. The NVIC now provides a
single memory region which just implements the system registers.
This consolidates all the handling of "map various devices in the
PPB" into the armv7m container where it belongs.

SysTick device objects; move them into the ARMv7M container object
instead, as part of consolidating the "create the devices which are
built into an M-profile CPU and map them into their architected
locations in the address space" work into one place.
This involves temporarily creating a duplicate copy of the

v7m_sysreg_ns_*), but we will delete the NVIC's copy of this code in
a subsequent patch.

Quoting Peter Maydell:
These MEMTX_* aren't from the memory transaction API functions;
they're just being used by gicd_readl() and friends as a way to
indicate a success/failure so that the actual MemoryRegionOps
read/write fns like gicv3_dist_read() can log a guest error.
Arguably this is a bit of a misuse of the MEMTX_* constants and
perhaps we should have gicd_readl etc return a bool instead.
Follow his suggestion and replace the MEMTX_* constants by
boolean values, simplifying a bit the gicv3_dist_read() /
gicv3_dist_write() handlers.

`muldiv64` would overflow in cases where the final 96-bit value does not
fit in a `uint64_t`. This would result in small values that cause an
interrupt to be triggered much sooner than intended.
The overflow can be detected in most cases by checking if the new value is
smaller than the previous value. If the final result is larger than
`diff` it is either correct or it doesn't matter as it is effectively
infinite anyways.
`next` is an `uint64_t` value, but `timer_mod` takes an `int64_t`. This
resulted in high values such as `UINT64_MAX` being converted to `-1`,
which caused an immediate timer interrupt.
By limiting `next` to `INT64_MAX` no overflow will happen while the
timer will still be effectively set to "infinitely" far in the future.

The ISCR.ISRPENDING bit is set when an external interrupt is pending.
This is true whether that external interrupt is enabled or not.
This means that we can't use 's->vectpending == 0' as a shortcut to
"ISRPENDING is zero", because s->vectpending indicates only the
highest priority pending enabled interrupt.
Remove the incorrect optimization so that if there is no pending

icv_eoir_write() and icv_dir_write() ignore invalid virtual IRQ numbers
(like LPIs). The issue is that these functions check against the number
of implemented IRQs (QEMU's default is num_irq=288) which can be lower
than the maximum virtual IRQ number (1020 - 1). The consequence is that
if a hypervisor creates an LR for an IRQ between 288 and 1020, then the
guest is unable to deactivate the resulting IRQ. Note that other
functions that deal with large IRQ numbers, like icv_iar_read, check
against 1020 and not against num_irq.
Fix the checks by using GICV3_MAXIRQ (1020) instead of the number of
implemented IRQs.

Commit 382c7160d1 ("hw/intc/arm_gicv3_cpuif: Fix EOIR write access
check logic") added an assert_not_reached() if the guest writes the EOIR
register while no interrupt is active.
It turns out some software does this: EDK2, in
GicV3ExitBootServicesEvent(), unconditionally write EOIR for all
interrupts that it manages. This now causes QEMU to abort when running
UEFI on a VM with GICv3. Although it is UNPREDICTABLE behavior and EDK2
does need fixing, the punishment seems a little harsh, especially since
icc_eoir_write() already tolerates writes of nonexistent interrupt
numbers. Display a guest error and tolerate spurious EOIR writes.

In icc_eoir_write() we assume that we can identify the group of the
IRQ being completed based purely on which register is being written
to and the current CPU state, and that "CPU state matches group
indicated by register" is the only necessary access check.
This isn't correct: if the CPU is not in Secure state then EOIR1 will
only complete Group 1 NS IRQs, but if the CPU is in EL3 it can
complete both Group 1 S and Group 1 NS IRQs. (The pseudocode
ICC_EOIR1_EL1 makes this clear.) We were also missing the logic to
prevent EOIR0 writes completing G0 IRQs when they should not.
Rearrange the logic to first identify the group of the current
highest priority interrupt and then look at whether we should
complete it or ignore the access based on which register was accessed
and the state of the CPU. The resulting behavioural change is:
* EL3 can now complete G1NS interrupts
* G0 interrupt completion is now ignored if the GIC
and the CPU have the security extension enabled and
the CPU is not secure

Target lm32 was deprecated in commit d849800512, v5.2.0. See there
for rationale.
Some of its code lives on in device models derived from milkymist
ones: hw/char/digic-uart.c and hw/display/bcm2835_fb.c.

Update the OpenTitan interrupt layout to match the latest OpenTitan
bitstreams. This involves changing the Ibex PLIC memory layout and the
UART interrupts.

Here's the first ppc pull request for qemu-6.1. It has a wide variety
of stuff accumulated during the 6.0 freeze. Highlights are:
* Multi-phase reset cleanups for PAPR
* Preliminary cleanups towards allowing !CONFIG_TCG for the ppc target
* Cleanup of AIL logic and extension to POWER10
* Further improvements to handling of hot unplug failures on PAPR
* Allow much larger numbers of CPU on pseries
* Support for the H_SCM_HEALTH hypercall
* Add support for the Pegasos II board
* Substantial cleanup to hflag handling
* Assorted minor fixes and cleanups

The h_int_reset() function resets the XIVE interrupt controller via
device_legacy_reset(). We know that the interrupt controller does
not have a qbus of its own, so the new device_cold_reset() function
(which resets both the device and its child buses) is equivalent here
to device_legacy_reset() and we can just switch to the new API.
