Initial definitions for a simple machine using an AST2600 SoC (Cortex

The Cortex CPU and its interrupt controller are too complex to handle
in the common Aspeed SoC framework. We introduce a new Aspeed SoC
class with instance_init and realize handlers to handle the differences
with the AST2400 and the AST2500 SoCs. This will add extra work to
keep in sync both models with future extensions but it makes the code
clearer.

Switch the musicpal code away from bottom-half based ptimers to
the new transaction-based ptimer API. This just requires adding
begin/commit calls around the various places that modify the ptimer
state, and using the new ptimer_init() function to create the timer.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

Message-id: 20191008171740.9679-6-peter.maydell@linaro.org
Currently the ptimer design uses a QEMU bottom-half as its
mechanism for calling back into the device model using the
ptimer when the timer has expired. Unfortunately this design
is fatally flawed, because it means that there is a lag
between the ptimer updating its own state and the device
callback function updating device state, and guest accesses
to device registers between the two can return inconsistent
device state.
We want to replace the bottom-half design with one where
the guest device's callback is called either immediately
(when the ptimer triggers by timeout) or when the device
model code closes a transaction-begin/end section (when the
ptimer triggers because the device model changed the
ptimer's count value or other state). As the first step,
rename ptimer_init() to ptimer_init_with_bh(), to free up
the ptimer_init() name for the new API. We can then convert
all the ptimer users away from ptimer_init_with_bh() before
removing it entirely.
(Commit created with
git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/'
and three overlong lines folded by hand.)

Currently, when a notifier is attempted to be registered and its
flags are not supported (especially the MAP one) by the IOMMU MR,
we generally abruptly exit in the IOMMU code. The failure could be
handled more nicely in the caller and especially in the VFIO code.
So let's allow memory_region_register_iommu_notifier() to fail as
well as notify_flag_changed() callback.
All sites implementing the callback are updated. This patch does
not yet remove the exit(1) in the amd_iommu code.
in SMMUv3 we turn the warning message into an error message saying
that the assigned device would not work properly.

If we're booting a Linux kernel directly into Non-Secure
state on a CPU which has Secure state, then make sure we
set the NSACR CP11 and CP10 bits, so that Non-Secure is allowed
to access the FPU. Otherwise an AArch32 kernel will UNDEF as
soon as it tries to use the FPU.
It used to not matter that we didn't do this until commit
fc1120a7f5, where we implemented actually honouring
these NSACR bits.
The problem only exists for CPUs where EL3 is AArch32; the
equivalent AArch64 trap bits are in CPTR_EL3 and are "0 to
not trap, 1 to trap", so the reset value of the register
permits NS access, unlike NSACR.

Child properties form the composition tree. All objects need to be
a child of another object. Objects can only be a child of one object.
Respect this with the i.MX SoC, to get a cleaner composition tree.

Both object_initialize() and qdev_set_parent_bus() increase the
reference counter of the new object, so one of the references has
to be dropped afterwards to get the reference counting right.
In machine model code this refcount leak is not particularly
problematic because (unlike devices) machines will never be
created on demand via QMP, and they are never destroyed.
But in any case let's use the new sysbus_init_child_obj() instead
to get the reference counting here right.

As explained in commit aff39be0ed:
Both functions, object_initialize() and object_property_add_child()
increase the reference counter of the new object, so one of the
references has to be dropped afterwards to get the reference
counting right. Otherwise the child object will not be properly
cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the
reference counting here right.

An IOVA/ASID invalidation is notified to all IOMMU Memory Regions
through smmuv3_inv_notifiers_iova/smmuv3_notify_iova.
When the notification occurs it is possible that some of the
PCIe devices associated to the notified regions do not have a
valid stream table entry. In that case we output a LOG_GUEST_ERROR
message, for example:
invalid sid=<SID> (L1STD span=0)
"smmuv3_notify_iova error decoding the configuration for iommu mr=<MR>
This is unfortunate as the user gets the impression that there
are some translation decoding errors whereas there are not.
This patch adds a new field in SMMUEventInfo that tells whether
the detection of an invalid STE must lead to an error report.
invalid_ste_allowed is set before doing the invalidations and
kept unset on actual translation.
The other configuration decoding error messages are kept since if the
STE is valid then the rest of the config must be correct.

Add 4.2 machine types for arm/i440fx/q35/s390x/spapr.
For i440fx and q35, unversioned cpu models are still translated
to -v1, as 0788a56bd1 ("i386: Make unversioned CPU models be
aliases") states this should only transition to the latest cpu
model version in 4.3 (or later).
