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.

The FMC controller on the Aspeed SoCs support DMA to access the flash
modules. It can operate in a normal mode, to copy to or from the flash
module mapping window, or in a checksum calculation mode, to evaluate
the best clock settings for reads.
The model introduces two custom address spaces for DMAs: one for the
AHB window of the FMC flash devices and one for the DRAM. The latter
is populated using a "dram" link set from the machine with the RAM
container region.

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.

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.

In my "build everything" tree, changing sysemu/reset.h triggers a
recompile of some 2600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
The main culprit is hw/hw.h, which supposedly includes it for
convenience.
Include sysemu/reset.h only where it's needed. Touching it now
recompiles less than 200 objects.

In commit e6b2b20d97 we made the boot loader code try to avoid
putting the initrd on top of the kernel. However the expression used
to calculate the start of the initrd:
info->initrd_start = info->loader_start +
MAX(MIN(info->ram_size / 2, 128 * 1024 * 1024), kernel_size);
incorrectly uses 'kernel_size' as the offset within RAM of the
highest address to avoid. This is incorrect because the kernel
doesn't start at address 0, but slightly higher than that. This
means that we can still incorrectly end up overlaying the initrd on
the kernel in some cases, for example:
* The kernel's image_size is 0x0a7a8000
* The kernel was loaded at 0x40080000
* The end of the kernel is 0x4A828000
* The DTB was loaded at 0x4a800000
To get this right we need to track the actual highest address used
by the kernel and use that rather than kernel_size. We already
set image_low_addr and image_high_addr for ELF images; set them
also for the various other image types we support, and then use
image_high_addr as the lowest allowed address for the initrd.
(We don't use image_low_addr, but we set it for consistency
with the existing code path for ELF files.)

The i.MX6UL always has a single Cortex-A7 CPU (we set FSL_IMX6UL_NUM_CPUS
to 1 in line with this). This means that all the code in fsl-imx6ul.c to
handle multiple CPUs is dead code, and Coverity is now complaining that
it is unreachable (CID 1403008, 1403011).
Remove the unreachable code and the only-executes-once loops,
and replace the single-entry cpu[] array in the FSLIMX6ULState
with a simple cpu member.

Using the whole 128 MiB flash in non-secure mode is not working because
virt_flash_fdt() expects the same address for secure_sysmem and sysmem.
This is not correctly handled by caller because it forwards NULL for
secure_sysmem in non-secure flash mode.
Fixed by using sysmem when secure_sysmem is NULL.

In the virt machine, we support TrustZone being either present or
absent, and so the code must deal with the secure_sysmem pointer
possibly being NULL. In the sbsa-ref machine, TrustZone is always
present, but some code and comments copied from virt still treat
it as possibly not being present.
This causes Coverity to complain (CID 1407287) that we check
secure_sysmem for being NULL after an unconditional dereference.
Simplify the code so that instead of initializing the variable
to NULL, unconditionally assigning it, and then testing it for NULL,
we just initialize it correctly in the variable declaration and
then assume it to be non-NULL. We also delete a comment which
only applied to the non-TrustZone config.

Legacy '-numa node,mem' option has a number of issues and mgmt often
defaults to it. Unfortunately it's no possible to replace it with
an alternative '-numa memdev' without breaking migration compatibility.
What's possible though is to deprecate it, keeping option working with
old machine types only.
In order to help users to find out if being deprecated CLI option
'-numa node,mem' is still supported by particular machine type, add new
"numa-mem-supported" property to output of query-machines.
"numa-mem-supported" is set to 'true' for machines that currently support
NUMA, but it will be flipped to 'false' later on, once deprecation period
expires and kept 'true' only for old machine types that used to support
the legacy option so it won't break existing configuration that are using
it.

A local variable of the same name would be introduced in the declaration

For AArch64, the existing "virt" machine is primarily meant to
run on KVM and execute virtualization workloads, but we need an
environment as faithful as possible to physical hardware, for supporting
firmware and OS development for physical Aarch64 machines.
This patch introduces new machine type 'sbsa-ref' with main features:
- Based on 'virt' machine type.
- A new memory map.
- CPU type cortex-a57.
- EL2 and EL3 are enabled.
- GIC version 3.
- System bus AHCI controller.
- System bus EHCI controller.
- CDROM and hard disc on AHCI bus.
- E1000E ethernet card on PCIE bus.
- VGA display adaptor on PCIE bus.
- No virtio devices.
- No fw_cfg device.
- No ACPI table supplied.
- Only minimal device tree nodes.
Arm Trusted Firmware and UEFI porting to this are done accordingly,
and the firmware should supply ACPI tables to the guest OS. The
minimal device tree nodes supplied by QEMU for this platform are only
to pass the dynamic info reflecting command line input to firmware,
not for loading the guest OS.
To make the review easier, this task is split into two patches, the
fundamental skeleton part and the peripheral devices part; this patch is
the first part.

The ast2500 uses the watchdog to reset the SDRAM controller. This
operation is usually performed by u-boot's memory training procedure,
and it is enabled by setting a bit in the SCU and then causing the
watchdog to expire. Therefore, we need the watchdog to be able to
access the SCU's register space.
This causes the watchdog to not perform a system reset when the bit is
set. In the future it could perform a reset of the SDMC model.

The RAM memory region is defined after the SoC is realized when the
SDMC controller has checked that the defined RAM size for the machine
is correct. This is problematic for controller models requiring a link
on the RAM region, for DMA support in the SMC controller for instance.
Introduce a container memory region for the RAM that we can link into
the controllers early, before the SoC is realized. It will be
populated with the RAM region after the checks have be done.
