In the armv7m object, handle clock inputs that aren't connected.
This is always an error for 'cpuclk'. For 'refclk' it is OK for this
to be disconnected, but we need to handle it by not trying to connect
a sourceless-clock to the systick device.
This fixes a bug where on the mps2-an521 and similar boards (which
do not have a refclk) the systick device incorrectly reset with
SYST_CSR.CLKSOURCE 0 ("use refclk") rather than 1 ("use CPU clock").

Currently there is no way for a board model's Kconfig stanza to
say "I have an i2c bus which the user can plug an i2c device into,
build all the free-standing i2c devices". The Kconfig mechanism
for this is the "device group". Add an I2C_DEVICES group along
the same lines as the existing PCI_DEVICES. Simple free-standing
i2c devices which a user might plausibly want to be able to
plug in on the QEMU commandline should have
default y if I2C_DEVICES
and board models which have an i2c bus that is user-accessible
should use
imply I2C_DEVICES
to cause those pluggable devices to be built.
In this commit we mark only a fairly conservative set of i2c devices
as belonging to the I2C_DEVICES group: the simple sensors and RTCs
(not including PMBus devices or devices which need GPIO lines to be
connected).

This implements the Nested KVM HV hcall API for spapr under TCG.
The L2 is switched in when the H_ENTER_NESTED hcall is made, and the
L1 is switched back in returned from the hcall when a HV exception
is sent to the vhyp. Register state is copied in and out according to
the nested KVM HV hcall API specification.
The hdecr timer is started when the L2 is switched in, and it provides
the HDEC / 0x980 return to L1.
The MMU re-uses the bare metal radix 2-level page table walker by
using the get_pate method to point the MMU to the nested partition
table entry. MMU faults due to partition scope errors raise HV
exceptions and accordingly are routed back to the L1.
The MMU does not tag translations for the L1 (direct) vs L2 (nested)
guests, so the TLB is flushed on any L1<->L2 transition (hcall entry
and exit).

Introduce virtual hypervisor methods that can support a "Nested KVM HV"
implementation using the bare metal 2-level radix MMU, and using HV
exceptions to return from H_ENTER_NESTED (rather than cause interrupts).
HV exceptions can now be raised in the TCG spapr machine when running a
nested KVM HV guest. The main ones are the lev==1 syscall, the hdecr,
hdsi and hisi, hv fu, and hv emu, and h_virt external interrupts.
HV exceptions are intercepted in the exception handler code and instead
of causing interrupts in the guest and switching the machine to HV mode,
they go to the vhyp where it may exit the H_ENTER_NESTED hcall with the
interrupt vector numer as return value as required by the hcall API.
Address translation is provided by the 2-level page table walker that is
implemented for the bare metal radix MMU. The partition scope page table
is pointed to the L1's partition scope by the get_pate vhc method.

If the device backend is not persistent memory for the nvdimm, there is
need for explicit IO flushes on the backend to ensure persistence.
On SPAPR, the issue is addressed by adding a new hcall to request for
an explicit flush from the guest when the backend is not pmem. So, the
approach here is to convey when the hcall flush is required in a device
tree property. The guest once it knows the device backend is not pmem,
makes the hcall whenever flush is required.
To set the device tree property, a new PAPR specific device type inheriting
the nvdimm device is implemented. When the backend doesn't have pmem=on
the device tree property "ibm,hcall-flush-required" is set, and the guest
makes hcall H_SCM_FLUSH requesting for an explicit flush. The new device
has boolean property pmem-override which when "on" advertises the device
tree property even when pmem=on for the backend. The flush function
invokes the fdatasync or pmem_persist() based on the type of backend.
The vmstate structures are made part of the spapr-nvdimm device object.
The patch attempts to keep the migration compatibility between source and
destination while rejecting the incompatibles ones with failures.

The patch adds support for the SCM flush hcall for the nvdimm devices.
To be available for exploitation by guest through the next patch. The
hcall is applicable only for new SPAPR specific device class which is
also introduced in this patch.
The hcall expects the semantics such that the flush to return with
H_LONG_BUSY_ORDER_10_MSEC when the operation is expected to take longer
time along with a continue_token. The hcall to be called again by providing
the continue_token to get the status. So, all fresh requests are put into
a 'pending' list and flush worker is submitted to the thread pool. The
thread pool completion callbacks move the requests to 'completed' list,
which are cleaned up after collecting the return status for the guest
in subsequent hcall from the guest.
The semantics makes it necessary to preserve the continue_tokens and
their return status across migrations. So, the completed flush states
are forwarded to the destination and the pending ones are restarted
at the destination in post_load. The necessary nvdimm flush specific
vmstate structures are also introduced in this patch which are to be
saved in the new SPAPR specific nvdimm device to be introduced in the
following patch.

Coroutine pool size was 64 from long ago, and the basis was organized in the commit message in 4d68e86b.
At that time, virtio-blk queue-size and num-queue were not configuable, and equivalent values were 128 and 1.
Coroutine pool size 64 was fine then.
Later queue-size and num-queue got configuable, and default values were increased.
Coroutine pool with size 64 exhausts frequently with random disk IO in new size, and slows down.
This commit adjusts coroutine pool size adaptively with new values.
This commit adds 64 by default, but now coroutine is not only for block devices,
and is not too much burdon comparing with new default.
pool size of 128 * vCPUs.

Add support for TP 4076 ("Zoned Random Write Area"), v2021.08.23
("Ratified").
This adds three new namespace parameters: "zoned.numzrwa" (number of
zrwa resources, i.e. number of zones that can have a zrwa),
"zoned.zrwas" (zrwa size in LBAs), "zoned.zrwafg" (granularity in LBAs
for flushes).

This fixes CVE-2021-3929 "locally" by denying DMA to the iomem of the

The PowerPC 601 processor is the first generation of processors to
implement the PowerPC architecture. It was designed as a bridge
processor and also could execute most of the instructions of the
previous POWER architecture. It was found on the first Macs and IBM
RS/6000 workstations.
There is not much interest in keeping the CPU model of this
POWER-PowerPC bridge processor. We have the 603 and 604 CPU models of
the 60x family which implement the complete PowerPC instruction set.

In most of the ITS command processing, we check different error
possibilities one at a time and log them appropriately. In
process_mapti() and process_mapd() we have code which checks
multiple error cases at once, which means the logging is less
specific than it could be. Split those cases up.

When handling MAPI/MAPTI, we allow the supplied interrupt ID to be
either 1023 or something in the valid LPI range. This is a mistake:
only a real valid LPI is allowed. (The general behaviour of the ITS
is that most interrupt ID fields require a value in the LPI range;
the exception is that fields specifying a doorbell value, which are
all in GICv4 commands, allow also 1023 to mean "no doorbell".)
Remove the condition that incorrectly allows 1023 here.
