The current code assumes that we don't need to exit the TB
if a Data Cache Flush or Insert has happend. However, as we
have a shared Data/Instruction TLB, a Data cache flush also
flushes Instruction TLB entries, and a Data cache TLB insert
might also evict a Instruction TLB entry.
So exit the TB in all cases if Instruction translation is enabled.

Assume the following sequence:
pitlbe r0(sr0,r0)
iitlba r4,(sr0,r0)
ldil L%3000000,r5
iitlbp r5,(sr0,r0)
This will purge the whole TLB and add an entry for page 0. However
the current TLB implementation in helper_iitlba() will store to
the last empty TLB entry, while helper_iitlbp() will write to the
first empty entry. That is because an empty entry will match address
0 in helper_iitlba()

Some machines have an SDHCI device, but no PCI. To be able to
compile hw/sd/sdhci.c without CONFIG_PCI, we must not call functions
like pci_get_address_space() and pci_allocate_irq() there. Thus
move the PCI-related code into a separate file.
This is required for the new Kconfig-like build system, e.g. it is
needed if a user wants to compile a QEMU binary with just one machine
that has SDHCI, but no PCI, like the ARM "raspi" machines for example.

Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state; the
management of global_qtest is even harder to follow because
it was masked behind set_context().
Instead, explicitly pass QTestState* around (generally, by
reusing the member already present in ahci->parent QOSState),
and call explicit qtest_* functions on all places that
interact with a monitor.
We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).

The new pseries-4.0 machine type defaults to enabling Spectre/Meltdown
mitigations. Unfortunately those mitigations aren't implemented for TCG
because we're not yet sure if they're necessary or how to implement them.
We don't fail fatally, but we do warn in this case, because it is quite
plausible that Spectre/Meltdown can be exploited through TCG (at least for
the guest to get access to the qemu address space).
This create noise in our testcases though. So, modify the affected tests
to explicitly disable the mitigations to suppress these warnings.

The qemu coding standard is to use CamelCase for type and structure names,
and the pseries code follows that... sort of. There are quite a lot of
places where we bend the rules in order to preserve the capitalization of
internal acronyms like "PHB", "TCE", "DIMM" and most commonly "sPAPR".
That was a bad idea - it frequently leads to names ending up with hard to
read clusters of capital letters, and means they don't catch the eye as
type identifiers, which is kind of the point of the CamelCase convention in
the first place.
In short, keeping type identifiers look like CamelCase is more important
than preserving standard capitalization of internal "words". So, this
patch renames a heap of spapr internal type names to a more standard
CamelCase.
In addition to case changes, we also make some other identifier renames:
VIOsPAPR* -> SpaprVio*
The reverse word ordering was only ever used to mitigate the capital
cluster, so revert to the natural ordering.
VIOsPAPRVTYDevice -> SpaprVioVty
VIOsPAPRVLANDevice -> SpaprVioVlan
Brevity, since the "Device" didn't add useful information
sPAPRDRConnector -> SpaprDrc
sPAPRDRConnectorClass -> SpaprDrcClass
Brevity, and makes it clearer this is the same thing as a "DRC"
mentioned in many other places in the code
This is 100% a mechanical search-and-replace patch. It will, however,
conflict with essentially any and all outstanding patches touching the
spapr code.

The POWER9 processor does not support per-core frequency control. The
cores are arranged in groups of four, along with their respective L2
and L3 caches, into a structure known as a Quad. The frequency must be
managed at the Quad level.
Provide a basic Quad model to fake the settings done by the firmware
on the Non-Cacheable Unit (NCU). Each core pair (EX) needs a special
BAR setting for the TIMA area of XIVE because it resides on the same
address on all chips.

The LPC Controller on POWER9 is very similar to the one found on
POWER8 but accesses are now done via on MMIOs, without the XSCOM and
ECCB logic. The device tree is populated differently so we add a
specific POWER9 routine for the purpose.
SerIRQ routing is yet to be done.

The ISA bus has a different DT nodename on POWER9. Compute the name
when the PnvChip is realized, that is before it is used by the machine
to populate the device tree with the ISA devices.

The PowerNV LPC Controller exposes different sets of registers for
each of the functional units it encompasses, among which the OPB
(On-Chip Peripheral Bus) Master and Arbitrer and the LPC HOST
Controller.
The mapping addresses of each register range are correct but the sizes
are too large. Fix the sizes and define the OPB Arbitrer range to fill
the gap between the OPB Master registers and the LPC HOST Controller
registers.

The PSI bridge on POWER9 is very similar to POWER8. The BAR is still
set through XSCOM but the controls are now entirely done with MMIOs.
More interrupts are defined and the interrupt controller interface has
changed to XIVE. The POWER9 model is a first example of the usage of
the notify() handler of the XiveNotifier interface, linking the PSI
XiveSource to its owning device model.

To ease the introduction of the PSI bridge model for POWER9, abstract
the POWER chip differences in a PnvPsi class model and introduce a
specific Pnv8Psi type for POWER8. POWER8 interface to the interrupt
controller is still XICS whereas POWER9 uses the new XIVE model.

set_cpu_vsr{l,h}()
Now that all VSX registers are stored in host endian order, there is no need
to go via different accessors depending upon the register number. Instead we
introduce vsr64_offset() and use it directly from within get_cpu_vsr{l,h}() and
set_cpu_vsr{l,h}().
This also allows us to rewrite avr64_offset() and fpr_offset() in terms of the
new vsr64_offset() function to more clearly express the relationship between the
VSX, FPR and VMX registers, and also remove vsrl_offset() which is no longer
required.

endian order
When VSX support was initially added, the fpr registers were added at
offset 0 of the VSR register and the vsrl registers were added at offset
1. This is in contrast to the VMX registers (the last 32 VSX registers) which
are stored in host-endian order.
Switch the fpr/vsrl registers so that the lower 32 VSX registers are now also
stored in host endian order to match the VMX registers. This ensures that TCG
vector operations involving mixed VMX and VSX registers will function
correctly.

get_avr64()/set_avr64()
By using the VsrD macro in avr64_offset() the same offset calculation can be
used regardless of the host endian. This allows get_avr64() and set_avr64() to
be simplified accordingly.

All TCG vector operations require pointers to the base address of the vector
rather than separate access to the top and bottom 64-bits. Convert the VMX TCG
instructions to use a new avr_full_offset() function instead of avr64_offset()
which can then itself be written as a simple wrapper onto vsr_full_offset().
This same function can also reused in cpu_avr_ptr() to avoid having more than
one copy of the offset calculation logic.
