a5a5778622 ppc/spapr|pnv: Remove SAO from pa-features
SAO is a page table attribute that strengthens the memory ordering of
accesses. QEMU with MTTCG does not implement this, so clear it in
ibm,pa-features. This is an obscure feature that has been removed from
POWER10 ISA v3.1, there isn't much concern with removing it.

78abf93cc7 mac_newworld: change timebase frequency from 100MHz to 25MHz for mac99 machine
MacOS X uses multiple techniques for calibrating timers depending upon the detected
hardware. One of these calibration routines compares the change in the timebase
against the KeyLargo timer and uses this to recalculate the clock frequency,
timebase frequency and bus frequency if the calibration exceeds certain limits.
This recalibration occurs despite the correct values being passed via the device
tree, and is likely due to buggy firmware on some hardware.

The timebase frequency of 100MHz was set way back in 2005 by commit fa296b0fb4
("PIC fix - changed back TB frequency to 100 MHz") and with this value on a
mac99,via=pmu machine the OSX 10.2 timer calibration incorrectly calculates the
bus frequency as 400MHz instead of 100MHz. The most noticeable side-effect is
the UI appears sluggish and not very responsive for normal use.

Change the timebase frequency from 100MHz to 25MHz which matches that of a real
G4 AGP machine (the closest match to QEMU's mac99 machine) and allows OSX 10.2
to correctly detect all of the clock frequency, timebase frequency and bus
frequency.

Tested on various MacOS images from OS 9.2 through to OSX 10.4, along with Linux
and NetBSD and I was unable to find any regressions from this change.

cde2ba34a9 ppc/pnv: Implement the ChipTOD to Core transfer
One of the functions of the ChipTOD is to transfer TOD to the Core
(aka PC - Pervasive Core) timebase facility.

The ChipTOD can be programmed with a target address to send the TOD
value to. The hardware implementation seems to perform this by
sending the TOD value to a SCOM address.

This implementation grabs the core directly and manipulates the
timebase facility state in the core. This is a hack, but it works
enough for now. A better implementation would implement the transfer
to the PnvCore xscom register and drive the timebase state machine
from there.

9a69950feb ppc/pnv: Add POWER9/10 chiptod model
The ChipTOD (for Time-Of-Day) is a chip pervasive facility in IBM POWER
(powernv) processors that keeps a time of day clock.

In particular for this model are facilities that initialise and start
the time of day clock, and that synchronise that clock to cores on the
chip, and to other chips. In this way, all cores on all chips can
synchronise timebase (TB).

This model implements functionality sufficient to run the skiboot
chiptod synchronisation procedure (with the following core timebase
state machine implementation). It does not modify the TB in the cores
where the real hardware would, because the QEMU ppc timebase
implementation is always synchronised acros all cores.

7b85f008b6 ppc/pnv: Use resettable interface to reset child I2C buses
The QEMU I2C buses and devices use the resettable
interface for resetting while the PNV I2C controller
and parent buses and devices have not yet transitioned
to this new interface and use the old reset strategy.
This was preventing the I2C buses and devices wired
to the PNV I2C controller from being reset.

The short term fix for this is to have the PNV I2C
Controller's reset function explicitly call the resettable
interface function, bus_cold_reset(), on all child
I2C buses.

The long term fix should be to transition all PNV parent
devices and buses to use the resettable interface so that
all child buses and devices are automatically reset.

6f86885a74 ppc/pnv: Wire up pca9552 GPIO pins for PCIe hotplug power control
For power10-rainier, a pca9552 device is used for PCIe slot hotplug
power control by the Power Hypervisor code.  The code expects that
some time after it enables power to a PCIe slot by asserting one of
the pca9552 GPIO pins 0-4, it should see a "power good" signal asserted
on one of pca9552 GPIO pins 5-9.

To simulate this behavior, we simply connect the GPIO outputs for
pins 0-4 to the GPIO inputs for pins 5-9.

Each PCIe slot is assigned 3 GPIO pins on the pca9552 device, for
control of up to 5 PCIe slots.  The per-slot signal names are:

   SLOTx_EN.......PHYP uses this as an output to enable
                  slot power.  We connect this to the
                  SLOTx_PG pin to simulate a PGOOD signal.
   SLOTx_PG.......PHYP uses this as in input to detect
                  PGOOD for the slot.  For our purposes
                  we just connect this to the SLOTx_EN
                  output.
   SLOTx_Control..PHYP uses this as an output to prevent
                  a race condition in the real hotplug
                  circuitry, but we can ignore this output
                  for simulation.

source set to pci_ss[] which is common to all targets: the
object is built once.

Declare PPC4XX_PCI selector in pci-host/Kconfig.

This is a preparation for implementing relocation and toggling of SuperI/O

deactivated, so in case if no -bios is given, let the machine configure those
functions the same way Pegasos II firmware would do.

5bfb75f152 target/ppc/cpu-models: Rename power5+ and power7+ for new QOM naming rules
The character "+" is now forbidden in QOM device names (see commit
b447378e12 - "Limit type names to alphanumerical and some few special
characters"). For the "power5+" and "power7+" CPU names, there is
currently a hack in type_name_is_valid() to still allow them for
compatibility reasons. However, there is a much nicer solution for this:
Simply use aliases! This way we can still support the old names without
the need for the ugly hack in type_name_is_valid().

Previously, the first PCI NIC would be placed in PCI slot 3 and the rest
would be dynamically assigned. Even if the user overrode the default NIC
type and made it something other than PCNet.

Now, the first PCNet NIC (that is, anything not explicitly specified
to be anything different) will go to slot 3 even if it isn't the first
NIC specified on the command line. And anything else will be dynamically
assigned.

195801d700 system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()
The Big QEMU Lock (BQL) has many names and they are confusing. The
actual QemuMutex variable is called qemu_global_mutex but it's commonly
referred to as the BQL in discussions and some code comments. The
locking APIs, however, are called qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread().

The "iothread" name is historic and comes from when the main thread was
split into into KVM vcpu threads and the "iothread" (now called the main
loop thread). I have contributed to the confusion myself by introducing
a separate --object iothread, a separate concept unrelated to the BQL.

The "iothread" name is no longer appropriate for the BQL. Rename the
locking APIs to:
- void bql_lock(void)
- void bql_unlock(void)
- bool bql_locked(void)

There are more APIs with "iothread" in their names. Subsequent patches
will rename them. There are also comments and documentation that will be
updated in later patches.

commit 5de164304a ("arm: Allow secondary KVM CPUs to be booted

c1b701587e ("target/arm: Move start-powered-off property to generic
CPUState"). Since all CPUs have it, no need to check whether it is
available. Updating this property can't fail, so use &error_abort.
