Add a "virtualization" property to the vexpress-a15 board,
controlling presence of EL2. As with EL3, we default to
enabling it, but the user can disable it if they have an
older guest which can't cope with it being present.

Don't request that the arm_load_kernel() code should boot in secure
state if the CPU doesn't have a secure state. Currently this
doesn't make a difference because the boot.c code only examines
the secure_boot flag in code guarded by an ARM_FEATURE_EL3 check,
but upcoming changes for supporting booting into Hyp mode will
change that.

For the A15MPCore internal peripheral object, we handle GIC
security extensions support by checking whether the CPUs
have EL3 enabled; if so then we enable it also on the GIC.
Handle the virtualization extensions in the same way: if the
CPU has EL2 then enable it on the GIC and wire up the
virtualization-specific memory regions and the maintenance
interrupt.

Reduce the size of the per-cpu GICH memory regions from 0x1000
to 0x200. The registers only cover 0x200 bytes, and the Cortex-A15
wants to map them at a spacing of 0x200 bytes apart. Having the
region be too large interferes with mapping them like that, so
reduce it.

The PIIX4 hardware has block transfer buffer always enabled in
the hardware, but the i801 does not. Add a parameter to pm_smbus_init
to force on the block transfer so the PIIX4 handler can enable this
by default, as it was disabled by default before.

Change 880b1ffe6ec2f0ae "smbus: do not immediately complete commands"
changed pm_smbus to delay setting the host busy bit until the status
register was read, to work around a bug in AMIBIOS. Unfortunately,
when interrupts are enabled, the status register will never get read
and the processing will never happen.
Modify the code to only delay setting the host busy bit if interrupts
are not enabled.

The I2C block transfer commands was not implemented correctly, it
read a length byte and such like it was an smbus transfer.
So fix the smbus_read_block() and smbus_write_block() functions
so they can properly handle I2C transfers, and normal SMBus
transfers (for upcoming changes). Pass in a transfer size and
a bool to know whether to use the size byte (like SMBus) or use
the length given (like I2C).

We can assign and verify the address before realizing and trying to plug.
reading/writing the address property should never fail for DIMMs, so let's
reduce error handling a bit by using &error_abort. Getting access to the
memory region now might however fail. So forward errors from
get_memory_region() properly.
As all memory devices should use the alignment of the underlying memory
region for guest physical address asignment, do detection of the
alignment in pc_dimm_pre_plug(), but allow pc.c to overwrite the
alignment for compatibility handling.

All applicable memory regions always have an alignment > 0. All memory
backends result in file_ram_alloc() or qemu_anon_ram_alloc() getting
called, setting the alignment to > 0.
So a PCDIMM memory region always has an alignment > 0. NVDIMM copy the
alignment of the original memory memory region into the handcrafted memory
region that will be used at this place.
So the check for 0 can be dropped and we can reduce the special
handling.
Dropping this check makes factoring out of alignment handling easier as
compat handling only has to look at pcmc->enforce_aligned_dimm and not
care about the alignment of the memory region.

The vmstate for isa_ipmi_bt was referencing into the bt structure,
instead create a bt structure separate and use that.
The version 1 of the BT transfer was fairly broken, if a migration
occured during an IPMI operation, it is likely the migration would
be corrupted because I misunderstood the VMSTATE_VBUFFER_UINT32()
handling, I thought it handled transferring the length field,
too. So I just remove support for that. I doubt anyone is using
it at this point.
This also removes the transfer of use_irq, since that should come
from configuration.

There is currently a funny problem with the "mc146818rtc" device:
1) Start QEMU like this:
qemu-system-ppc64 -M pseries -S
2) At the HMP monitor, enter "info qom-tree". Note that there is an
entry for "/rtc (spapr-rtc)".
3) Introspect the mc146818rtc device like this:
device_add mc146818rtc,help
4) Run "info qom-tree" again. The "/rtc" entry is gone now!
The rtc_finalize() function of the mc146818rtc device has two bugs: First,
it tries to remove a "rtc" property, while the rtc_realizefn() added a
"rtc-time" property instead. And second, it should have been done in an
unrealize function, not in a finalize function, to avoid that this causes
problems during introspection.
But since adding aliases to the global machine state should not be done
from a device's realize function anyway, let's rather fix this issue
by moving the creation of the alias to the code that creates the device
(and thus is run from the machine init functions instead), i.e. the
mc146818_rtc_init() function for most machines. The prep machines are
special, since the mc146818rtc device is created here in the realize
function of the i82378 device. Since we certainly don't want to add the
alias there, we add it to some code that is called from the ibm_40p_init()
machine init function instead.
Since the alias is now only created during the machine init, we can remove
the object_property_del() completely.

just need adding a fall through comment. This is exactly what this

ppc patch queue 2018-08-21
Here's my first ppc & spapr pull request for qemu-3.1. This contains
a bunch of things that have accumulated while 3.0 was in freeze.
Highlights are:
* SLOF firmware update
* A number of floating point cleanups from Richard Henderson and
Yasmin Beatriz
* A new model for assigning irq numbers on spapr, this is an
important preliminary step towards implementing the POWER9
"XIVE" interrupt controller

For large buffers, write may not copy the full buffer. For example,
on Linux, write imposes a limit of 0x7ffff000. Note that this does
not fix >4G transfers but ~>2G files will transfer successfully.

This is mandated by the ohci specification. It tells at 6.4.4 on page 104
that for transfer descriptors that are retired with an error the done
queue interrupt counter is cleared as if the interrupt delay field of the
descriptions were zero.
Before this change, error conditions were handled similarly to the
successful condition which is especially troublesome for control transfers.
Some drivers (e.g., the AmigaOS-one) as well as the example code in the
spec, set the setup stage with an interrupt delay of seven (which means no
interrupt). This is fine under normal conditions, because one usually
doesn't want to be notified about the completion of this stage. However, if
an error occurs in this stage, these drivers will not get notified with the
current implementation. The fix addresses this by following the spec more
closely. Also, otherwise, the ability to set interrupt delay to seven would
be useless.
Note that Linux drivers that I looked at don't seem to be affected as they
set six as the interrupt delay presumably for the reason that they won't
get notified otherwise.

According to the ramfb_setup() function, the ramfb device needs fw_cfg
with DMA, so we should also only compile and link it into those targets
which support it, to avoid that the device shows up on systems where it
can not be used at all (e.g. s390x).
