10717c26db spapr/vof: Install rom and nvram binaries
This installs VOF-related binaries (the firmware and the preformatted
NVRAM) as those were left out when the VOF was submitted initially.

205eb5a89e target/ppc: Change VSX instructions behavior to fill with zeros
ISA v3.1 changed some VSX instructions behavior by changing what the
other words/doubleword in the result should contain when the result is
only one word/doubleword. e.g. xsmaxdp operates on doubleword 0 and
saves the result also in doubleword 0.
Before, the second doubleword result was undefined according to the
ISA, but now it's stated that it should be zeroed.

Even tough the result was undefined before, hardware implementing these
instructions already filled these fields with 0s. Changing every ISA
version in QEMU to this behavior makes the results match what happens
in hardware.

10895ab6f7 target/ppc: books: Remove excp_model argument from ppc_excp_apply_ail
We don't really need to check for exception model while applying
AIL. We can check the lpcr_mask for the presence of
LPCR_AIL/LPCR_HAIL.

This removes one more instance of passing the exception model ID
around.

fce9fbafe9 target/ppc: Assert if MSR bits differ from msr_mask during exceptions
We currently abort QEMU during the dispatch of an interrupt if we try
to set MSR_HV without having MSR_HVB in the msr_mask. I think we
should verify this for all MSR bits. There is no reason to ever have a
MSR bit set if the corresponding bit is not set in that CPU's
msr_mask.

Note that this is not about the emulated code setting reserved
bits. We clear the new_msr when starting to dispatch an exception, so
if we end up with bits not present in the msr_mask that is a QEMU
programming error.

I kept the HSRR verification for BookS because it is the only CPU
family that has HSRRs.

005b69fdcc target/ppc: Remove PowerPC 601 CPUs
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.

180952cedc target/ppc: Introduce powerpc_excp_booke
Introduce a new powerpc_excp function specific for BookE CPUs. This
commit copies powerpc_excp_legacy verbatim so the next one has a clean

4fd1ebb105 hw/sensor: Add lsm303dlhc magnetometer device
This commit adds emulation of the magnetometer on the LSM303DLHC.
It allows the magnetometer's X, Y and Z outputs to be set via the
mag-x, mag-y and mag-z properties, as well as the 12-bit
temperature output via the temperature property. Sensor can be
enabled with 'CONFIG_LSM303DLHC_MAG=y'.

d7d359c4ac hw/intc/arm_gicv3_its: Split error checks
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.

3330241407 hw/intc/arm_gicv3_its: Don't allow intid 1023 in MAPI/MAPTI
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.

84d43d2e82 hw/intc/arm_gicv3_its: In MAPC with V=0, don't check rdbase field
In the MAPC command, if V=0 this is a request to delete a collection
table entry and the rdbase field of the command packet will not be
used.  In particular, the specification says that the "UNPREDICTABLE
if rdbase is not valid" only applies for V=1.

We were doing a check-and-log-guest-error on rdbase regardless of
whether the V bit was set, and also (harmlessly but confusingly)
storing the contents of the rdbase field into the updated collection
table entry.  Update the code so that if V=0 we don't check or use
the rdbase field value.

da4680ce3a hw/intc/arm_gicv3_its: Drop TableDesc and CmdQDesc valid fields
Currently we track in the TableDesc and CmdQDesc structs the state of
the GITS_BASER<n> and GITS_CBASER Valid bits.  However we aren't very
consistent abut checking the valid field: we test it in update_cte()
and update_dte(), but not anywhere else we look things up in tables.

The GIC specification says that it is UNPREDICTABLE if a guest fails
to set any of these Valid bits before enabling the ITS via
GITS_CTLR.Enabled.  So we can choose to handle Valid == 0 as
equivalent to a zero-length table.  This is in fact how we're already
catching this case in most of the table-access paths: when Valid is 0
we leave the num_entries fields in TableDesc or CmdQDesc set to zero,
and then the out-of-bounds check "index >= num_entries" that we have
to do anyway before doing any of these table lookups will always be
true, catching the no-valid-table case without any extra code.

So we can remove the checks on the valid field from update_cte()
and update_dte(): since these happen after the bounds check there
was never any case when the test could fail. That means the valid
fields would be entirely unused, so just remove them.

7eb54267f2 hw/intc/arm_gicv3_its: Make update_ite() use ITEntry
Make the update_ite() struct use the new ITEntry struct, so that
callers don't need to assemble the in-memory ITE data themselves, and
only get_ite() and update_ite() need to care about that in-memory
layout.  We can then drop the no-longer-used IteEntry struct
definition.

244194fe24 hw/intc/arm_gicv3_its: Pass ITE values back from get_ite() via a struct
In get_ite() we currently return the caller some of the fields of an
Interrupt Table Entry via a set of pointer arguments, and validate
some of them internally (interrupt type and valid bit) to return a
simple true/false 'valid' indication. Define a new ITEntry struct
which has all the fields that the in-memory ITE has, and bring the
get_ite() function in to line with get_dte() and get_cte().

This paves the way for handling virtual interrupts, which will want
a different subset of the fields in the ITE. Handling them under
the old "lots of pointer arguments" scheme would have meant a
confusingly large set of arguments for this function.

The new struct ITEntry is obviously confusably similar to the
existing IteEntry struct, whose fields are the raw 12 bytes
of the in-memory ITE. In the next commit we will make update_ite()
use ITEntry instead of IteEntry, which will allow us to delete
the IteEntry struct and remove the confusion.
