The Jazz use the RC4030 Asic to provide an EISA bus and DMA/IRQ.
The framebuffer display is managed by a G364, the network card is
a Sonic DP83932. A QLogic ESP216 provides a SCSI bus.
None, for the both machine variants (PICA-61 and Magnum 4000),
the DP83932 chipset is soldered on the board, and is MMIO-mapped
(selected via Chip Select). Therefore we have to enforce the
'select' Kconfig rule (we can not use the 'imply' rule helpful
when devices are connected on a bus).

[Straightforwardly updated for "MAINTAINERS: Make section "QOM" cover
qdev as well"]
Previously there was a single instance of the timer used by
monitor triggered announces, that's OK, but when combined with the
previous change that lets you have announces for subsets of interfaces
it's a bit restrictive if you want to do different things to different
interfaces.
Add an 'id' field to the announce, and maintain a list of the
timers based on id.
This allows you to for example:
a) Start an announce going on interface eth0 for a long time
b) Start an announce going on interface eth1 for a long time
c) Kill the announce on eth0 while leaving eth1 going.

During a sector erase (but not a chip erase), the embeded erase program
can be suspended. Once suspended, the sectors not selected for erasure
may be read and programmed. Autoselect mode is allowed during erase
suspend mode. Presumably, CFI queries are similarly allowed so this
commit allows them as well.
Since guest firmware can use status bits DQ7, DQ6, DQ3, and DQ2 to
determine the current state of sector erasure, these bits are properly
implemented.

When the flash device is performing a chip erase, all commands are
ignored. When it is performing a sector erase, only the erase suspend
command is valid, which is currently not supported.
In particular, the reset command should not cause the device to reset to
read array mode while programming is on going.

Some flash chips support sectors of different sizes. For example, the
AMD AM29LV160DT has 31 64 kB sectors, one 32 kB sector, two 8 kB
sectors, and a 16 kB sector, in that order. The AM29LV160DB has those in
the reverse order.
The `num-blocks` and `sector-length` properties work exactly as they did
before: a flash device with uniform sector lengths. To get non-uniform
sector lengths for up to four regions, the following properties may be
set
- region 0. `num-blocks0` and `sector-length0`;
- region 1. `num-blocks1` and `sector-length1`;
- region 2. `num-blocks2` and `sector-length2`; and
- region 3. `num-blocks3` and `sector-length3`.
If the uniform and nonuniform properties are set, then both must specify
a flash device with the same total size. It would be better to disallow
both being set, or make `num-blocks0` and `sector-length0` alias
`num-blocks` and `sector-length`, but that would make testing currently
impossible.

When the software modifies the XIVE internal structures, ESB, EAS,
END, NVT, it also must update the caches of the different XIVE
sub-engines. HW offers a set of common interface for such purpose.
The CWATCH_SPEC register defines the block/index of the target and a
set of flags to perform a full update and to watch for update
conflicts.
The cache watch CWATCH_DATAX registers are then loaded with the target
data with a first read on CWATCH_DATA0. Writing back is done in the
opposit order, CWATCH_DATA0 triggering the update.
The SCRUB_TRIG registers are used to flush the cache in RAM, and to
possibly invalidate it. Cache disablement is also an option but as we
do not model the cache, these registers are no-ops
Today, the modeling of these registers is incorrect but it did not
impact the set up of a baremetal system. However, running KVM requires
a rework.

When an interrupt needs to be delivered, the XIVE interrupt controller
presenter scans the CAM lines of the thread interrupt contexts of the
HW threads of the chip to find a matching vCPU. The interrupt context
is composed of 4 different sets of registers: Physical, HV, OS and
User.
The encoding of the Physical CAM line depends on the mode in which the
interrupt controller is operating: CAM mode or block group mode.
Block group mode being the default configuration today on POWER9 and
the only one available on the next POWER10 generation, enforce this
encoding in the Physical CAM line :
chip << 19 | 0000000 0 0001 thread (7Bit)
It fits the overall encoding of the NVT ids and simplifies the matching
algorithm in the presenter.

Today, the interrupt device is fully initialized at reset when the CAS
negotiation process has completed. Depending on the KVM capabilities,
the SpaprXive memory regions (ESB, TIMA) are initialized with a host
MMIO backend or a QEMU emulated backend. This results in a complex
initialization sequence partially done at realize and later at reset,
and some memory region leaks.
To simplify this sequence and to remove of the late initialization of
the emulated device which is required to be done only once, we
introduce new memory regions specific for KVM. These regions are
mapped as overlaps on top of the emulated device to make use of the
host MMIOs. Also provide proper cleanups of these regions when the
XIVE KVM device is destroyed to fix the leaks.

'as' is the IOMMU address space, which indeed has a listener registered
to by vfio_connect_container() when the VFIO device is realized. This
listener is supposed to be unregistered by vfio_disconnect_container()
when the VFIO device is finalized. Unfortunately, the VFIO device hasn't
reached finalize yet at the time the PHB unrealize function is called,
and address_space_destroy() gets called with the VFIO listener still
being registered.
All regions have just been unmapped from the address space. Listeners
aren't needed anymore at this point. Remove them before destroying the
address space.
The VFIO code will try to remove them _again_ at device finalize,
but it is okay since memory_listener_unregister() is idempotent.
