The read_tcnt() function calculates the TCNT register values for the
two channels of the timer module; it sets these up in the local
tcnt[] array, and eventually returns either one or both of them,
depending on whether the access is 8 or 16 bits. However, not all of
the code paths through this function set both elements of this array:
if the guest has programmed the TCCR.CSS register fields to values
which are either documented as not to be used or which QEMU does not
implement, then the function will return uninitialized data. (This
was spotted by Coverity.)
Add the missing CSS cases to this code, so that we return a
consistent value instead of uninitialized data, and so the code
structure indicates what's happening.

Keyboard-Controller-Style devices for IPMI purposes are exposed via LPC
IO cycles from the BMC to the host.
Expose support on the BMC side by implementing the usual MMIO
behaviours, and expose the ability to inspect the KCS registers in
"host" style by accessing QOM properties associated with each register.
The model caters to the IRQ style of both the AST2600 and the earlier
SoCs (AST2400 and AST2500). The AST2600 allocates an IRQ for each LPC
sub-device, while there is a single IRQ shared across all subdevices on
the AST2400 and AST2500.

The ast2600 machines do not have PSCI firmware, so this property should
have never been set. Removing this node fixes SMP booting Linux kernels
that have PSCI enabled, as Linux fails to find PSCI in the device tree
and falls back to the soc-specific method for enabling secondary CPUs.
The comment is out of date as Qemu has supported -kernel booting since
9bb6d14081 ("aspeed: Add boot stub for smp booting"), in v5.1.

The "get-vm-images" target defined in tests/Makefile.include is a
prerequisite for "check-acceptance", so that those files get
downloaded before the Avocado job even starts.
It looks like on c401c058a1 a TARGETS variable was introduced with a
different content than it was previously coming from the main
Makefile. From that point on, the "get-vm-images" succeed without
doing anything because there was no matching architecture to download.
This restores the download of images (that match targets to be built)
before the job starts, eliminating downloads and their associated
failures during the tests.

If namespace inventory is changed due to some reasons (e.g., namespace
attachment/detachment), controller can send out event notifier to the
host to manage namespaces.
This patch sends out the AEN to the host after either attach or detach
namespaces from controllers. To support clear of the event from the
controller, this patch also implemented Get Log Page command for Changed
Namespace List log type. To return namespace id list through the
command, when namespace inventory is updated, id is added to the
per-controller list (changed_ns_list).
To indicate the support of this async event, this patch set
OAES(Optional Asynchronous Events Supported) in Identify Controller data
structure.

This patch supports Namespace Attachment command for the pre-defined
nvme-ns device nodes. Of course, attach/detach namespace should only be
supported in case 'subsys' is given. This is because if we detach a
namespace from a controller, somebody needs to manage the detached, but
allocated namespace in the NVMe subsystem.
As command effect for the namespace attachment command is registered,
the host will be notified that namespace inventory is changed so that
host will rescan the namespace inventory after this command. For
example, kernel driver manages this command effect via passthru IOCTL.

From NVMe spec 1.4b "6.1.5. NSID and Namespace Relationships" defines
valid namespace types:
- Unallocated: Not exists in the NVMe subsystem
- Allocated: Exists in the NVMe subsystem
- Inactive: Not attached to the controller
- Active: Attached to the controller
This patch added support for allocated, but not attached namespace type:
!nvme_ns(n, nsid) && nvme_subsys_ns(n->subsys, nsid)
nvme_ns() returns attached namespace instance of the given controller
and nvme_subsys_ns() returns allocated namespace instance in the
subsystem.

Expand allocated namespace list (subsys->namespaces) to have 256 entries
which is a value lager than at least NVME_MAX_NAMESPACES which is for
attached namespace list in a controller.
Allocated namespace list should at least larger than attached namespace
list.
n->num_namespaces = NVME_MAX_NAMESPACES;
The above line will set the NN field by id->nn so that the subsystem
should also prepare at least this number of namespace list entries.

Given that now we have nvme-subsys device supported, we can manage
namespace allocated, but not attached: detached. This patch introduced
a parameter for nvme-ns device named 'detached'. This parameter
indicates whether the given namespace device is detached from
a entire NVMe subsystem('subsys' given case, shared namespace) or a
controller('bus' given case, private namespace).
- Allocated namespace
1) Shared ns in the subsystem 'subsys0':
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,subsys=subsys0,detached=true
2) Private ns for the controller 'nvme0' of the subsystem 'subsys0':
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true
3) (Invalid case) Controller 'nvme0' has no subsystem to manage ns:
-device nvme,serial=foo,id=nvme0
-device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true

The nvme_dma function doesn't just do DMA (QEMUSGList-based) memory transfers;
it also handles QEMUIOVector copies.
Introduce the NvmeTxDirection enum and rename to nvme_tx. Remove mapping
of PRPs/SGLs from nvme_tx and instead assert that they have been mapped
previously. This allows more fine-grained use in subsequent patches.
Add new (better named) helpers, nvme_{c2h,h2c}, that does both PRP/SGL
mapping and transfer.

ZASL (Zone Append Size Limit) is defined exactly like MDTS (Maximum Data
Transfer Size), that is, it is a value in units of the minimum memory
page size (CAP.MPSMIN) and is reported as a power of two.
The 'mdts' nvme device parameter is specified as in the spec, but the
'zoned.append_size_limit' parameter is specified in bytes. This is
suboptimal for a number of reasons:
1. It is just plain confusing wrt. the definition of mdts.
2. There is a lot of complexity involved in validating the value; it
must be a power of two, it should be larger than 4k, if it is zero
we set it internally to mdts, but still report it as zero.
3. While "hw/block/nvme: improve invalid zasl value reporting"
slightly improved the handling of the parameter, the validation is
still wrong; it does not depend on CC.MPS, it depends on
CAP.MPSMIN. And we are not even checking that it is actually less
than or equal to MDTS, which is kinda the *one* condition it must
satisfy.
Fix this by defining zasl exactly like mdts and checking the one thing
that it must satisfy (that it is less than or equal to mdts). Also,
change the default value from 128KiB to 0 (aka, whatever mdts is).
