The Xen HVM unplug protocol [1] specifies a mechanism to allow guests to
request unplug of 'aux' disks (which is stated to mean all IDE disks,
except the primary master). This patch adds support for that unplug request.
NOTE: The semantics of what happens if unplug of all disks and 'aux' disks
is simultaneously requests is not clear. The patch makes that
assumption that an 'all' request overrides an 'aux' request.

The current code is poorly structured and potentially leads to multiple
config space reads when one is sufficient. Also the UNPLUG_ALL_IDE_DISKS
flag is mis-named since it also results in SCSI disks being unplugged.
This patch renames the flag and re-structures the code to be more
efficient, and readable.

When the guest attempts to start an MII register
access via the MCTL register, clear the START bit,
so that when the guest reads it back the register
transaction will be signalled as having completed.
This avoids the guest spinning as it polls the
START bit waiting for it to clear (which it
previously never would).
The MII registers themselves still aren't implemented,
but at least we can avoid guests spending quite so much
time busy waiting.

Many NVIC operations access the CPU state, so store a pointer in
struct nvic_state rather than fetching it via qemu_get_cpu() every
time we need it.
As with the arm_gicv3_common code, we currently just call
qemu_get_cpu() in the NVIC's realize method, but in future we might
want to use a QOM property to pass the CPU to the NVIC.
This imposes an ordering requirement that the CPU is
realized before the NVIC, but that is always true since
both are dealt with in armv7m_init().

For configurations of the pflash_cfi01 device which set it up with a
device-width not equal to the width (ie where we are emulating
multiple narrow flash devices wired up in parallel), we were giving
incorrect values in the CFI data table:
(1) the sector length entry should specify the sector length for a
single device, not the length for the overall collection of
devices
(2) the number of blocks per device must not be divided by the
number of devices because the resulting device size would not
match the overall size
(3) this then means that the overall write block size must be
modified depending on the number of devices because the entry is
per device and when the guest writes into the flash it
calculates the write size by using the CFI entry (write size
per device) multiplied by the number of chips.
(It would alternatively be possible to modify the write
block size in the CFI table (currently hardcoded at 2048) and
leave the overall write block size alone.)
This commit corrects these bugs, and adds a hw-compat property
to retain the old behaviour on 2.8 and earlier versions. (The
only board we have which uses this sort of flash config and
has machine versioning is the "virt" board -- the PC uses a
single flash device and so behaviour is unaffected whether
using old-multiple-chip-handling or not.)
Here is a configuration example from the vexpress board:
VEXPRESS_FLASH_SIZE = 64M
VEXPRESS_FLASH_SECT_SIZE 256K
num-blocks = VEXPRESS_FLASH_SIZE / VEXPRESS_FLASH_SECT_SIZE = 256
sector-length = 256K
width = 4
device-width = 2
The code will fill the CFI entry with the following entries:
num-blocks = 256
sector-length = 128K
writeblock_size = 2048
This results in two chips, each with 256 * 128K = 32M device size and
a write block size of 2048.
A sector erase will be sent to both chips, thus 256K must be erased.
When the guest sends a block write command, it will write 4096 bytes
data at once (2048 per device).

The current code tries to copy `read_count' bytes starting at offset
`offset' from a `read_count`-sized iovec. This causes v9fs_pack() to
fail with ENOBUFS.
Since the PDU iovec is already partially filled with `offset' bytes,
let's skip them when creating `qiov_full' and have v9fs_pack() to
copy the whole of it. Moreover, this is consistent with the other
places where v9fs_init_qiov_from_pdu() is called.
This fixes commit "bcb8998fac16 9pfs: call v9fs_init_qiov_from_pdu

The server can handle MAX_REQ - 1 PDUs at a time and the virtio-9p

This has been there since the beginning (commit 9f10751365 "virtio-9p:

run in the guest to show up.
We actually allocate MAX_REQ PDUs and I see no reason not to link them

just in the size of one buffer; combine the two using a _TEST

I think this is safe as long as everywhere which currently

One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?

Sometimes it is useful to have just a machine with CPU and RAM, without
any further hardware in it, e.g. if you just want to do some instruction
debugging for TCG with a remote GDB attached to QEMU, or run some embedded
code with the "-semihosting" QEMU parameter. qemu-system-m68k already
features a "dummy" machine, and xtensa a "sim" machine for exactly this
purpose.
All target architectures have nowadays also a "none" machine, which would
be a perfect match for this, too - but it currently does not allow to add
CPU and RAM yet. Thus let's add these possibilities in a generic way to the
"none" machine, too, so that we hopefully do not need additional "dummy"
machines in the future anymore (and maybe can also get rid of the already
existing "dummy"/"sim" machines one day).
Note that the default behaviour of the "none" machine is not changed, i.e.
no CPU and no RAM is instantiated by default. You have explicitely got to
specify the CPU model with "-cpu" and the amount of RAM with "-m" to get
these new features.

Add a board level property to the virt board which will
enable EL2 on the CPU if the user asks for it. The
default is not to provide EL2. If EL2 is enabled then
we will use SMC as our PSCI conduit, and report the
virtualization support in the GICv3 device tree node
and the ACPI tables.

Enable the ARM_FEATURE_EL2 bit on Cortex-A52 and
Cortex-A57, since this is all now sufficiently implemented
to work with the GICv3. We provide the usual CPU property
to disable it for backwards compatibility with the older
virt boards.
In this commit, we disable the EL2 feature on the
virt and ZynpMP boards, so there is no overall effect.
Another commit will expose a board-level property to
allow the user to enable EL2.
