Current implementation of the imx spi controller expects the burst
length to be multiple of 8, which is the most common use case.
In case the burst length is not what we expect, log it to give user
a chance to notice it, and round it up to be multiple of 8.

When a write to ECSPI_CONREG register to disable the SPI controller,
imx_spi_soft_reset() is called to reset the controller, but chip
select lines should have been disabled, otherwise the state machine
of any devices (e.g.: SPI flashes) connected to the SPI master is
stuck to its last state and responds incorrectly to any follow-up
commands.

is going to reset its state anyway, so there's no need to actively
signal an irq line change during the reset hook.

When the frontend device has no space for a read the fd is removed
from polling to allow time for the guest to read and clear the buffer.
Without the call to qemu_chr_fe_accept_input(), the poll will not be
broken out of when the guest has cleared the buffer causing significant
IO delays that get worse with smaller buffers.

uint32_t flags) "dev: %p offset: %"PRIu32" \
size: %"PRIu32" flags: 0x%"PRIx32
generates:
printf("%d@%d vhost_vdpa_set_config dev: %p offset: %u size: %u \
flags: 0x%u\n", pid(), gettimeofday_ns(), dev, offset, \
size, flags)
for the "flags" parameter, we can see a "0x%u" rather than a "0x%x"
because the first macro was "PRIu32" (for offset).
In the loop, macro becomes "PRIu32PRIu32PRIx32", and c_macro_to_format()
returns always macro[3] ('u' in this case). This patch resets macro after
the format has been decoded.

Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

by noting support will target the current release, and the previous
release for a period of two years or until its EOL. This rule can also
apply to the other UNIX based distros, leaving only Windows needing a
different set of rules.
This also clarifies that Debian LTS is out of scope, because the LTS
support is provided by a separate group from the main Debian maintainer
team.

The -enable-fips option was added a long time ago to prevent the use of
single DES when VNC when FIPS mode is enabled. It should never have been
added, because apps are supposed to unconditionally honour FIPS mode
based on the '/proc/sys/crypto/fips_enabled' file contents.
In addition there is more to achieving FIPS compliance than merely
blocking use of certain algorithms. Those algorithms which are used
need to perform self-tests at runtime.
QEMU's built-in cryptography provider has no support for self-tests,
and neither does the nettle library.
If QEMU is required to be used in a FIPS enabled host, then it must be
built with the libgcrypt library enabled, which will unconditionally
enforce FIPS compliance in any algorithm usage.
Thus there is no need to keep either the -enable-fips option in QEMU, or
QEMU's internal FIPS checking methods.

If you set the loaded property to true when it was already true, the
state is overwritten without freeing the old state first. Change the
set_loaded callback so that it always frees the old state (which is a
no-op if nothing was loaded) and only then load if requestsd.

qcrypto_secret_prop_set_loaded() forgets to reset secret->rawdata after
unloading a secret, which will lead to a double free at some point.
Because there is no use case for unloading an already loaded secret
(apart from deleting the whole secret object) and we know that nobody
could use this because it would lead to crashes, let's just forbid the
operation instead of fixing the unloading.
Eventually, we'll want to get rid of 'loaded' in the external interface,
but for the meantime this is more consistent with rng, which has a
similar property 'opened' that also can't be reset to false after it
became true.

Instead of duplicating the code for user creatable objects in secret and

base class is abstract, it won't become user creatable itself.

Now that the watchdog device uses its Clock input rather than being
passed the value of system_clock_scale at creation time, we can
remove the hack where we reset the STELLARIS_SYS at board creation
time to force it to set system_clock_scale. Instead it will be reset
at the usual point in startup and will inform the watchdog of the
clock frequency at that point.

Create and connect the Clock input for the watchdog device on the
Stellaris boards. Because the Stellaris boards model the ability to
change the clock rate by programming PLL registers, we have to create
an output Clock on the ssys_state device and wire it up to the
watchdog.
Note that the old comment on ssys_calculate_system_clock() got the
units wrong -- system_clock_scale is in nanoseconds, not
milliseconds. Improve the commentary to clarify how we are
calculating the period.

Convert the SSYS code in the Stellaris boards (which encapsulates the
system registers) to a proper QOM device. This will provide us with
somewhere to put the output Clock whose frequency depends on the
setting of the PLL configuration registers.
This is a migration compatibility break for lm3s811evb, lm3s6965evb.
We use 3-phase reset here because the Clock will need to propagate
its value in the hold phase.
For the moment we reset the device during the board creation so that
the system_clock_scale global gets set; this will be removed in a
subsequent commit.
