f0e4588fd4 hw/i2c/pmbus_device: Fix modifying QOM class internals from instance
QOM object instance should not modify its class state (because
all other objects instanciated from this class get affected).

Instead of modifying the PMBusDeviceClass 'device_num_pages' field
the first time a instance is initialized (in pmbus_pages_alloc),
introduce a new pmbus_pages_num() helper which returns the page
number from the class without modifying the class state.

The code logic become slighly simplified.

51141cab3b hw/char/pl011: Display register name in trace events
To avoid knowing the register addresses by heart,
display their name along in the trace events.

Since the MMIO region is 4K wide (0x1000 bytes),
displaying the address with 3 digits is enough,
so reduce the address format.

b91b0fc163 accel: Remove HAX accelerator
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort
HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark
HAXM in QEMU as deprecated"), released in v8.0.0.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:

  Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.

The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:

  HAXM v7.8.0 is our last release and we will not accept
  pull requests or respond to issues after this.

It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help.  It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

e73b8bb8a3 hw/arm: Set number of MPU regions correctly for an505, an521, an524
The IoTKit, SSE200 and SSE300 all default to 8 MPU regions.  The
MPS2/MPS3 FPGA images don't override these except in the case of
AN547, which uses 16 MPU regions.

Define properties on the ARMSSE object for the MPU regions (using the
same names as the documented RTL configuration settings, and
following the pattern we already have for this device of using
all-caps names as the RTL does), and set them in the board code.

We don't actually need to override the default except on AN547,
but it's simpler code to have the board code set them always
rather than tracking which board subtypes want to set them to
a non-default value separately from what that value is.

Tho overall effect is that for mps2-an505, mps2-an521 and mps3-an524
we now correctly use 8 MPU regions, while mps3-an547 stays at its
current 16 regions.

It's possible some guest code wrongly depended on the previous
incorrectly modeled number of memory regions. (Such guest code
should ideally check the number of regions via the MPU_TYPE
register.) The old behaviour can be obtained with additional
-global arguments to QEMU:

For mps2-an521 and mps2-an524:
 -global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16 -global sse-200.CPU1_MPU_NS=16 -global sse-200.CPU1_MPU_S=16

For mps2-an505:
 -global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16

NB that the way the implementation allows this use of -global
is slightly fragile: if the board code explicitly sets the
properties on the sse-200 object, this overrides the -global
command line option. So we rely on:
 - the boards that need fixing all happen to use the SSE defaults
 - we can write the board code to only set the property if it
   is different from the default, rather than having all boards
   explicitly set the property
 - the board that does need to use a non-default value happens
   to need to set it to the same value (16) we previously used
This works, but there are some kinds of refactoring of the
mps2-tz.c code that would break the support for -global here.

cb0929bb13 hw/arm/armv7m: Add mpu-ns-regions and mpu-s-regions properties
M-profile CPUs generally allow configuration of the number of MPU
regions that they have.  We don't currently model this, so our
implementations of some of the board models provide CPUs with the
wrong number of regions.  RTOSes like Zephyr that hardcode the
expected number of regions may therefore not run on the model if they
are set up to run on real hardware.

Add properties mpu-ns-regions and mpu-s-regions to the ARMV7M object,
matching the ability of hardware to configure the number of Secure
and NonSecure regions separately.  Our actual CPU implementation
doesn't currently support that, and it happens that none of the MPS
boards we model set the number of regions differently for Secure vs
NonSecure, so we provide an interface to the boards and SoCs that
won't need to change if we ever do add that functionality in future,
but make it an error to configure the two properties to different
values.

(The property name on the CPU is the somewhat misnamed-for-M-profile
"pmsav7-dregion", so we don't follow that naming convention for
the properties here. The TRM doesn't say what the CPU configuration
variable names are, so we pick something, and follow the lowercase
convention we already have for properties here.)

b8f7959f28 target/arm: Do all "ARM_FEATURE_X implies Y" checks in post_init
Where architecturally one ARM_FEATURE_X flag implies another
ARM_FEATURE_Y, we allow the CPU init function to only set X, and then
set Y for it.  Currently we do this in two places -- we set a few
flags in arm_cpu_post_init() because we need them to decide which
properties to create on the CPU object, and then we do the rest in
arm_cpu_realizefn().  However, this is fragile, because it's easy to
add a new property and not notice that this means that an X-implies-Y
check now has to move from realize to post-init.

As a specific example, the pmsav7-dregion property is conditional
on ARM_FEATURE_PMSA && ARM_FEATURE_V7, which means it won't appear
on the Cortex-M33 and -M55, because they set ARM_FEATURE_V8 and
rely on V8-implies-V7, which doesn't happen until the realizefn.

Move all of these X-implies-Y checks into a new function, which
we call at the top of arm_cpu_post_init(), so the feature bits
are available at that point.

This does now give us the reverse issue, that if there's a feature
bit which is enabled or disabled by the setting of a property then
then X-implies-Y features that are dependent on that property need to
be in realize, not in this new function.  But the only one of those
is the "EL3 implies VBAR" which is already in the right place, so
putting things this way round seems better to me.

5ec008a2bd rtc: Use time_t for passing and returning time offsets
The functions qemu_get_timedate() and qemu_timedate_diff() take
and return a time offset as an integer. Coverity points out that
means that when an RTC device implementation holds an offset
as a time_t, as the m48t59 does, the time_t will get truncated.
(CID 1507157, 1517772).

The functions work with time_t internally, so make them use that type
in their APIs.

Note that this won't help any Y2038 issues where either the device
model itself is keeping the offset in a 32-bit integer, or where the
hardware under emulation has Y2038 or other rollover problems.  If we
missed any cases of the former then hopefully Coverity will warn us
about them since after this patch we'd be truncating a time_t in
assignments from qemu_timedate_diff().)

12517bc978 Add i.MX7 SRC device implementation
The SRC device is normally used to start the secondary CPU.

When running Linux directly, QEMU is emulating a PSCI interface that UBOOT
is installing at boot time and therefore the fact that the SRC device is
unimplemented is hidden as Qemu respond directly to PSCI requets without
using the SRC device.

But if you try to run a more bare metal application (maybe uboot itself),
then it is not possible to start the secondary CPU as the SRC is an
unimplemented device.

This patch adds the ability to start the secondary CPU through the SRC
device so that you can use this feature in bare metal applications.

6f97cfd8e0 Remove i.MX7 IOMUX GPR device from i.MX6UL
i.MX7 IOMUX GPR device is not equivalent to i.MX6UL IOMUXC GPR device.
In particular, register 22 is not present on i.MX6UL and this is actualy
The only register that is really emulated in the i.MX7 IOMUX GPR device.

Note: The i.MX6UL code is actually also implementing the IOMUX GPR device
as an unimplemented device at the same bus adress and the 2 instantiations
were actualy colliding. So we go back to the unimplemented device for now.

9e771a2fc6 target/arm: properly document FEAT_CRC32
This is a mandatory feature for Armv8.1 architectures but we don't
state the feature clearly in our emulation list. Also include
FEAT_CRC32 comment in aarch64_max_tcg_initfn for ease of grepping.

df9a391757 target/arm: Implement FEAT_HPDS2 as a no-op
This feature allows the operating system to set TCR_ELx.HWU*
to allow the implementation to use the PBHA bits from the
block and page descriptors for for IMPLEMENTATION DEFINED
purposes.  Since QEMU has no need to use these bits, we may
simply ignore them.
