0bf355e6ca edu: fix DMA range upper bound check
The edu_check_range function checks that start <= end1 < end2, where
end1 is the upper bound (exclusive) of the guest-supplied DMA range and
end2 is the upper bound (exclusive) of the device's allowed DMA range.
When the guest tries to transfer exactly DMA_SIZE (4096) bytes, end1
will be equal to end2, so the check fails and QEMU aborts with this
puzzling error message (newlines added for formatting):

  qemu: hardware error: EDU: DMA range
    0x0000000000040000-0x0000000000040fff out of bounds
   (0x0000000000040000-0x0000000000040fff)!

By checking end1 <= end2 instead, guests will be allowed to transfer
exactly 4096 bytes. It is not necessary to explicitly check for
start <= end1 because the previous two checks (within(addr, start, end2)
and end1 > addr) imply start < end1.

896dd6ff7b hw/misc/mps2-scc: Free MPS2SCC::oscclk[] array on finalize()
Commit 0be6bfac62 ("qdev: Implement variable length array properties")
added the DEFINE_PROP_ARRAY() macro with the following comment:

  * It is the responsibility of the device deinit code to free the
  * @_arrayfield memory.

Commit 4fb013afcc added:

  DEFINE_PROP_ARRAY("oscclk", MPS2SCC, num_oscclk, oscclk_reset,
                    qdev_prop_uint32, uint32_t),

but forgot to free the 'oscclk_reset' array. Do it in the
instance_finalize() handler.

921923583f hw/misc: Introduce AMD/Xilix Versal TRNG device
This adds a non-cryptographic grade implementation of the
model for the True Random Number Generator (TRNG) component
in AMD/Xilinx Versal device family.

This implements all 3 modes defined by the actual hardware
specs, all of which selectable by guest software at will
at anytime:
1) PRNG mode, in which the generated sequence is required to
   be reproducible after reseeded by the same 384-bit value
   as supplied by guest software.
2) Test mode, in which the generated sequence is required to
   be reproducible ater reseeded by the same 128-bit test
   seed supplied by guest software.
3) TRNG mode, in which non-reproducible sequence is generated
   based on periodic reseed by a suitable entropy source.

This model is only intended for non-real world testing of
guest software, where cryptographically strong PRNG or TRNG
is not needed.

This model supports versions 1 & 2 of the device, with
default to be version 2; the 'hw-version' uint32 property
can be set to 0x0100 to override the default.

Other implemented properties:
- 'forced-prng', uint64
  When set to non-zero, mode 3's entropy source is implemented
  as a deterministic sequence based on the given value and other
  deterministic parameters.
  This option allows the emulation to test guest software using
  mode 3 and to reproduce data-dependent defects.

- 'fips-fault-events', uint32, bit-mask
  bit 3: Triggers the SP800-90B entropy health test fault irq
  bit 1: Triggers the FIPS 140-2 continuous test fault irq

c8a7fc5179 migration: simplify blockers
Modify migrate_add_blocker and migrate_del_blocker to take an Error **
reason.  This allows migration to own the Error object, so that if
an error occurs in migrate_add_blocker, migration code can free the Error
and clear the client handle, simplifying client code.  It also simplifies
the migrate_del_blocker call site.

In addition, this is a pre-requisite for a proposed future patch that would
add a mode argument to migration requests to support live update, and
maintain a list of blockers for each mode.  A blocker may apply to a single
mode or to multiple modes, and passing Error** will allow one Error object
to be registered for multiple modes.

No functional change.

53af33a5b4 hw/misc/mips_itu: Make MIPSITUState target agnostic
When prototyping a heterogenous machine including the ITU,
we get:

  include/hw/misc/mips_itu.h:76:5: error: unknown type name 'MIPSCPU'
      MIPSCPU *cpu0;
      ^

MIPSCPU is declared in the target specific "cpu.h" header,
but we don't want to include it, because "cpu.h" is target
specific and its inclusion taints all files including
"mips_itu.h", which become target specific too. We can
however use the 'ArchCPU *' type in the public header.
By keeping the TYPE_MIPS_CPU QOM type check in the link
property declaration, QOM core code will still check the
property is a correct MIPS CPU.

TYPE_MIPS_ITU is still built per-(MIPS)target, but its header
can now be included by other targets.

b4d3a83b89 mac_via: extend timer calibration hack to work with A/UX
The A/UX timer calibration loop runs continuously until 2 consecutive iterations
differ by at least 0x492 timer ticks. Modern hosts execute the timer calibration
loop so fast that this situation never occurs causing a hang on boot.

Use a similar method to Shoebill which is to randomly add 0x500 to the T2
counter value during calibration to enable it to eventually succeed.

c698b0c8ed mac_via: always clear ADB interrupt when switching to A/UX mode
When the NetBSD kernel initialises it can leave the ADB interrupt asserted
depending upon where in the ADB poll cycle the MacOS ADB interrupt handler
is when the NetBSD kernel disables interrupts.

The NetBSD ADB driver uses the ADB interrupt state to determine if the ADB
is busy and refuses to send ADB commands unless it is clear. To ensure that
this doesn't happen, always clear the ADB interrupt when switching to A/UX
mode to ensure that the bus enumeration always occurs.

NetBSD assumes it can send its first ADB command after sending the ADB_BUSRESET
command in ADB_STATE_NEW without changing the state back to ADB_STATE_IDLE
first as detailed in the ADB protocol.

Add a workaround to detect this condition at the start of ADB enumeration
and send the next command written to SR after a ADB_BUSRESET onto the bus
regardless, even if we don't detect a state transition to ADB_STATE_NEW.

366d27796c mac_via: work around underflow in TimeDBRA timing loop in SETUPTIMEK
The MacOS toolbox ROM calculates the number of branches that can be executed
per millisecond as part of its timer calibration. Since modern hosts are
considerably quicker than original hardware, the negative counter reaches zero
before the calibration completes leading to division by zero later in
CALCULATESLOD.

Instead of trying to fudge the timing loop (which won't work for TimeDBRA/TimeSCCDB
anyhow), use the pattern of access to the VIA1 registers to detect when SETUPTIMEK
has finished executing and write some well-known good timer values to TimeDBRA
and TimeSCCDB taken from real hardware with a suitable scaling factor.

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.

532009054b mac_via: fix rtc command decoding for the PRAM seconds registers
Analysis of the MacOS toolbox ROM code shows that on startup it attempts 2
separate reads of the seconds registers with commands 0x9d...0x91 followed by
0x8d..0x81 without resetting the command to its initial value. The PRAM seconds
value is only accepted when the values of the 2 separate reads match.

From this we conclude that bit 4 of the rtc command is not decoded or we don't
care about its value when reading the PRAM seconds registers. Implement this
decoding change so that both reads return successfully which allows the MacOS
toolbox ROM to correctly set the date/time.

c8f48b120b aspeed/hace: Initialize g_autofree pointer
As mentioned in docs/devel/style.rst "Automatic memory deallocation":

* Variables declared with g_auto* MUST always be initialized,
  otherwise the cleanup function will use uninitialized stack memory

This avoids QEMU to coredump when running the "hash test" command
under Zephyr.

most of the clock generation, division, distribution, synchronization
and gating.

This commit adds support for the Clock Control Unit which emulates
a simple read/write register interface.
