deeb996935 hw/arm/v7m: Remove use of &first_cpu in machine_init()
When instanciating the machine model, the machine_init()
implementations usually create the CPUs, so have access
to its first CPU. Use that rather then the &first_cpu
global.

19266bec27 hw/arm/stellaris: Add 'armv7m' local variable
While the TYPE_ARMV7M object forward its NVIC interrupt lines,
it is somehow misleading to name it 'nvic'. Add the 'armv7m'
local variable for clarity, but also keep the 'nvic' variable
behaving like before when used for wiring IRQ lines.

a22acbb252 aspeed/wdt: Support software reset mode for AST2600
On the AST2400 and AST2500 platforms, the system can only be reset by enabling
the WDT (Watchdog Timer) and waiting for the WDT timeout. However, starting
from the AST2600 platform, the reset event can be triggered directly and
intentionally by software, without relying on the WDT timeout.

This mechanism, referred to as "software restart", is implemented in hardware.
When using the software restart mechanism, the WDT counter is not enabled.

To trigger a reset generation in software mode, write 0xAEEDF123 to register
0x24 and software mode reset only support SOC reset mode.

A new function, "aspeed_wdt_is_soc_reset_mode", is introduced to determine
whether the SoC reset mode is active.

f7ae9612fb test/functional: Update buildroot images to 2024.11
The main changes compared to upstream 2024.11 buildroot are

- bumped Linux to version 6.11.11 with a custom config
- changed U-Boot to OpenBMC branch for more support
- included extra target packages

See branch [1] for more details.

There is a slight output change when powering off the machine,
the console now contains :

    reboot: Power off not available: System halted

Adjust accordingly the expect string in
do_test_arm_aspeed_buildroot_poweroff().

8bc691bed8 hw/timer/aspeed: Add AST2700 Support
The timer controller include 8 sets of 32-bit decrement counters, based on
either PCLK or 1MHZ clock and the design of timer controller between AST2600
and AST2700 are almost the same.

TIMER0 – TIMER7 has their own individual control and interrupt status register.
In other words, users are able to set timer control in register TMC10 with
different TIMER base address and clear timer control and interrupt status in
register TMC14 with different TIMER base address.

Introduce new "aspeed_2700_timer_read" and "aspeed_2700_timer_write" callback
functions and a new ast2700 class to support AST2700.

The base address of TIMER0 to TIMER7 as following.
Base Address of Timer 0 = 0x12C1_0000
Base Address of Timer 1 = 0x12C1_0040
Base Address of Timer 2 = 0x12C1_0080
Base Address of Timer 3 = 0x12C1_00C0
Base Address of Timer 4 = 0x12C1_0100
Base Address of Timer 5 = 0x12C1_0140
Base Address of Timer 6 = 0x12C1_0180
Base Address of Timer 7 = 0x12C1_01C0

The register address space of each TIMER is "0x40" , and uses the following
formula to get the index and register of each TIMER.

timer_index = offset >> 6;
timer_offset = offset & 0x3f;

The TMC010 is a counter control set and interrupt status register. Write "1" to
TMC10[3:0] will set the specific bits to "1". Introduce a new
"aspeed_2700_timer_set_ctrl" function to handle this register behavior.

The TMC014 is a counter control clear and interrupt status register, to clear
the specific bits to "0", it should write "1" to  TMC14[3:0] on the same bit
position. Introduce a new "aspeed_2700_timer_clear_ctrl" function to handle
this register behavior. TMC014 does not support read operation.

ef2385bb37 hw/timer/aspeed: Refactor Timer Callbacks for SoC-Specific Implementations
The register set have a significant change in AST2700. The TMC00-TMC3C
are used for TIMER0 and TMC40-TMC7C are used for TIMER1. In additional,
TMC20-TMC3C and TMC60-TMC7C are reserved registers for TIMER0 and TIMER1,
respectively.

Besides, each TIMER has their own control and interrupt status register.
In other words, users are able to set control and interrupt status for TIMER0
in one register. Both aspeed_timer_read and aspeed_timer_write callback
functions are not compatible AST2700.

Introduce common read and write functions for ASPEED timers.
Modify the aspeed_timer_read and aspeed_timer_write functions to delegate to
SoC-specific callbacks first.
Update the AST2400, AST2500, AST2600 and AST1030 specific read and write
functions to call the common implementations for common register accesses.

This refactoring improves the organization of call delegation and prepares the
codebase for future SoC-specific specializations, such as the AST2700.

bf8a471a38 hw/arm/aspeed: Invert sdhci write protected pin for AST2600 EVB
The Write Protect pin of SDHCI model is default active low to match the SDHCI

property in ASPEED MACHINE State and set it true for AST2600 EVB

f2cb78bdbe rust: vmstate: implement VMState for scalar types
Scalar types are those that have their own VMStateInfo.  This poses
a problem in that references to VMStateInfo can only be included in
associated consts starting with Rust 1.83.0, when the const_refs_static
was stabilized.  Removing the requirement is done by placing a limited
list of VMStateInfos in an enum, and going from enum to &VMStateInfo
only when building the VMStateField.

The same thing cannot be done with VMS_STRUCT because the set of
VMStateDescriptions extends to structs defined by the devices.
Therefore, structs and cells cannot yet use vmstate_of!.

0d43ddae35 rust: vmstate: add new type safe implementation
The existing translation of the C macros for vmstate does not make
any attempt to type-check vmstate declarations against the struct, so
introduce a new system that computes VMStateField based on the actual
struct declaration.

Macros do not have full access to the type system, therefore a full
implementation of this scheme requires a helper trait to analyze the
type and produce a VMStateField from it; a macro "vmstate_of!" accepts
arguments similar to "offset_of!" and tricks the compiler into looking
up the trait for the right type.

The patch introduces not just vmstate_of!, but also the slightly too
clever enabling macro call_func_with_field!.  The particular trick used
here was proposed on the users.rust-lang.org forum, so I take no merit
and all the blame.

Introduce the trait and some functions to access it; the actual
implementation comes later.

Convert `unspecified` member of MemTxAttrs from bit field to bool, so

As a result, MemTxAttrs needs to be expanded from 4 bytes to 8 bytes.

Therefore, move `unspecified` to after the bit fields and add reserved
members to ensure that the whole structure is packed into 8 bytes.

0f9eb0ff2b rust/qdev: Make REALIZE safe
A safe REALIZE accepts immutable reference.

Since current PL011's realize() only calls a char binding function (
qemu_chr_fe_set_handlers), it is possible to convert mutable reference
(&mut self) to immutable reference (&self), which only needs to convert
the pointers passed to C to mutable pointers.

Thus, make REALIZE accept immutable reference.
