65edd8433c soc: riscv: andes_v5: add Andes EXEC.IT option
Andes EXEC.IT (Execution on Instruction Table) is supported by Andes
toolchain only. Andes toolchain will replaces suitable 32-bit instructions
with the 16-bit "exec.it <INDEX>" in which <INDEX> points to a
corresponding 32-bit instruction in look up table.

710422ec5e include/zephyr: Fix linker scripts to define _end after all static RAM data
The Zephyr linker scripts have inconsistent ordering of various chunks of
data which lands in RAM at runtime. This leads to the value of _end not
being consistently defined as the maximum address of static variables used
in the application.

Create a helper linker fragment, zephyr/linker/ram-end.ld, which can be
included after the last possible definition of RAM data, that consistently
sets _image_ram_end, _end and z_mapped_end.

As a result of the 11a2107d991b("riscv: timer: driver revamp") commit,
gd32vf103 no longer works properly.

In the
c9c04e491e0f("soc: riscv: Add initial support for GigaDevice GD32V SoC")
that is the first commit of implementation of this SoC,
set the CPU frequency to CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC,
and riscv_machine_timer divide the clock with the value of
CONFIG_RISCV_MACHINE_TIMER_SYSTEM_CLOCK_DIVIDER.

The CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC should set the timer's clock,
so I fixed to set the config as 27MHz in this PR.  Also, remove the
unnecessary CONFIG_RISCV_MACHINE_TIMER_SYSTEM_CLOCK_DIVIDER setting.

28a18ece43 soc: riscv: riscv-privilege: opentitan: Enable watchdog reset function
Adds watchdog reset as a reset source at SoC init. This is achieved by:

1. Writing 0x2 to the RESET_EN bitfield register to indicate watchdog
reset is enabled.
2. Writing 0x1 to the CFG_CDC_SYNC register to commit the change.
3. Polling the CFG_CDC_SYNC register until reading 0 to confirm the
change has been processed.

This patch is part of the OpenTitan watchdog (AON Timer) support patch
series. It is needed to ensure that the watchdog reset functionality
is enabled. Note that the timer itself is not enabled here, only the
reset function.

a5fd0d184a init: remove the need for a dummy device pointer in SYS_INIT functions
The init infrastructure, found in `init.h`, is currently used by:

- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices

They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:

```c
struct init_entry {
	int (*init)(const struct device *dev);
	/* only set by DEVICE_*, otherwise NULL */
	const struct device *dev;
}
```

As a result, we end up with such weird/ugly pattern:

```c
static int my_init(const struct device *dev)
{
	/* always NULL! add ARG_UNUSED to avoid compiler warning */
	ARG_UNUSED(dev);
	...
}
```

This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:

```c
static int my_init(void)
{
	...
}
```

This is achieved using a union:

```c
union init_function {
	/* for SYS_INIT, used when init_entry.dev == NULL */
	int (*sys)(void);
	/* for DEVICE*, used when init_entry.dev != NULL */
	int (*dev)(const struct device *dev);
};

struct init_entry {
	/* stores init function (either for SYS_INIT or DEVICE*)
	union init_function init_fn;
	/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
	 * to know which union entry to call.
	 */
	const struct device *dev;
}
```

This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.

**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

ab2515ad26 it8xxx2: support relocating ISR code to RAM
IT8xxx2 uses a relatively slow SPI flash for ROM with a small 4k
I-cache. As a result in large or busy applications, instruction fetch
can be very costly due to I-cache misses. Since exception handling code
is some of the hottest code in most applications, add an option (enabled
by default) causing that code to execute out of RAM in order to improve
performance.

This is very similar to exception section placement on XIP niosii
platforms (which has similar motivation), but can still be disabled by
configuration.

d4549ed808 it8xxx2: generalize ILM support
Executing code out of RAM on IT8xxx2 requires that the relevant
addresses be mapped onto the CPU's instruction memory bus, referred to
by ITE documentation as Instruction Local Memory (ILM). ILM mappings
configure blocks of RAM to be used for accesses to chosen addresses when
performing instruction fetch, instead of the memory that would normally
be accessed at that address.

ILM must be used for some chip features (particularly Flash
self-programming, to execute from RAM while writing to Flash), and has
historically been configured in the Flash driver. The RAM for that was
hard-coded as a single 4k block in the linker script.  Configuring ILM
in the flash driver is confusing because it is used by other SoC code as
well, currently in code that cannot depend on the Flash being functional
or in hand-selected functions that seem performance-critical.

This change moves ILM configuration to a new driver and dynamically
allocates RAM to ILM in the linker script, allowing software use of the
entire 64k RAM depending on configuration.  This makes ILM configuration
more discoverable and makes it much easier to correctly support the
CODE_DATA_RELOCATION feature on this SoC.

c107827bb7 linker: correct linker script _flash_used calculation
Linker scripts contains a `.last_section` section that is placed in rom
region as NOLOAD for the purpose of retrieve the actual number of bytes
contained in the image. See d85efe0b10

However, a previous section may cause the location counter to be
incremented for alignment purposes. This can result in the size of the
image to be 0x10FA but location counter to be 0x1100 because it has been
aligned for next section placement.

Therefore, two new Kconfig settings are introduced.
Those settings request the linker to will write a pattern in
`.last_section`. Together with removing NOLOAD and writing a patten to
the section then we ensure that data is written after alignment of
location counter, and thereby forces the image size to be in sync with
the location counter.

The default pattern used will be 0xE015 (end of last section).

Some systems may fill up the flash completely, or simply write data at
the end of the flash, which in both cases can result in overflow.
Therefore, the new settings can be disabled.

4aa31b4526 drivers: clock_control: gd32: initial support
This patch adds a clock control driver for GD32 platforms. It is
important to note that the driver is only able to handle peripheral
clocks, but not "system clocks" (e.g. PLL settings, SYS_CK, etc.).  On
some similar platforms (STM32) this task is embedded in the same clock
driver, performed at init time but with no options to do any
manipulation at runtime via the API calls. The clock control API as-is
is really orthogonal to "system clocks", and it is arguably a bad idea
to embed system clock init code in a clock control driver. It can be
done at SoC level still using Devicetree as a source of hardware
description/initial configuration.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
   0.52ms(2.4ms->1.88ms) compared to the original pio mode when the

for RV32IAFC so builds fail at link-time. An appropriately-configured
compiler (such as GCC configured with
`--with-multilib-generator=rv32iac-ilp32--f`) can support such a build
however, so don't lie about the presence of an FPU.

This doesn't affect existing builds because CONFIG_FPU gates use of the
FPU, and is off by default. Enabling CONFIG_FPU will require an
appropriately-configured compiler, possibly also requiring careful
choice of CONFIG_FLOAT_HARD.

Now that PWM drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by

Typically the Kconfig.defconfig* will blindly enable a

04c6d7569f ITE: drivers/i2c: Add command queue mode
Adding command queue mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.

I2C command queue mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.

Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
   0.72ms(2.54ms->1.82ms) compared to the original pio mode when the
   frequency is 100KHz.
3. krabby platform can boot normally.
