Flash API states that drivers should support write requests without
any restrictions on location or alignment of the source buffer.
Due to hardware limitations of the QSPI peripheral, the nrf_qspi_nor
driver currently fails to perform a write from a RAM buffer that is
not word-aligned. Fix this by using in such case the same mechanism
that is used when the source buffer is located in the internal flash
(copy data to a buffer located on stack).
Also correct the length parameter for writes from this stack-based
buffer to be the actual data chunk length, not always the size of
the buffer (as for CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE > 4
this may lead to overwriting of some data located next in the flash).

Normally, the driver deactivates the QSPI peripheral for periods when
no QSPI operation is performed. This is done to avoid increased current
consumption when the peripheral is idle. For the same reason, the base
clock on nRF53 Series SoCs (HFCLK192M) is configured for those periods
with the default /4 divider that cannot be used otherwise. However,
when XIP accesses are used, the driver must be prevented from doing
both these things as that would make XIP to fail. Hence, a function
is provided so that applications can inform the driver that XIP is
needed and the above idle actions should be suppressed.
This function (`nrf_qspi_nor_xip_enable()`) replaces the old one
(`nrf_qspi_nor_base_clock_div_force()`) that was intended for similar
purpose but after deactivation of the peripheral was introduced in
commit 95d867e8ed it became useless.

Introduce flash extended operations that can be used to disable access
to option and control registers until reset. Disabling access to these
registers improves system security, because flash content (or protection
settings) can't be changed even when exploit was found.
On STM32 devices, registers can be locked until reset by writing wrong
key during unlock procedure. It triggers a bus fault, so during the
procedure we need to ignore faults and clear bus fault pending bit.
Please note that option register disabling was implemented for devices
that have OPTCR register (F2, F4, F7 and H7). Implementation on other
devices requires more testing, since documentation is not precise
enough. Disabling control register was implemented for devices that

Besides of standard flash operations like write or erase, flash
controllers also support additional features like write protection or
readout protection. These features are not available in every flash
controller, what's more controllers can implement it in a different way.
It doesn't make sense to add a separate flash API function for every
flash controller feature, because it could be unique (supported on small
number of flash controllers) or the API won't be able to represent the
same feature on every flash controller.
Extended operation interface provides flexible way for supporting flash
controller features. Code space is divided equally into Zephyr codes
(MSb == 0) and vendor codes (MSb == 1). This way we can easily add
extended operations to the drivers without cluttering the API or
problems with API incompatibility. Extended operation can be promoted
from vendor codes to Zephyr codes if the feature is available in most
flash controllers and can be represented in the same way.

In flash_stm32_page_layout, the FLASH_PAGE_NB macro is used to set the
page count in the flash layout returned to the caller. On STM32L5
platforms this is defined in stm32l5xx_hal_flash.h to be (FLASH_SIZE /
FLASH_PAGE_SIZE). However, on STM32U5 platforms the macro is defined in
the soc headers (such as stm32u585xx.h) define the macro as
(FLASH_BANK_SIZE / FLASH_PAGE_SIZE). This results in the flash layout
only reflecting the first bank on STM32U5 platforms with the maximum 2
MB of flash.
This commit resolves this discrepancy by directly calculating the number
of pages by dividing FLASH_SIZE by FLASH_PAGE_SIZE.
Tested on a proprietary board using the STM32U585 which mounts a
littlefs partition in the last 256 kB of its 2 MB of flash.

Unlocking CR at the end of initialization was added in commit
a9183cd518. It was probably copied
from previous flash driver implementation.
Unlocking and locking CR in write and erase functions was added in
commit 6e4cdb0c99. Since we always unlock
the register before writing or erasing, and lock it after the operation
is finished, there is no need to unlock it after initialization.

Previously, while writing close to the start of flash (i.e: in the first
row), the write was never committed - due to zero being used as the
"empty buffer" marker.
This patch also incorporates some performance improvements, as well as
observing any errors reported by `flash_sam0_commit()`.

Instead of calling __HAL_RCC_OSPIM_CLK_ENABLE() to enable the OSPI
manager clock, we now use a new clock binding in the dts.
In order to avoid confusion between the different clocks, the driver
is modified to select the clock based on their names instead of indexes.

After a soft-reset of the host controller the flash device is not reset.
This can cause the flash device to still be busy writing or erasing when
the host controller boots and initializes the flash. The often results
in errors and the flash device not being initialized.
This fix polls the status register until the WIP flag is off before
initializing the flash device.

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.

We have been encountering timeout issues when erasing large flash
sections (before receiving an image via mcuboot) from this semaphore
take:
5af0fbc2e3/drivers/flash/soc_flash_nrf_ticker.c (L225-L233)
I think this is because this constant is based on the time taken to erase
the chip but doesn't take account of the fact it is being done by a
ticker. If I understand correctly the ticker is a timeshare mechanism
so the actual max erase time is some factor based on how much time is
given to the task by the ticker.
This multiplies the max timeout by 1.5

If the flash is used in 4-byte addressing, reading SFDP will fail after
a system reset if the flash isn't power cycled or hardware reset, since
Zephyr will try to use 3-byte addressing while the flash (still) expects
4-byte addressing.
This commit adds the ability to send a reset command to the flash as part
of initialization, which complements the existing reset-gpio
functionality, and is useful on low-pincount flashes which do not have a
hardware reset.
