boards are forced to enable PINCTRL.

72167f2acf drivers: flash: nrf_qspi_nor: Add support for XIP at boot
Adds support for forcing XIP support at boot time, and reduces the
init priority of the driver so that it inits earlier.

41c33d7f32 drivers: flash: nrf_qspi_nor: Fix writing from unaligned RAM buffers
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).

a529c4511d drivers: flash: Update drivers to use devicetree Kconfig symbol
Update flash drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.

We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

8e001191ce drivers/flash/nrf_qspi_nor: Default write_from_nvmc buffer size to 4
The commit changes the default size of write_from_nvmc,
defined by CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE, to 4,
making the write_from_nvmc operation enabled by default.
The Kconfig description for the option has been changes more clearly
describe how does the option impact compilation.

28447c84c3 drivers: flash: nrf_qspi: support JESD216 API
Refactor slightly so we can read SFDP tables with this driver.  Note
that the SFDP read command requires long frame mode transfers as data
exceeds 8 bytes.

3e46ae1acb drivers: flash: nrf_qspi: rework handling of quad-enable bit
Kconfig allowed selecting any bit in the status register as the QE
bit, and defaulted it to 6.  Devices need not require a QE bit at all,
and where JESD216 defines QE bit location the only place in first SR
byte that it can be is bit 6.  Further, the code unconditionally wrote
the value 0x40 without respecting configuration of other bits.  Some
of those bits control write protection of block-protected areas and
should not be changed.

Remove the Kconfig, instead using the jedec,jesd216-controlled
devicetree property.  Allow the driver to recognize whether or not
setting the bit is required, and when it is only use bit 6.  Only
update if the setting does not match the configuration.

f2ac844cf7 drivers: flash: nrf_qspi_nor: optionally support write from NVMC
The Nordic QSPI peripheral uses DMA transfers so data to write must be
located in SRAM.  Add a Kconfig that enables copying data from NVMC to
a stack SRAM buffer so it can be written to flash.

5b4f4253c1 drivers: flash: add Nordic JEDEC QSPI NOR flash driver
Most JEDEC NOR flash devices uses not only typical SPI mode
(MISO,MOSI,SCK and CS), but also QSPI mode (IO0,IO1,IO2,IO3,SCK and CS).
QSPI mode uses more data lines and as a result provide higher
throughput. If this were not enough, Nordic chips provide
hardware acceleration for read/write/erase functions, what
gives significant performance boost.
It does a lot of things "behind the scene", i.e when user has written
some data to the flash and would like to read them back, it has to wait
until the flash is ready by reading WIP bit in Status Register.
This driver does it automatically.
