984be5eb65 storage: flash map: Add FIXED_PARTITION(label) macro
The commit adds FIXED_PARTITION(label) macro that allows to obtain
struct flash_area object for partition of given label.
The macro allows instantiation of partition at point of usage
and will be replacing need for defining flash map with all partition
entries.
Area obtained with the macro should not be passed to open, instead
flash_area_device_is_ready, basically equivalent of device_is_ready
should be called on the obtained pointer to check if area is ready
for use.

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.

a593a733e8 storage: flash_map: handle disabled flash nodes
Don't fail to compile when `fixed-partition`'s exist on a flash device
that is disabled. This does not fix the case where a `fixed-partition`
is on a flash device with `status = "okay"` but with no driver compiled
in.

07fd28397e storage: flash_map: Fix partition device retrieval
Change the default behaviour of the flash partition choice when no
matching compatible is found. The new default is the grandparent node
of the fixed-partition.

As the grandparent node is what the jedec_spi_nor and nordic_qspi_nor
compatibles were selecting, remove these as separate checks.

This allows the flash_map API to be used for implementations of the
flash API other than the 3 originally specified (soc_nv_flash,
jedec_spi_nor & nordic_qspi_nor).

Fixes #26397

69c15f0ed1 dts: flash_map: Automatically generate of the list of flash area
This Patch add functionality for automatic generation of the flash map
using DTS description. Automatic generation allows to replace
C-hardcoded flash_map.

We generate a set of defines based on the index of a partiion:
	#define DT_FLASH_AREA_<IDX>_OFFSET	0
	#define DT_FLASH_AREA_<IDX>_SIZE	131072
	#define DT_FLASH_AREA_<IDX>_DEV		"FLASH_CTRL"
	#define DT_FLASH_AREA_<IDX>_LABEL	MCUBOOT

Additionally we also define:
	#define DT_FLASH_AREA_NUM		4

and:
	#define DT_FLASH_AREA_<PARTNAME>_ID	0

4954fe06f2 subsys: fs: fix generic storage partition selection
FS_FLASH_MAP_STORAGE keyword enables the storage partition,
but it was depend on flash_map module which is unused by
NFFS. This patch makes it independent thanks
to it is possible to enable the storage partition
without flash_map module.

FS_FLASH_MAP_STORAGE was renamed to
CONFIG_FS_FLASH_STORAGE_PARTITION
as it is independent for flash_map.

9968cda453 fs: Convert NFFS partition to a generic one
The NFFS partition at the end of flash is also useful for any other
file system or even the Flash Circular Buffer (FCB). Rename the
partition from 'nffs_partition' to 'storage_partition' and make it
depend on a new hidden Kconfig entry which the relevant users will
select (such as NFFS and FCB).
