053857e09a storage/flash_map: Added function for get erased byte value
Added flash_area_erased_val() function for get value of erased
byte of memory which is under flash area.
This function already exist in MCUBoot and zephyr dfu subsystem
which makes simultaneous usage of both impossible.

8165008f44 dts: remove legacy macro support
The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.

This leaves support for legacy binding syntax in place. Removing that
is left to future work.

We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.

Adjust a couple of kconfigfunctions.py and sanitycheck bits to use
non-legacy edtlib APIs.

eb0f571790 storage: flash_map: Add SHA-256 integrity method
Add SHA-256 flash integrity method.  It reads flash data from a
device giving an offset creating a SHA-256 hash to be compared
with a reference.  On sucess match, zero is returned, otherwise
a negative errno value.

e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

-struct device *

@r_const_dev_2

Fixes #27399

4f7f6c96be includes/storage/stream_flash: clarification on API usage
Clarify that number of bytes_written means bytes number of bytes
written belongs to the user's payload.

Added API note for emphasize that any flush write should be
the last write operation in any writes row.

6554a5e5b6 include: rearrange for standard use of extern "C" in various headers
Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.

The inclusion of the generated syscall files is placed outside the
extern "C" block as the generated file has its own extern "C" block.

Background from issue #17997:

Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.

Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

See: https://en.cppreference.com/w/cpp/language/language_linkage

83508a5677 cleanup: include/: move flash_map.h to storage/flash_map.h
move flash_map.h to storage/flash_map.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
