ARCv2 cores may access data not aligned by the data size boundary.
I.e. read entire 32-bit word from address 0x1.
This feature is configurable for ARC EM cores excluding those with
secure shield 2+2 mode. When it's available in hardware it's required
to enable that feature in run-time as well setting status32.AD bit.

KFLAG instruction might affect multiple flags in STATUS32 register
and so when we need just AE-bit to be reset we need first read current
state of STATUS32, then change our bit and set STATUS32 again.
Otherwise critical flags including stack checking, unaligned access etc
will be dropped for good.

Up until now only ARC EM family has been supported in Zephyr
which don't support atomic operations other than
compare-and-excange, so custom atomic ops with load-locked(LLOCK)/
store-conditional(SCOND) were never used that's how we never
realised CONFIG_ATOMIC_OPERATIONS_CUSTOM points to the wrong file:
"atomic.c" while real implementation is in "atomic.S".
Fix that now.

Changes related to Bluetooth TSE 11068.
This is done because the current test suite does not issue
an LE Enable Address Resolution command anymore in RPA
generation tests. Makes sense now that the Bluetooth SIG has

The call to bt_conn_security will send a SMP security request for
peripheral, and for central it will initiate LL encryption.
A call to bt_conn_security with no IO capabilities but authenticated
keys has been distributed, would succeed on central side, but fail on
peripheral side with error code -22.
The keys could have been either:
- Preprogrammed
- IO capabilities may have changed.
- OOB bonding may been used.
Fix so that Peripheral can send a security request if the bond
information is already established.

The content of subsys/fb/cfb_fonts cannot be replicated by the existing
script due to lack of positioning options and use of a full-color frame
buffer, which affects the generated bitmap. Switch to the solution used
in the original script, add the required options, and document the
process of regenerating the fonts.
This commit also determines the required bounding box for the glyphs to
be sure that the user-provided value is sufficient to avoid partial
characters. Ideally the calculated width and height would be used for
font characters, but this would require significant restructuring of the
script to make calculated values available at the point where the
arguments are used to produce output.

The output of this script is intended to be put into an implementation
file, where the font data is accessed by index to an array maintained by
the linker script. There is no need for protection against multiple
includes, and the font data array should not be a global symbol.

The specified order of fields wastes space when the cfb_font_caps enum
isn't packed. Reorder to avoid this behavior.
Also remove the unnecessary array size on the extern symbol declaration,
lest the compiler misinterpret the properties as being zero-length
arrays rather than pointers. (The idiom is already technically
using undefined behavior since we're relying on the linker rather than
the language to produce an array from the individual declarations.)

The original creates a pointer to a compiler-generated temporary that is
destroyed when the scope is exited. The pointer is stored in a structure
defined in an enclosing scope and is invalid by the point it's used.
The fix holds the structure in a variable with the same lifetime as
the pointer.

The method for getting a memory usage report printed during build, is
based on a GNU linker (ld) option flag, and thus is not necessarily
supported by other toolchain binary tools.
The introduced cmake macro allows for a given toolchain to specify how
the memory usage report is to be generated, and whether the command for
generation, if any, is to be added to the post_build_commands and the
post_build_byproducts lists of the top level CMakeLists.txt
The intent here is to abstract Zephyr's dependence on toolchains,
thus allowing for easier porting to other, perhaps commercial,
toolchains and/or usecases.
No functional change expected.

This forms the foundation for the abstraction of the binary tools,
where the following steps are taken:
- Move binary tool resolving, such as objcopy, objdump, readelf and
so forth, out of compiler definitions and place in a dedicated binary
tools folder with the binary tools supplier as subfolder, similar to
the compiler and linker directories.
- Create binary tool sets, gnu, host-gnu and llvm.
- Each toolchain selects the required set of binary tools by setting
BINTOOLS via its generic.cmake as it also does for compiler and linker.

We generated a define for each instance to convey its existance of the

However we renamed all other instance defines to be of the form
DT_INST_<INSTANCE>_<FOO>. To make things consistent we now generate a
define of the form:
#define DT_INST_<INSTANCE>_<COMPAT> 1
We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses
to use the new form.
