9bc69a46fa boards: Update arc em_starterkit support from 2.2 to 2.3
Here are the main changes:
* board: Update EMSK onboard resources such as Button, Switch and LEDs
  + update soc.h for em7d, em9d, em11d
  + update board.h for em_starterkit board
* arc: Add floating point support and code density support
  + add kconfig configuration
  + add compiler options
  + add register definitions, marcos, assembly codes
  + fixes in existing codes and configurations.
* arc: Update detailed board configurations for cores of emsk 2.3
* script: Provide arc_debugger.sh for debugging em_starterkit board
  + make BOARD=em_starterkit debug
    This will start openocd server for emsk, and arc gdb will connect
    to this debug server, user can run `continue` command if user just
    want to run the application, or other commands if debugging needed.
  + make BOARD=em_starterkit debugserver
    This will start an openocd debugger server for emsk, and user can
    connect to this debugserver using arc gdb and do what they want to.
  + make BOARD=em_starterkit flash
    This will download the zephyr application elf file to emsk,
    and run it.

acc9fb29a3 arm: core: mpu: Add arm core MPU interface
This patch adds the arm core MPU interface, a common way to access the
pu functionalities by the arm zephyr kernel.

The interface can be divided in two parts:
- a core part that will be implemented by the arm_core_mpu driver and
  used directly by the kernel
- a driver part that will be implemented by the mpu drivers and used by
  the arm_core_mpu driver

This patch adds initial MPU support to NXP K6x family.
The boot configuration prevents the following security issues:
* Prevent to read at an address that is reserved in the memory map.
* Prevent to write into the boot Flash/ROM.
* Prevent from running code located in SRAM.

Clean-up the pinmux arrays as a preparatory work before adding more

This is achieved by the following two actions:
- Define the PAD macro to simplify the [x - 1] = y construct
- Reorder the declartions by bank / pin to make it easier to
  locate a pin among a high number of other pins, while minimizing the
  risk of conflict when two people add a new declaration for two
  different pins

- There's no clear need to disable frame pointers if this feature is

- The 'top' and 'base' terms are reversed. The 'base' is the high
address of the stack. The top is the lowest address, where we cannot
push further down. Fixup member and offset names to correspond to how
these terms are used in hardware documentation.
- Use correct pointers for stack top location
- Fatal exceptions now go through _NanoFatalErrorHandler to report the
faulting ip and thread.

174f301147 build: simplfy how extra build steps are specified
For various reasons its often necessary to generate certain
complex data structures at build-time by separate tools outside
of the C compiler. Data is populated to these tools by way of
special binary sections not intended to be included in the final
binary. We currently do this to generate interrupt tables, forthcoming
work will also use this to generate MMU page tables.

The way we have been doing this is to generatea "kernel_prebuilt.elf",
extract the metadata sections with objcopy, run the tool, and then
re-link the kernel with the extra data *and* use objcopy to pull
out the unwanted sections.

This doesn't scale well if multiple post-build steps are needed.
Now this is much simpler; in any Makefile, a special
GENERATED_KERNEL_OBJECT_FILES variable may be appended to containing
the filenames to the generated object files, which will be generated
by Make in the usual fashion.

Instead of using objcopy to pull out, we now create a linker-pass2.cmd
which additionally defines LINKER_PASS2. The source linker script
can #ifdef around this to use the special /DISCARD/ section target
to not include metadata sections in the final binary.

3d3d6a85df x86: remove hacks to include functions
None of this is currently necessary, the spurious interrupt
stubs and exception entry code is included in the binary just
fine. To make matters worse, some data referenced lives in the
.intList section which is completely stripped out of the binary.

If in the future we find certain essential functions are being
garbage collected when they should not be, the proper way to
mitigate this is with KEEP() directives in the linker script.

d26cf2dc33 kernel: add k_thread_create() API
Unline k_thread_spawn(), the struct k_thread can live anywhere and not
in the thread's stack region. This will be useful for memory protection
scenarios where private kernel structures for a thread are not
accessible by that thread, or we want to allow the thread to use all the
stack space we gave it.

This requires a change to the internal _new_thread() API as we need to
provide a separate pointer for the k_thread.

By default, we still create internal threads with the k_thread in stack
memory. Forthcoming patches will change this, but we first need to make
it easier to define k_thread memory of variable size depending on
whether we need to store coprocessor state or not.
