Huaqi Fang 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.

Andrew Boie 9175d20ceb arc: fix CONFIG_ARC_STACK_CHECKING
- There's no clear need to disable frame pointers if this feature is
used, remove this directive.
- 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.

Andrew Boie fb2e5a4479 arc: add -fno-delete-null-pointer-checks
This option has side effects. It also tells the compiler not to generate
these checks in the first place. The checks call abort() which doesn't
exist in our environment.

This patch gets rid of linker errors due to missing abort() in the 0.9 SDK.

Kumar Gala 6102427e5d build: Introduce concept of SoC specific build flags
Introduce a soc-cflags, soc-cxxflags, and soc-aflags as a means for
SoC specific compiler flags to be set without manipulating Kbuild
options directly.

Alexandre d'Alton f91e55b798 arc: implement stack checking
ARC CPU has stack checking feature that allows to trigger an exception
whenever the stack is incorrectly accessed.
This patch implements the stack_top and stack_base register updates on
context switches, and activates the Stack Checking bit of STATUS32
register when the CPU is in the context of a fiber or task.
As GCC accesses the non-yet allocated stack with frame pointer enabled,
this patch also add the omit-frame-pointer gcc flag in order to work
properly.

Anas Nashif c4c919dbe0 Move compiler optimization to the SoC
Decisions on compiler optimizations were done on the architecture level,
this does not scale and some SoCs will have different optimization levels
or compiler options needed. Moving this to the SoC makes it easy to optimize
differently when using the same CPU which we use to set the right optimization
now on the architecture level.

For IAMCU platforms, use the right architecture and tuning.

Andrew Boie 1f63ec7264 Revert "Move compiler optimization to the SoC"
This reverts commit 778d5b11c5327be4b40c7745e9beaecfd6327e13.

This patch has been identified as breaking the build when trying
to manually build non-x86 applications.

Andre Guedes 1622e4f4b5 kbuild: Move CONFIG_STACK_CANARIES check
This patch moves the CONFIG_STACK_CANARIES check from architecture's
Makefile to the root Makefile since this option is kernel-related,
not architecture-related. This way we avoid replicating the same
CONFIG_STACK_CANARIES check in several Makefiles.

This patch also removes some blank lines from the Makefiles it touches.

Follow the model of the Linux kernel for adding arch
specific CFLAGS by using the Makefile and Kbuild combination
in the arch/<arch> directory.

This will also allow adding architecture specific targets and is
easy to maintain when alongside the architecture.
