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.
