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.

Kbuild: fixed arc compiler options This was messed up due to lack of arc platform to test. Change-Id: I5abda172dddf54532c1bcb66f36d02db7f7d7ff4 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

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.

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. -march=lakemont -mtune=lakemont -miamcu -msoft-float Change-Id: I458afca5feb9be5de8dcae559d6dcac3c6d6a2a7 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

new SoC naming convention Use SOC_FAMILY and SOC_SERIES to identify soc families and series and to point to the correct linker files and files related to a specific SoC. Change-Id: I8b1a7339f37d6ea4161d03073d36557a40c0b4a6 Signed-off-by: Anas Nashif <anas.nashif@intel.com>
