arch/arm: adds initial support for Atmel SAM3X8E processor This adds initial support for Atmel SAM3X8E processor, which is based on ARM Cortex-M3. The SAM3X8E is being used on Arduino Due. Change-Id: I199efcf29629f9ebacad474e5edc91bc3757f613 Signed-off-by: Daniel Leung <daniel.leung@intel.com>

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>
