- Included a collection of cpu-dependent headers in core/include/arch - Extracted all interfaces that need to be implemented for a cpu - Created a mapping between those interfaces and the old ones - added flag for disabling arch interface - added missing state to lpm_arch interface - added arch interface for reboot - fixed newline issues that were pointed out - documentation fixes to cpu-core interface
