Summary The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private files begin with the name of the architecture, not up_. This PR addresses only these name changes for the up_*.h files. There are only three, but almost 1680 files that include them: up_arch.h up_internal.h up_vfork.h The only change to the files is from including up_arch.h to arm_arch.h (for example). The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm. Impact There should be not impact of this change (other that one step toward more consistent naming). Testing stm32f4discovery:netnsh
