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

/* Don't change the current basic clock configuration if we are running

|
* from SDRAM. In this case, some bootloader logic has already configured
|
|
* clocking and SDRAM. We are pretty much committed to using things the
|
|
* way that the bootloader has left them.
|
|
*
|
|
* Clocking will be configured at 792 MHz initially when started via
|
|
* U-Boot. The Linux kernel will uses the CPU frequency scaling code
|
|
* which will switch the processor frequency between 400 MHz and 1GHz based
|
|
* on load and temperature. For now, NuttX simply leaves the clocking at
|
|
* 792MHz.
