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
Rationale: TM4C1294NC is ambiguous:
TM4C1294NCPDT is a 128-TQFP
TM4C1294NCZAD is a 212-NFBGA
The TM4C1294NC part currently supported by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL "Connected LaunchPad" (see configs/tm4c1294-launchpad). To ensure the correct part is fully specified, this commit updates all TM4C1294NC identifiers to TM4C1294NCPDT.
Rename:
CONFIG_ARCH_CHIP_TM4C1294NC to CONFIG_ARCH_CHIP_TM4C1294NCPDT
ARCH_CHIP_TM4C1294NC to ARCH_CHIP_TM4C1294NCPDT
TM4C1294NC to TM4C1294NCPDT
arch/arm/src/tiva/hardwar: Move LM3S and LM4F include files to hardware/lm/ sub-directory. Move all TM4C header files files to hardware/tm4c/ sub-directory.
arch/arm: Add basic configuration/build support for CC13xx parts. Conditioned on EXPERIMENTAL.
Squashed commit of the following:
arch/arm/src/tiva/Make.defs: Trivial change to conditional VPATH.
arch/arm/src/tiva: Move LM3S and LM4F source files to lm/ sub-directory. Move all TM4C source files to tm4c sub-directory.
arch/arm/src/tiva and configs/: Change include patch from chip/ to hardware/ in all Tiva files includes.
arch/tmp/src: Rename chip/ subdirectory to hardware/. This is a better name since it does not conflict with other directory names and, well, we are going to be change a lot of the Tiva directory structure in the next few commits.
