2aa85fd17e arch/arm, board/arm: Rename all up_* functions to arm_*
Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private functions begin with the name of the architecture, not up_.

This PR addresses only these name changes for the ARM-private functions prototyped in arm_internal.h

This change to the files only modifies the name of called functions.  nxstyle fixes were made for all core architecture files.  However, there are well over 5000 additional complaints from MCU drivers and board logic that are unrelated to to this change but were affected by the name change.  It is not humanly possible to fix all of these.   I ask that this change be treated like other cosmetic changes that we have done which do not require full nxstyle compliance.

Impact

There should be not impact of this change (other that one step toward more consistent naming).

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_*.S files.

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.

037c9ea0a4 arch/arm: Rename all up_*.h files to arm_*.h
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).

6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

3e6c196ffa arch/ and config/ files: All board interfaces (those starting with board_) must be defined in board-specific logic. Otherwise, they cannot be customized of specialized usage by different boards. The board_reset() interface was defined in architecture-specific logic that only called up_systemreset(). That is useless!
This change removes the board_reset() implementation from the architecture-specific code and re-implements in the src/ directory of each board that has CONFIG_BOARDCTL_RESET enabled.  That is the correct functional partitioning.

62a1f6f110 up_timer_initialize() is named incorrectly. The prefix should be the architecture name, not up_ since it is private to the architecture. up_timerisr() is similarly misnamed and should also be private since it is used only with the xyz_timerisr.c files.
