1bab5b6813 arch/arm/: Rename up_intstack_* to arm_intstack_*
The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all architecture-private functions begin with the name of the arch, not up_.

This PR addresses only these name changes for the ARM-private functions up_instack_base() and up_instack_top() which should be called arm_instack_base() and arm_instack_top().

There should be no impact of this change (other that one step toward more consistent naming).

Normal PR checks are sufficient

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).

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).

4892c27b4a Check return from nxsem_wait_uninterruptible()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is for all SPI drivers under arch/.

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.

* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

62a1f6f110 up_timer_initialize() is named incorrectly.
