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>

    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.

Makefile Build system: Remove fixed lib/ subdirectory and its content. Replace with new directory called staging/ that is created dynamically when building and removed when 'make clean' is done. This both improves the name and eliminates a garbage directory from the repository. 2018-05-29 11:36:21 -06:00
