* Name: nx_start

* Description:
* This function is called to initialize the operating system and to spawn
* the user initialization thread of execution. This is the initial entry
* point into NuttX

* Input Parameters:
* None
*
* Returned Value:
* Does not return.

* Name: nx_smp_start
*
* Description:
* In an SMP configution, only one CPU is initially active (CPU 0). System
* initialization occurs on that single thread. At the completion of the
* initialization of the OS, just before beginning normal multitasking,
* the additional CPUs would be started by calling this function.
*
* Input Parameters:
* None
*
* Returned Value:
* Zero on success; a negated errno value on failure.

* Name: nx_idle_trampoline

* Input Parameters:
* Standard task arguments.

* Name: nx_bringup
*
* Description:
* Start all initial system tasks. This does the "system bring-up" after
* the conclusion of basic OS initialization. These initial system tasks
* may include:
*
* - pg_worker: The page-fault worker thread (only if CONFIG_PAGING is
* defined.
* - work_thread: The work thread. This general thread can be used to
* perform most any kind of queued work. Its primary
* function is to serve as the "bottom half" of device
* drivers.
*
* And the main application entry point:
* symbols:
*
* - USER_ENTRYPOINT: This is the default user application entry point.
*
* Input Parameters:
* None
*
* Returned Value:
* None
