* Name: up_initialize
*
* Description:
* up_initialize will be called once during OS
* initialization after the basic OS services have been
* initialized. The architecture specific details of
* initializing the OS will be handled here. Such things as
* setting up interrupt service routines, starting the
* clock, and registering device drivers are some of the
* things that are different for each processor and hardware
* platform.
*
* up_initialize is called after the OS initialized but
* before the init process has been started and before the
* libraries have been initialized. OS services and driver
* services are available.
*
