* 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.
|
|
