* 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 user
|
|
* initialization logic has been started and before the libraries have
|
|
* been initialized. OS services and driver services are available.
|
|
*
