/*
|
|
* This routine installs an interrupt vector on CPU architectures
|
|
* using the Simple Vectored Interrupt Model. This is the shared
|
|
* version which does nothing BSP specific. A BSP specific version
|
|
* will be needed if you need to enable an interrupt source via
|
|
* some register.
|
|
*
|
|
* INPUT PARAMETERS:
|
|
* handler - interrupt handler entry point
|
|
* vector - vector number
|
|
* type - 0 indicates raw hardware connect
|
|
* 1 indicates RTEMS interrupt connect
|
|
*
|
|
* OUTPUT PARAMETERS: NONE
|
|
*
|
|
* RETURNS:
|
|
* address of previous interrupt handler
