+/*
+ *  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
