// Date:        2000-04-02

// Purpose:     Variant interrupt support

// Description: The macros defined here provide the HAL APIs for handling

//              interrupts and the clock on the PPC40x variant CPUs.

// Usage:       Is included via the architecture interrupt header:

//              #include <cyg/hal/hal_intr.h>

//              ...
