// Purpose:     Variant interrupt support
// Description: The macros defined here provide the HAL APIs for handling
//              interrupts and the clock on the PPC60x variant CPUs.
// Usage:       Is included via the architecture interrupt header:
//              #include <cyg/hal/hal_intr.h>
//              ...
//

// No builtin interrupt controller in the PPC60x CPUs.
