 *    Module Name:

 *
 *    Abstract:
 *          System Interrupt definitions for OAL layer.  SYSINTR_FIRMWARE is
 *       defined in nkintr.h.  The OAL can use any values in the range
 *       SYSINTR_FIRMWARE thru SYSINTR_MAXIMUM.

// Note : The CEPC is a bit unusual since we allow various
// cards to be a different addresses without actually defining
// a new platform.  So, for those drivers there is no need
// to define an actual SYSINTR value.  Just use MapIrq2SysIntr
// to get a SYSINTR ID that matches the physical interrupt.
// The only exception is keyboard/mouse which is always at 
// IRQ 1/12.
#define SYSINTR_KEYBOARD    (SYSINTR_FIRMWARE+1)
#define SYSINTR_TOUCH       (SYSINTR_FIRMWARE+12)

// And Audio hasn't been modified yet, but should be.
#define SYSINTR_AUDIO       (SYSINTR_FIRMWARE+4)

//
// CEPC device drivers should get their IRQ number from the registry and use
// MapIrq2SysIntr to get the appropriate SYSINTR_* number to use.
