- *
- * t_yamon_register_esr
- * Description :
- * -------------
- *
- * Registers an exception handler, also known as an "Exception Service
- * Routine" (ESR) for the specified exception.
- *
- * Two special exception IDs are defined :
- * YAMON_DEFAULT_HANDLER used for a default ESR.
- * YAMON_DEFAULT_EJTAG_ESR used for EJTAG exceptions.
- *
- * The default ESR is called if no other ESR is registered
- * for an exception. If no default ESR is registered, a static
- * (i.e. not registered) "super default" function is invoked.
- * This function prints out the registers and halts.
- *
- * Deregistration of an ESR may be be done by calling this function
- * with 'esr' set to NULL.
- * An ESR can also be deregistered using the 'yamon_deregister_esr'
- * function.
- *
- * An ESR may be registered even if a previously registered
- * ESR has not been deregistered. In this case the previously
- * registered ESR is lost.
- *
- * The ESR will get called with registers in the state they were
- * when the exception occurred. This includes all CP0 registers and
- * CPU registers $0..$31, except for k0,k1 ($26,$27).
- *
- * In case an ESR does not want to handle the exception, it may
- * call the return function passed in the 'retfunc' parameter.
- *
- * Case 1 : 'retfunc' called by ESR registered for the
- * INTERRUPT exception.
- *
- * We assume an application has registered this ESR and wants
- * YAMON to process the (remaining) interrupts.
- *
- * Case 2 : 'retfunc' called by an ESR registered for a specific
- * exception (not INTERRUPT).
- *
- * Default handling will be done.
- *
- * Case 3 : 'retfunc' is called by the ESR registered as default ESR.
- *
- * The exception will be handled as though no ESR is registered
- * (i.e. the "super default" function is called).
- *
- * Parameters :
- * ------------
- *
- * 'exception' (IN) : Exception code
- * or YAMON_DEFAULT_HANDLER for a default ESR
- * or YAMON_DEFAULT_EJTAG_ESR for ejtag exceptions.
- * 'esr' (IN) : Function pointer for ESR.
- * 'ref' (OUT) : Handle used for deregistration of ESR.
- * 'retfunc' (OUT) : Pointer to function pointer for the return
- * function described above.
- *
- * Return values :
- * ---------------
- *
- * 0 : Registration went well.
- * Other values indicate error.

- *
- * t_yamon_register_cpu_isr
- * Description :
- * -------------
- *
- * Registers an Interrupt Service Routine (ISR) for the specified
- * CPU interrupt.
- * The highest service priority is attached to HW-INT5, which is
- * connected to the CPU-built-in CP0-timer. SW_INT0 gets the lowest
- * service priority. During registration, the interrupt mask field
- * in the CPU CP0-status register is updated to enable interrupts
- * from the specified interrupt source.
- *
- * A special ID is defined :
- * YAMON_DEFAULT_HANDLER used for a default ISR.
- *
- * The default ISR is called if no other ISR is registered
- * for a CPU interrupt.
- *
- * Deregistration of the default ISR may be done by calling
- * this function with 'isr' set to NULL.
- * Also, a new default ISR may be registered even if a
- * previously registered ISR has not been deregistered.
- * ISRs for specific CPU interrupts must be deregistered using
- * 'yamon_deregister_cpu_isr'.
- *
- * Parameters :
- * ------------
- *
- * 'cpu_int' (IN) : CPU interrupt (0..7)
- * or YAMON_DEFAULT_HANDLER for a default ISR.
- * 'isr' (IN) : Function pointer for ISR.
- * 'data' (IN) : Data pointer (may be NULL). Will be passed to
- * ISR when called.

- *
- * t_yamon_register_ic_isr
- * Description :
- * -------------
- *
- * Registers an Interrupt Service Routine (ISR) for the specified
- * source in the interrupt controller.
- *
- * A special ID is defined :
- * YAMON_DEFAULT_HANDLER used for a default ISR.
- *
- * The default ISR is called if no other ISR is registered
- * for an interrupt.
- *
- * Deregistration of the default ISR may be done by calling
- * this function with 'isr' set to NULL.
- * Also, a new default ISR may be registered even if a
- * previously registered ISR has not been deregistered.
- * ISRs for specific interrupts must be deregistered using
- * 'yamon_deregister_ic_isr'.
- *
- * Parameters :
- * ------------
- *
- * 'ic_line' (IN) : Interrupt source line in Int. Controller
- * or YAMON_DEFAULT_HANDLER for a default ISR.
- * 'isr', (IN) : Function pointer for user defined ISR.
- * 'data' (IN) : Data pointer (may be NULL). Will be passed to
- * ISR when called.
- * 'ref', (OUT) : Handle used for deregistration of ISR.
- *
- * Return values :
- * ---------------
- *
- * 0 : Registration went well.
- * Other values indicate error.
