hi,
When using the function:
int request_irq (unsigned int irq,
irq_handler_t handler,
unsigned long irqflags,
const char * devname,
void * dev_id);
To connect an ISR to one of the processor's
peripherals irq (SCC in my case).
Which value I should use for irqflags,
from the list in: interrupt.h file.
Kernel 2.6.24
Processor: MPC8272
Thanks,
Liran.

Just pass zero (or IRQF_SHARED if the IRQ is shared, but it shouldn't be
in this case).
