[U-Boot-Users] Registering Interrupt Handlers for ARM920T-Based boards

Hi Group,

How do I register an interrupt handler in U-Boot? My customer is persistent in flow controls in binary image downloading. I am now free to support hardware flow control or XON/XOFF. Can somebody please give me guidelines on how to create support for hardware flow control on my ns16550-based serial driver? I am using smdk2410 as my template. Maybe, the initial step is how do I register my interrupt handlers?

Thank you very much for your time.

Best Regards,

Rodel Miguel
