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

You don't. U-Boot does not need interrupts. Everything can be done using polling drivers.

Tell him that no such thing is needed. Serial download works poerfectly fine withouty flow control.
