[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

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.

The simple answer is: DON'T.
