Hi All,

I want to know how to use the interrupt in u-boot.

My development environment is like below,

- AP : i.MX257

- Board : i.MX25-PDK

- u-boot version : u-boot-2009.08

Actually I know the u-boot are using the polling mode in the all peripherals.

But I have to apply the interrupt mode for the GPIO and GPT.

Could you give me the method how to apply the interrupt mode in the u-boot?

Best Regards,

Eric.
