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?
