[U-Boot-Users] How to add Timer Interrupt to u-boot?

[Robert]

Hello all:

    Everybody knows how to add Timer Interrupt to the u-boot?
I wrote a fuction called timer0_isr(), and wanted to add it to Uboot,
but I didn't know what to do,  Does the uboot has a funciton like
function  request_irq() in linux kernel?
    Thanks in advance!

With kind regards,
