Hi,
In start.S file irq_handler code is used for handling the irq
interrupts though iam able to handle the interrupt, iam not able to restore
the previous state. irq_restore_user_regs label is given generally in all
u-boots for restoring the state but not happens. Please do needful how i
come out from this.
Thanks
balaji

It is going to be a bit difficult to advise you without knowing which
architecture, which target, and which release of U-boot you are using,
and what exactly happens.
