I am using u-boot for my custom PXA250 board and am in the process of trying to get the board to use the power management suspend/resume feature in linux.

I am able to put the cpu into suspend mode, but I can never get it to wake-up. I am under the impression that it is the bootloader that needs to handle the wake-up and pass control back to linux.

Has anyone been able to add resume support into u-boot for a PXA?
