[U-Boot] Backup Booting

[Pawel Pastuszak]

Hi Guys,

I was wondering if there is any think like backup booting and secondary
image for example lets say i am booting an image and it fails CRC check
etc... i want to to validate that the backup image is good and then
overwrite the current image with the backup image  and be able to boot of
the backup image.


 Second option of failure is image start booting and it fails in middle of
booting maybe watchdog kicks in and reset the board. Is there a way to tell
image fail booting and uses back instead.
