Hi Rakesh,
I have a beagle board and want to create a u-boot that verifies the kernel and rootfs before booting it. Any pointers on how it can be achieved will be appreciated.
You can start here by reading the provided documentation:

There's also a ELCE 2013 presentation by Simon Glass:

And a paper by Jagan Teki from the U-Boot Mini Summit

The mailing list is surely the right place for further questions ;)
One more paper to Detlev pointers! http://www.denx.de/wiki/pub/U-Boot/OpenSourceIndia2013/Multi_image_booting_s...
