[U-Boot] U-Boot loads and verifies a second U-Boot on beaglebone

[pratap]

Hi All,
         Inspired by simon's advice posted on LWN regarding verifying the
signature of secondary uboot and thereby loading the kernel + devicetree +
ramfs.


I would be  thankful if i can get reference  codebase for beaglebone, as
stated below on LWN forum

*"On a BeagleBone Black (OMAP4), it takes about 6ms to verify a
configuration and only adds 6.2KB to U-Boot's code size"*


Thanks to simon for the following reference chromeos project:

Thanks,
pratap
