[U-Boot-Users] U-Boot code checksum?

Does the U-Boot code generate and check a checksum or CRC on itself? I see code to verify CRC checksums on images that U-Boot loads into memory, but I do not see any code that checks the U-Boot image itself.

If there is a function that checks the U-Boot CRC or checksum, could someone point it out to me?

We burn the U-Boot code into a boot PROM and I need some way of verifying the boot PROM was burned correctly when the system powers up. I've written checksum generation and verification utilities in the past but would prefer to use the utilities that come with U-Boot if they exist.

Thank you,
