[U-Boot] About the CRC of u-boot.bin

Our product is used in a safety-critical situation. We want to make
sure that the product we released is exactly the one we tested in our
labs.
Because our product is released in a checkout-build-release process,
it is impossible to just give out the binary file we tested.

Maybe there is a workaround to solve this problem.
