more on U-Boot encryption vulnerabilties

Re: https://firmwaresecurity.com/2017/09/08/u-boot-aes-cbc-encryption-multiple-vulnerabilities/

I asked on the U-Boot mailing list for more information on this issue. The response from Tom Rini of Konsulko:

So, I mentioned this in the patch that migrated the option to Kconfig and marked it deprecated, and I plan to mention it in the release notes on Monday. But, this option has no in-tree users and I plan to remove the code in the near term, if no one with the relevant background steps up to re-implement it. Thanks!
