Here's my repository:
https://git.linaro.org/people/takahiro.akashi/u-boot.git efi/secboot

But it's quite old and not ready for public review, yet it works in some way.
Since then, I've done
- implementing image authentication as close to EDK2's semantics as possible,
  including timestamp-based revocation
- improving portability of linux-kernel-based pkcs7/x509 parsers
- reworking the code in general for better maintainability
- adding initial automated testing of image/variable authentication
  based on pytest framework

On the other hand, Sughosh and Pipat are working on integrating
StMM-based UEFI variables/secure storage into U-Boot.

As far as my part is concerned, my plan is that I will focus on developing
more test cases and verifying the authentication code. Once I have some good
confidence, I'd like to submit the patch set.
It will be around the next Connect, I guess?

Thanks,
-Takahiro Akashi
