I finally managed to get runtime updates to the key databases and the
platform keys to work on the Tianocore UEFI emulator. The code is in
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/efitools.git
And a description of how to use the tools is here:

This means (provided we have access to the relevant keys) we can move
the platform into and out of Setup Mode as well as add signing and other
keys.
