@Chris

I backported your patches to secboot[1] and go-tpm2[2] which are currently used[3] by snapd.
With test image which includes your patches, I can install uc20 when the hash algorithm SM3 is enabled in BIOS.

But, the encrypted partition is still not created successfully because the test kernel snap is unsigned.
When I install uc20, I have to disable secure boot.

I'm trying to build a signed kernel snap and install uc20 with secure boot enabled.
I will keep you informed of the progress.
