Yeah, I think so. Actually, I wasn't aware of Matthew's efforts, as it
didn't appear on linux-efi mailing list. (On bad, I haven't checked

At this point, I think it makes more sense to limit this patchset to
5/5 patch, which makes TPM event log initialized on ARM platforms.
Patches 1-4 introduce nothing more than Matthew already did, maybe
except putting calc_tpm2_event_size to a library instead of making it
inline. This function has already grown a bit so it may be a better
approach, but that's nothing to affect functionality.

I'll pull Matthew changes to my tree to confirm operation on ARM
platforms, if that works fine the only thing to merge would be 5/5 +
optionally the library change, if we reach agreement on that.
