This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Lowest risk for other platform. [Bug Description] this patch gets tpm eventlog information such as device boot status,event guid and so on, which will be from bios stage. it use "efi_retrieve_tpm2_eventlog" functions to get it for ARM64 platorm.
