I haven't yet got QEMU environment working with aarch64, this produces just a blank screen:
./output/host/usr/bin/qemu-system-aarch64 -M virt -cpu cortex-a53 -smp 1 -kernel output/images/Image -initrd output/images/rootfs.cpio -serial stdio
My BuildRoot fork for TPM and keyring testing is located over here:
The "ARM version" is at this point in aarch64 branch. Over time I will define tpmdd-x86_64 and tpmdd-aarch64 boards and everything will be then in the master branch.
To create identical images you just need to
$ make tpmdd_defconfig && make
Can you check if you see anything obviously wrong? I'm eager to test this patch set, and in bigger picture I really need to have ready to run aarch64 environment available.
I would rather suggest you to follow steps listed here  as to test this feature on Qemu aarch64 we need to build firmwares such as TF-A, OP-TEE, UEFI etc. which are all integrated into OP-TEE Qemu build system . And then it would be easier to migrate them to your buildroot environment as well.

Can you provide 'keyctl_change'? Otherwise, the steps are easy to follow.

After I've successfully tested 2/4, I'd suggest that you roll out one more version and CC the documentation patch to Elaine and Mini, and clearly remark in the commit message that TEE is a standard, with a link to the specification.
Sure, I will roll out the next version after your testing.
Thanks, I'll try this at instant, and give my feedback.
I bump into this:

Could you check if the following directory tree is built after executing the below command?
