it's always good to add more test, but we should put test code to

Review Comment:
I take it you mean to remove `CONFIG_DEV_OPTEE_SMC64_TEST` entirely. No
problem (I just thought since I wrote it, why not make it available for anyone
else, but I will remove it).
Though I must admit, I didn't get why it "isn't good". Code quality or just
the fact that test code exists there?

Review Comment:
Not really, the point of this was/is to test through kernel thread context,
or otherwise without bringing up any apps/userspace.
Btw I see you marked the block containing also the compatibility checks.
Perhaps by accident? The compatibility checks I think are even more so needed
there to avoid registering the driver altogether.

since SMC also support for arm32, could we remove 64 or add both 32 and 64?
