AM625: optee incompatibility between 10.00.07 and 11.02.08

Part Number: AM625

I've been running a yocto build based on 10.00.07.  I'm not testing an upgrade to 11.02.08.

Attempts to use optee (TEEC_OpenSession) are failing with the following errors:

E/LD:  init_elf:493 sys_open_ta_bin(56dd8bf2-3c65-413e-b494-da845ed2f102)
E/TC:? 0 ldelf_init_with_ldelf:152 ldelf failed with res: 0xffff000f

TEEC_OpenSession() returns 0xffff000f, with origin parameter equaling 3.

How can I recover use of my device's secure store after the upgrade from 10.00.07 to 11.02.08?
