Igor Opaniuk 8b1312662b tee: change return code for REE FS supplicant cmd ... If OP-TEE core is compiled with support of REE FS and RPMB at the same time (CFG_RPMB_FS ?= y; CFG_RPMB_FS ?= y), and persistent storage API is used with TEE_STORAGE_PRIVATE storage id, it will lead to TA panic. E/TC:? 0 TA panicked with code 0xffff0009 ..... E/TC:? 0 Call stack: E/TC:? 0 0x000000004002f2f8 TEE_OpenPersistentObject at lib/libutee/tee_api_objects.c:422 In this particular case TEE_ERROR_STORAGE_NOT_AVAILABLE is more suitable than TEE_ERROR_NOT_IMPLEMENTED, as it provides to a TA a possibility to handle this error code [1]. >From GPD TEE Internal Core specification [2]: TEE_ERROR_STORAGE_NOT_AVAILABLE - if the persistent object is stored in a storage area which is currently inaccessible. It may be associated with the device but unplugged, busy, or inaccessible for some other reason.
