Hi Julian,

With this change, is QCOM_TZMEM_MODE_SHMBRIDGE still needed?

I think QCOM_TZMEM_MODE_SHMBRIDGE can therefore be removed entirely, along with the conditional declarations and stubs in qcom_tzmem.h and the corresponding select in the qcomtee Kconfig.

Looking at it again, I see that the patch does not actually do what I had expected. As you say the option no longer has any effect at all, when I thought the tzmem driver would just default back to generic mode without shmbridge being enabled.

What we probably want here is to change it to

#ifndef CONFIG_QCOM_TZMEM_MODE_SHMBRIDGE ... #else ... #endif

to keep the behavior unchanged and just fix the Kconfig logic.
