ns_agent_mailbox_entry is the entry of ns agent mailbox partition. It is assigned to the entry of the corresponding thread at https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/secure_fw/s.... When the ns agent mailbox thread starts, this function is called.

Thanks for the reply.
I'll try to explain it in more detail.
I checked that the auto-generated load_info_ns_agent_mailobx.c contains the struct partition_tfm_ns_mailbox_agent_load_info_t tfm_ns_mailbox_agent_load and the corresponding struct ns_agent_mailbox_entry.
We also checked that the tfm_s binary image contains tfm_ns_mailbox_agent_load.
However, when I debug tfm_s using trace32, I can't find the point where ns_agent_mailbox_entry is called.
I'm wondering if there is a TFM component I'm missing or something I can refer to.
