- plat_spmc_shmem_reclaim
SPMC provides platform hooks related to memory management interfaces.
-These hooks can be used for platform specific implementations like
-for managing access control, programming TZ Controller or MPUs.
-These hooks are called by SPMC before the initial share request completes,
-and after the final reclaim has been completed.
+These hooks can be used for platform specific implementations such as
+managing access control, programming TZ Controllers or MPUs, and
+validating ownership and security state of memory regions supplied
+through FFA_MEM_SHARE and FFA_MEM_LEND requests.
+
+Platform implementations are expected to ensure that memory regions
+accepted for sharing or lending comply with the platform security model
+and enforce any ownership, access control, and security-state checks
+required by the platform.
