+Subject: [PATCH 31/32] ANDROID: trusty: Make trusty transports configurable
+
+With TRUSTY_SMC_TRANSPORT set to 'y', SMC based message passing and
+memory sharing support will be compiled in to trusty core.
+
+With TRUSTY_FFA_TRANSPORT set to 'y', FFA based message passing and
+memory sharing support will be compiled in to trusty core. This
+depends on ARM FF-A driver (ARM_FFA_TRANSPORT).
+
+Enabling any of the transport sets config TRUSTY_HAVE_TRANSPORT to 'y'.
+Not enabling any of the transport causes the build to break.
