From c9bd6f422090b874b5877b4cedcd7757eac33117 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 1 Sep 2016 15:28:01 -0700 Subject: rpmsg: Move endpoint related interface to rpmsg core Move the rpmsg_send() and rpmsg_destroy_ept() interface to the rpmsg core, so that we eventually can hide the rpmsg_endpoint ops from the public API.
