From d094fb8084aedd9e0458bd2618b8e0c555203744 Mon Sep 17 00:00:00 2001 From: Loic Pallardy Date: Thu, 31 Jan 2013 17:55:25 +0100 Subject: [PATCH] mailbox: rename omap_mbox in mailbox In order to create a generic mailbox framework, functions and structures should be renamed in mailbox. Taking care of remoteproc and tidspbridge while at it.
