From 90b3a6acb50a0361698c3674d487335f6abb91b8 Mon Sep 17 00:00:00 2001 From: Dan Handley Date: Mon, 27 Apr 2015 11:49:22 +0100 Subject: Add linker symbol declarations to bl_common.h Add extern declarations of linker symbols to bl_common.h. These are used by platform ports to determine the memory layout of BL images. Adding the declarations to this file facilitates removal of these declarations from the platform porting source files in subsequent patches. Also remove the linker symbol declarations from common TSP source code.
