From ee94cc6fa6dc11229a53c3b66d2ce3487bb3b08f Mon Sep 17 00:00:00 2001 From: Andrew Thoelke Date: Mon, 2 Jun 2014 12:38:12 +0100 Subject: Remove early_exceptions from BL3-1 The crash reporting support and early initialisation of the cpu_data allow the runtime_exception vectors to be used from the start in BL3-1, removing the need for the additional early_exception vectors and 2KB of code from BL3-1.
