From e4879afba376dc6dcc2085760c614d615a203f73 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Wed, 15 Aug 2012 04:12:43 +0000 Subject: [PATCH] powerpc/mpc85xx:Enable debugger support to missed e500v2 SoC Freescale's e500v1 and e500v2 cores (used in mpc85xx chips) have some restrictions on external debugging (JTAG). Need to define define CONFIG_SYS_PPC_E500_DEBUG_TLB to enable a temporary TLB entry to be used during boot to work around the limitations. Enable missed e500v2 SoC i.e. MPC8536, MPC8544, MPC8548 and MPC8572 for debug support.
