Resend this patch again. This patch renames the duplicated function name to fix it. The SecPeiDebugAgentLib uses the global variable mMemoryDiscoveredNotifyList for a PPI notification on the Memory Discovered PPI. This same variable name is used in the DxeIplPeim for the same PPI notification. The XCODE5 tool chain detects this duplicate symbol when the OVMF platform is built with the flag -D SOURCE_DEBUG_ENABLE. The fix is to rename this global variable in the SecPeiDebugAgentLib library.
