From 1a9519373b977ef3f7c9563ad3acb6c6f2424657 Mon Sep 17 00:00:00 2001 From: Richard Retanubun Date: Wed, 1 Jul 2009 14:03:15 -0400 Subject: [PATCH] Assigned a static SMI address to all UECs TBIPA address. It is set to 0x1F by default and can be overwritten on the board header file by defining CONFIG_UTBIPAR_INIT_TBIPA. This allows the CPU to simply "reserve" one SMI address instead of using a different one for each UEC.
