From 092396fa161036fc9754296269c510e76910c756 Mon Sep 17 00:00:00 2001 From: Richard Retanubun RichardRetanubun@RuggedCom.com Date: Tue, 2 Jun 2009 11:31:05 -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. --- drivers/qe/uec.c | 17 +++++++++-------- 1 files changed, 9 insertions(+), 8 deletions(-)
