From 181a3650113883728927928b3ac81ad6dade4b2c Mon Sep 17 00:00:00 2001 From: Haiying Wang <Haiying.Wang@freescale.com> Date: Wed, 3 Dec 2008 10:08:19 -0500 Subject: [PATCH] Set IVPR to kenrel entry point in second core boot page Assuming the OSes exception vectors start from the base of kernel address, and the kernel physical starting address can be relocated to an non-zero address. This patch enables the second core to have a valid IVPR for debugger before kernel setting IVPR in CAMP mode. Otherwise, IVPR is 0x0 and it is not a valid value for second core which runs kernel at different physical address other than 0x0.
