From 68e4e76af55746a4330865f56476e58ce4140ca8 Mon Sep 17 00:00:00 2001 From: TsiChung Liew Date: Thu, 11 Mar 2010 15:04:21 -0600 Subject: ColdFire: Relocate vector table - mcf5445x Newer ColdFire processors family boot from address 0 instead of 0xFFnn_nnnn. When the boot flash base chip select is set at new location instead of 0, an un-predictable error will occur if there is an vector being trigger and refer it to an invalid address or the vector table handler is not existed at address 0.
