Subject: [U-Boot] [PATCH] mpc7448hpc2: Fix PCI I/O space mapping.
Date: Wed, 13 Aug 2008 11:44:57 -0700 [thread overview]
Message-ID: <48A32BA9.9070004@mvista.com> (raw)
PCI I/O space is currently mapped 1:1 at 0xFA000000. Linux requires
PCI I/O space to start at 0 on the PCI bus. This patch maps PCI I/O
space such that 0xFA000000 in the processor's address space maps to 0
on the PCI I/O bus.
