Subject: [PATCH 1/3] edac: Use ccsr_pci structure instead of hardcoded define
Date: Fri, 5 Nov 2010 10:54:51 +0800	[thread overview]
Message-ID: <1288925691-1217-1-git-send-email-b25806@freescale.com> (raw)

There are some differences of register offset and definition between
pci and pcie error management registers. While, some other pci/pcie
error management registers are nearly the same.

To merge pci and pcie edac code into one, it is easier to use ccsr_pci
structure than the hardcoded define. So remove the hardcoded define and
add pci/pcie error management register in ccsr_pci structure.
