H A D | fsl_pci.h | diff 4e0e3435b50285eafe5898124ce02f7577f6803a Sun Apr 28 07:20:08 CEST 2013 Hongtao Jia <hongtao.jia@freescale.com> powerpc/85xx: Add machine check handler to fix PCIe erratum on mpc85xx
A PCIe erratum of mpc85xx may causes a core hang when a link of PCIe goes down. when the link goes down, Non-posted transactions issued via the ATMU requiring completion result in an instruction stall. At the same time a machine-check exception is generated to the core to allow further processing by the handler. We implements the handler which skips the instruction caused the stall.
This patch depends on patch: powerpc/85xx: Add platform_device declaration to fsl_pci.h
