powerpc/mpc85xx: Add workaround for erratum A-005125
In a very rare condition, a system hang is possible when the e500 core initiates a guarded load to PCI / PCIe /SRIO performs a coherent write to memory. Please refer to errata document for more details. This erratum applies to the following SoCs and their variants, if any. BSC9132 BSC9131 MPC8536 MPC8544 MPC8548 MPC8569 MPC8572 P1010 P1020 P1021 P1022 P1023 P2020 C29x Signed-off-by: York Sun <yorksun@freescale.com> CC: Scott Wood <scottwood@freescale.com>
