Say N here if unsure or if you don't need link status reports. config FEC_AM79C874 bool "Support AMD79C874 PHY" depends on USE_MDIO config FEC_LXT970 bool "Support LXT970 PHY" depends on USE_MDIO config FEC_LXT971 bool "Support LXT971 PHY" depends on USE_MDIO config FEC_QS6612 bool "Support QS6612 PHY" depends on USE_MDIO config ENET_BIG_BUFFERS bool "Use Big CPM Ethernet Buffers" depends on SCC_ENET || FEC_ENET help Allocate large buffers for MPC8xx Ethernet. Increases throughput and decreases the likelihood of dropped packets, but costs memory. # This doesn't really belong here, but it is convenient to ask # 8xx specific questions. comment "Generic MPC8xx Options" config 8xx_COPYBACK bool "Copy-Back Data Cache (else Writethrough)" help Saying Y here will cause the cache on an MPC8xx processor to be used in Copy-Back mode. If you say N here, it is used in Writethrough mode. If in doubt, say Y here. config 8xx_CPU6 bool "CPU6 Silicon Errata (860 Pre Rev. C)" help MPC860 CPUs, prior to Rev C have some bugs in the silicon, which require workarounds for Linux (and most other OSes to work). If you get a BUG() very early in boot, this might fix the problem. For more details read the document entitled "MPC860 Family Device Errata Reference" on Motorola's website. This option also incurs a performance hit.
