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 NET_ETHERNET help Allocate large buffers for MPC8xx Etherenet. Increases throughput and decreases the likelihood of dropped packets, but costs memory. config SMC2_UART bool "Use SMC2 for UART" help If you would like to use SMC2 as a serial port, say Y here. If in doubt, say Y here. config ALTSMC2 bool "Use Alternate SMC2 I/O (823/850)" depends on SMC2_UART help If you have an MPC823 or MPC850 and would like to use the alternate SMC2 for I/O, say Y here. If in doubt, say N here. config CONS_SMC2 bool "Use SMC2 for Console" depends on SMC2_UART help If you are going to have a serial console on your device and are using SMC2 for your serial port, say Y here, else say N. config USE_SCC_IO bool "Enable SCC2 and SCC3 for UART" help If your MPC8xx board has other SCC ports that you would like to use for for a serial port, say Y here. If in doubt, say N here. config HTDMSOUND bool "Embedded Planet HIOX Audio" depends on SOUND=y # 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. If in doubt, say N here. config UCODE_PATCH bool "I2C/SPI Microcode Patch" help Motorola releases microcode updates for their 8xx CPM modules. The microcode update file has updates for IIC, SMC and USB. Currently only the USB update is available by default, if the MPC8xx USB option is enabled. If in doubt, say 'N' here. endmenu |
