This option shall typically be enabled if the MII interface is connected to a switch. This option should normally be disabled. If enabled, speed and duplex will be locked to 100 Mbit and full duplex. config ETRAXFS_SERIAL bool "Serial-port support" depends on ETRAX_ARCH_V32 select SERIAL_CORE select SERIAL_CORE_CONSOLE help Enables the ETRAX FS serial driver for ser0 (ttyS0) You probably want this enabled. config ETRAX_RS485 bool "RS-485 support" depends on ETRAXFS_SERIAL help Enables support for RS-485 serial communication. config ETRAX_RS485_DISABLE_RECEIVER bool "Disable serial receiver" depends on ETRAX_RS485 help It is necessary to disable the serial receiver to avoid serial loopback. Not all products are able to do this in software only. config ETRAX_SERIAL_PORT0 bool "Serial port 0 enabled" depends on ETRAXFS_SERIAL help Enables the ETRAX FS serial driver for ser0 (ttyS0) Normally you want this on.

Needed to use flash memories. If unsure, say Y. config ETRAX_AXISFLASHMAP_MTD0WHOLE bool "MTD0 is whole boot flash device" depends on ETRAX_AXISFLASHMAP help When this option is not set, mtd0 refers to the first partition on the boot flash device. When set, mtd0 refers to the whole device, with mtd1 referring to the first partition etc. config ETRAX_PTABLE_SECTOR int "Byte-offset of partition table sector" depends on ETRAX_AXISFLASHMAP default "65536" help Byte-offset of the partition table in the first flash chip. The default value is 64kB and should not be changed unless you know exactly what you are doing. The only valid reason for changing this is when the flash block size is bigger than 64kB (e.g. when using two parallel 16 bit flashes). config ETRAX_NANDFLASH bool "NAND flash support" depends on ETRAX_ARCH_V32 select MTD_NAND select MTD_NAND_IDS help This option enables MTD mapping of NAND flash devices. Needed to use NAND flash memories. If unsure, say Y. config ETRAX_NANDBOOT bool "Boot from NAND flash" depends on ETRAX_NANDFLASH help This options enables booting from NAND flash devices.

The host controller is implemented using the built in IO-Processor.
