help
This option enables the ETRAX FS built-in 10/100Mbit Ethernet
controller.
config ETRAX_NO_PHY
bool "PHY not present"
depends on ETRAX_ETHERNET
help
This option disables all MDIO communication with an ethernet
transceiver connected to the MII interface. 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

Enables the ETRAX FS serial driver for ser0 (ttyS0)
You probably want this enabled.

help
Enables support for RS-485 serial communication.
config ETRAX_RS485_DISABLE_RECEIVER
bool "Disable serial receiver"
depends on ETRAX_RS485

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. You can control what DMA channels to use
if you do not need DMA to something else.
ser0 can use dma4 or dma6 for output and dma5 or dma7 for input.
config ETRAX_SERIAL_PORT1
bool "Serial port 1 enabled"
depends on ETRAXFS_SERIAL
help
Enables the ETRAX FS serial driver for ser1 (ttyS1).

help
Enabled synchronous serial port 0.
config ETRAX_SYNCHRONOUS_SERIAL0_DMA
bool "Enable DMA on synchronous serial port 0."
depends on ETRAX_SYNCHRONOUS_SERIAL_PORT0
help
A synchronous serial port can run in manual or DMA mode.
Selecting this option will make it run in DMA mode.

help
Enabled synchronous serial port 1.

This option enables MTD mapping of flash devices. 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

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.
Say Y if your boot code, kernel and root file system is in
NAND flash. Say N if they are in NOR flash.
config ETRAX_CARDBUS

This option enables the SD/MMC host controller interface.
The host controller is implemented using the built in
IO-Processor. Only the SPU is used in this implementation.

select SPI
select MMC_SPI
# While the board info is MMC_SPI only, the drivers are written to be
# independent of MMC_SPI, so we'll keep SPI non-dependent on the
# MMC_SPI config choices (well, except for a single depends-on-line
# for the board-info file until a separate non-MMC SPI board file
# emerges).
# FIXME: When that happens, we'll need to be able to ask for and
# configure non-MMC SPI ports together with MMC_SPI ports (if multiple
# SPI ports are enabled).
config SPI_ETRAX_SSER
tristate
depends on SPI_MASTER && ETRAX_ARCH_V32

Say Y for an MMC/SD socket connected to synchronous serial port 0,
