if ETRAX_ARCH_V32
config ETRAX_ETHERNET
bool "Ethernet support"
depends on ETRAX_ARCH_V32 && NETDEVICES
select MII
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
select SERIAL_CORE_CONSOLE
help
Enables the ETRAX FS serial driver for ser0 (ttyS0)
You probably want this enabled.
config ETRAX_RS485

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. 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).
config ETRAX_SERIAL_PORT2
bool "Serial port 2 enabled"
depends on ETRAXFS_SERIAL
help
Enables the ETRAX FS serial driver for ser2 (ttyS2).

help
Enables the ETRAX FS serial driver for ser3 (ttyS3).
config ETRAX_SYNCHRONOUS_SERIAL
bool "Synchronous serial-port support"
depends on ETRAX_ARCH_V32
help
Enables the ETRAX FS synchronous serial driver.
config ETRAX_SYNCHRONOUS_SERIAL_PORT0
bool "Synchronous serial port 0 enabled"
depends on ETRAX_SYNCHRONOUS_SERIAL
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.
config ETRAX_SYNCHRONOUS_SERIAL_PORT1
bool "Synchronous serial port 1 enabled"
depends on ETRAX_SYNCHRONOUS_SERIAL && ETRAXFS
help
Enabled synchronous serial port 1.
config ETRAX_SYNCHRONOUS_SERIAL1_DMA
bool "Enable DMA on synchronous serial port 1."
depends on ETRAX_SYNCHRONOUS_SERIAL_PORT1
help
A synchronous serial port can run in manual or DMA mode.
Selecting this option will make it run in DMA mode.
config ETRAX_AXISFLASHMAP
bool "Axis flash-map support"
depends on ETRAX_ARCH_V32
select MTD
select MTD_CFI
select MTD_CFI_AMDSTD
select MTD_JEDECPROBE
select MTD_BLOCK
select MTD_COMPLEX_MAPPINGS
select MTD_MTDRAM
help
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
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.
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
bool "Cardbus support"
depends on ETRAX_ARCH_V32
help
Enabled the ETRAX Cardbus driver.
config PCI
bool

select FW_LOADER
help
Enables IO-processor hotplug firmware loading support.
config ETRAX_STREAMCOPROC
tristate "Stream co-processor driver enabled"
depends on ETRAX_ARCH_V32
help
This option enables a driver for the stream co-processor
for cryptographic operations.
config ETRAX_MMC_IOP
tristate "MMC/SD host driver using IO-processor"
depends on ETRAX_ARCH_V32 && MMC
help
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.
config ETRAX_SPI_MMC
# Make this one of several "choices" (possible simultaneously but
# suggested uniquely) when an IOP driver emerges for "real" MMC/SD
# protocol support.
tristate
depends on !ETRAX_MMC_IOP
default MMC
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
select SPI_BITBANG
help
This enables using an synchronous serial (sser) port as a
SPI master controller on Axis ETRAX FS and later. The
driver can be configured to use any sser port.
config SPI_ETRAX_GPIO
tristate
depends on SPI_MASTER && ETRAX_ARCH_V32
select SPI_BITBANG
help
This enables using GPIO pins port as a SPI master controller
on Axis ETRAX FS and later. The driver can be configured to
use any GPIO pins.

depends on ETRAX_SPI_MMC
default m if MMC_SPI=m
default y if MMC_SPI=y
default y if MMC_SPI=n
select SPI_ETRAX_SSER
help
Say Y for an MMC/SD socket connected to synchronous serial port 0,
or for devices using the SPI protocol on that port. Say m if you
want to build it as a module, which will be named spi_crisv32_sser.
(You need to select MMC separately.)
config ETRAX_SPI_SSER1

Say Y for an MMC/SD socket connected to general I/O pins (but not
a complete synchronous serial ports), or for devices using the SPI
protocol on general I/O pins. Slow and slows down the system.
Say m to build it as a module, which will be called spi_crisv32_gpio.
