I attached my patchset here. It is based on diffing the gateworks 2.6.x to 2.6.18 and some cleanup. It is setup so
that the board type should be CONFIG_ARCH_IXDP425 and not AVILA as the gateworks documentation mentions: "Do NOT choose
Avila as a supported platform. You MUST select IXDP425 as the platform. Currently RedBoot does not pass the Gateworks
Avila Machine Id (526) to Linux but rather passes the IXDP425 Machine Id (245). At some point within the next BSP
release or two we will change RedBoot to pass 526 to Linux at which time Linux will need to be configured as Avila."
See RedBoot's packages/hal/arm/xscale/ixdp425/current/cdl/hal_arm_xscale_ixdp425.cdl for the file. I have not tried a
patch to this but it looks pretty simple.
This patchset can be applied to 2.6.18.4 and perhaps other versions. It does not include the ethernet driver. It is
big endian mode. Some sites, like the nslu2 folks have little endian versions as well.
By the way, you will need to manually set the firmware and MAC addresses of the ethernet ports with my patchset. See
Documentation/networking/ixp4xx/README . I handle it using option 2 in the README and then using the following code:
modprobe ixp4xx_npe
cat /etc/IxNpeMicrocode.dat > /dev/ixp4xx_ucode
modprobe ixp4xx_qmgr
modprobe ixp4xx_mac
# The addresses live in the first 12 bytes of eeprom.
# We use hexdump to format them in hex with colons separating the bytes.
macs=`hexdump -v -n 12 -e "1/1 \"%.2X:\"" /sys/class/i2c-dev/i2c-0/device/0-0051/eeprom`
mac0=${macs:0:17}
mac1=${macs:18:17}
ifconfig eth0 hw ether ${mac0}
ifconfig eth1 hw ether ${mac1}
Also, see http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2006-December/037662.html
on the arm kernel mailing list. It looks like 2.6.20 will support avila nicely, even with the new libata driver.
Does anyone know when the GPL ethernet driver is going to be submitted to the netdev list? I have not seen it go
through there. It did appear on the debian kernel list but it really needs to go through netdev to get into the main line.
-Ack
