The GuruPlug Server Plus incorporates an AzureWave AW-GH381 IEEE 802.11 b/g Wireless LAN & Bluetooth 3.0 module IC, functionally equivalent to the Marvell 88W8688
Enable the following as kernel modules and compile your modules:
Device Drivers > Network device support > Wireless LAN Marvell 8xxx Libertas WLAN driver support Marvell Libertas 8385/8686/8688 SDIO 802.11b/g cards
The modules above will want to load firmware from the root filesystem that is not available until the filesystem is mounted. This will result in an initial error loading firmware (see below), but the kernel will retry later and should succeed. To mitigate this issue, I choose to compile these as loadable modules rather than built-in.

Download Binary BLOBs to /lib/firmware:
mkdir /lib/firmware cd /lib/firmware wget http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8688_helper.bin wget http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8688.bin
And reboot. The modules should now load. If not, manually load them using:
insmod /lib/modules/<kernel ver>/kernel/drivers/net/wireless/libertas/libertas.ko insmod /lib/modules/<kernel ver>/kernel/drivers/net/wireless/libertas/libertas_sdio.ko
When loaded, the following debug messages should be displayed:
libertas_sdio mmc0:0001:1 (unregistered net_device): 00:24:23:1f:b3:e9, fw 10.38.1p25, cap 0x00000303 libertas_sdio mmc0:0001:1 wlan0: Marvell WLAN 802.11 adapter
Enable the following Linux kernel modules and recompile your kernel. These modules will want to load firmware from the root filesystem that is not available until mounted. This will result in an initial error loading firmware, but the kernel will retry later and should succeed. To mitigate this issue, I choose to compile these as loadable modules rather than built-in.

The WLAN/Bluetooth SoC has an ARMv5TE core that runs closed firmware. Download the Binary BLOBs (firmware) to /lib/firmware/mrvl/:
mkdir /lib/firmware /lib/firmware/mrvl cd /lib/firmware/mrvl wget http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8688_helper.bin wget http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8688.bin
Upon reboot, you should now see the following kernel message as the module loads:
Bluetooth: vendor=0x2df, device=0x9105, class=255, fn=2
and be greeted with a Bluetooth hci device:

If this is not the case, check that the btmrvl.ko & btmrvl_sdio.ko modules are loaded.
