Wlan works on A910

[Antonio Ospite]

Hi list,

Since revision 2109 openezx patchset[0] offers partial support for the
Marvell Libertas 8385 SDIO Wlan card found in Motorola A910.

I made some rough tests: I can associate to my AP using WPA-PSK with
wpa_supplicant, and ssh works fine. I did not test power consumption,
nor other association schemes.

Checkout the code and use the supplied defconfig-a910 (which uses
nfsroot). A binary firmware is needed, it comes with the 2.4 code,
the required files are:
./drivers/net/wireless/8385/if/if_sdio/helper_sd.bin
./drivers/net/wireless/8385/if/if_sdio/sd8385.bin

Put them in /lib/firmware in your rootfs and rename (or link) the helper
binary to sd8385_helper.bin

Layout of /lib/firmware must be as follows:
/lib/firmware/sd8385.bin
/lib/firmware/sd8385_helper.bin

There are also other firmwares available on the web [1] and [2], but
I don't know what difference they have.

That's all for now, in original code there were some workarounds to
prevent power leaking, but I haven't understood them and hence you find
them commented in openezx code.

Bye,
   Antonio
