Motorola A910 has a Marvell Libertas 8385 SDIO WLAN adapter.
Only some rough tests has been made: we can associate to an AP using WPA-PSK with wpa_supplicant, and ssh works fine. Power consumption, and other association schemes, have not been tested.
How to use it
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:
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:
In original code there were some workarounds to prevent power leakage, but I haven't understood them and hence you find them commented in openezx code. (ao2)
