Firmware problems with Lesswire Wibear 11n module using mwifiex

[Martin Fuzzey <mfuzzey@parkeon.com>]

Hi all,

I have a Lesswire Wibear 11n combined wifi / bluetooth module with SDIO 
interface.
This has a Marvell 8787 chipset and is recognized by the mainline 
(3.9-rc4) kernel.

It detects the module and asks for the  sd8787_uapsta.bin firmware.

I got that from the Marvell git repo at 
git://git.marvell.com/mwifiex-firmware.git
Using this latest commit:

commit dd7193bc187a5182a6236cb6337699d2229c54b0

     linux-firmware: update Marvell SD8787 firmware image

     Version 14.66.9.p96

The firmware is loaded OK but then a timeout occurs on the first command 
sent to the module.

Here are the logs on module insertion (with a few extra logs of my own 
@MF@ added):

This shows that there is no reply to the first command sent in 
mwifiex_sta_init_cmd()

         ret = mwifiex_send_cmd_sync(priv, HostCmd_CMD_FUNC_INIT,
                         HostCmd_ACT_GEN_SET, 0, NULL);
         if (ret) {
             dev_info(priv->adapter->dev, "@MF@ mwifiex_send_cmd_sync B 
failed %d\n", ret);
             return -1;
         }

I've also tried the other two versions (14.66.9.p80 and 14.57.5.p44) int 
the git repo mentionned above with the same results

Any ideas?
