wireless: mwifiex: initial commit for Marvell mwifiex driver

This driver adds WiFi support for Marvell 802.11n based chipsets
with SDIO interface. Currently only SD8787 is supported. More
chipsets will be supported later.

===============================================================================
U S E R M A N U A L
1) FOR DRIVER INSTALL
a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
create the directory if it doesn't exist.
b) Install WLAN driver,
insmod mwifiex.ko
c) Uninstall WLAN driver,
ifconfig mlanX down
rmmod mwifiex
2) FOR DRIVER CONFIGURATION AND INFO
The configurations can be done either using the 'iw' user space
utility or debugfs.
a) 'iw' utility commands
Following are some useful iw commands:-
iw dev mlan0 scan
This command will trigger a scan.
The command will then display the scan table entries
iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
The above command can be used to connect to an AP with a particular SSID.
Ap's operating frequency can be specified or even the bssid. If the AP is using
WEP encryption, wep keys can be specified in the command.
Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.
iw dev mlan0 disconnect
This command will be used to disconnect from an AP.
iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
The command will be used to join or create an ibss. Optionally, operating frequency,
bssid and the security related parameters can be specified while joining/creating
and ibss.
iw dev mlan0 ibss leave
The command will be used to leave an ibss network.
iw dev mlan0 link
The command will be used to get the connection status. The command will return parameters
such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.
Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.
b) Debugfs interface
The debugfs interface can be used for configurations and for getting
some useful information from the driver.
The section below explains the configurations that can be
done.
Mount debugfs to /debugfs mount point:
mkdir /debugfs
mount -t debugfs debugfs /debugfs
The information is provided in /debugfs/mwifiex/mlanX/:
iw reg set <country code>
The command will be used to change the regulatory domain.
iw reg get
The command will be used to get current regulatory domain.
info
This command is used to get driver info.
Usage:
cat info
driver_name = "mwifiex"
driver_version = <driver_name, driver_version, (firmware_version)>
interface_name = "mlanX"

cat regrdwr
where the parameters are,
<type>: 1:MAC/SOC, 2:BBP, 3:RF, 4:PMIC, 5:CAU
<offset>: offset of register
[value]: value to be written
Examples:
echo "1 0xa060" > regrdwr : Read the MAC register
echo "1 0xa060 0x12" > regrdwr : Write the MAC register
echo "1 0xa794 0x80000000" > regrdwr
: Write 0x80000000 to MAC register
rdeeprom
This command is used to read the EEPROM contents of the card.
Usage:
echo "<offset> <length>" > rdeeprom
cat rdeeprom
where the parameters are,
<offset>: multiples of 4
<length>: 4-20, multiples of 4
Example:
echo "0 20" > rdeeprom : Read 20 bytes of EEPROM data from offset 0
getlog
This command is used to get the statistics available in the station.
