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"

+		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.
+	Usage:
+
+	cat getlog
