+ * The CMT comes in 5 different identified flavours, depending not only on the
+ * SoC but also on the particular instance. The following table lists the main
+ * characteristics of those flavours.
+ *
+ *			16B	32B	32B-F	48B	48B-2
+ * -----------------------------------------------------------------------------
+ * Channels		2	1/4	1	6	2/8
+ * Control Width	16	16	16	16	32
+ * Counter Width	16	32	32	32/48	32/48
+ * Shared Start/Stop	Y	Y	Y	Y	N
+ *
+ * The 48-bit gen2 version has a per-channel start/stop register located in the
+ * channel registers block. All other versions have a shared start/stop register
+ * located in the global space.
+ *
+ * Channels are indexed from 0 to N-1 in the documentation. The channel index
+ * infers the start/stop bit position in the control register and the channel
+ * registers block address. Some CMT instances have a subset of channels
+ * available, in which case the index in the documentation doesn't match the
+ * "real" index as implemented in hardware. This is for instance the case with
+ * CMT0 on r8a7740, which is a 32-bit variant with a single channel numbered 0
+ * in the documentation but using start/stop bit 5 and having its registers
+ * block at 0x60.
+ *
+ * Similarly CMT0 on r8a73a4, r8a7790 and r8a7791, while implementing 32-bit
+ * channels only, is a 48-bit gen2 CMT with the 48-bit channels unavailable.

-TODO:
-- prepare private ieee80211 stack for merge with rtl8192su's version:
-  - add hwsec_active flag to struct ieee80211_device
-  - add bHwSec flag to cb_desc structure
-- switch to use shared "librtl" instead of private ieee80211 stack
-- switch to use LIB80211
-- switch to use MAC80211
-- use kernel coding style
-- checkpatch.pl fixes
-- sparse fixes
-- integrate with drivers/net/wireless/rtl818x

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames.  With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.

-- stop having thousands of lines of code duplicated with staging/rts_pstor

+**
+** Interface declarations and internal definitions for Skein hashing.
+**
+** Source code author: Doug Whiting, 2008.
+**
+** This algorithm and source code is released to the public domain.
+**
+***************************************************************************
+**
+** The following compile-time switches may be defined to control some
+** tradeoffs between speed, code size, error checking, and security.
+**
+** The "default" note explains what happens when the switch is not defined.
+**
+**  SKEIN_DEBUG            -- make callouts from inside Skein code
+**                            to examine/display intermediate values.
+**                            [default: no callouts (no overhead)]
+**
+**  SKEIN_ERR_CHECK        -- how error checking is handled inside Skein
+**                            code. If not defined, most error checking
+**                            is disabled (for performance). Otherwise,
+**                            the switch value is interpreted as:
+**                                0: use assert()      to flag errors
+**                                1: return SKEIN_FAIL to flag errors

+ * @file skein_api.h
+ * @brief A Skein API and its functions.
+ * @{
+ *
+ * This API and the functions that implement this API simplify the usage
+ * of Skein. The design and the way to use the functions follow the openSSL
+ * design but at the same time take care of some Skein specific behaviour
+ * and possibilities.
+ *
+ * The functions enable applications to create a normal Skein hashes and
+ * message authentication codes (MAC).
+ *
+ * Using these functions is simple and straight forward:
+ *
+ * @code
+ *
+ * #include "skein_api.h"
+ *
+ * ...
+ * struct skein_ctx ctx;             // a Skein hash or MAC context
+ *
+ * // prepare context, here for a Skein with a state size of 512 bits.
+ * skein_ctx_prepare(&ctx, SKEIN_512);
+ *
+ * // Initialize the context to set the requested hash length in bits
+ * // here request a output hash size of 31 bits (Skein supports variable
+ * // output sizes even very strange sizes)
+ * skein_init(&ctx, 31);
+ *
+ * // Now update Skein with any number of message bits. A function that
+ * // takes a number of bytes is also available.
+ * skein_update_bits(&ctx, message, msg_length);
+ *
+ * // Now get the result of the Skein hash. The output buffer must be
+ * // large enough to hold the request number of output bits. The application
+ * // may now extract the bits.
+ * skein_final(&ctx, result);
+ * ...
+ * @endcode
+ *
+ * An application may use @c skein_reset to reset a Skein context and use
+ * it for creation of another hash with the same Skein state size and output
+ * bit length. In this case the API implementation restores some internal
+ * internal state data and saves a full Skein initialization round.
+ *
+ * To create a MAC the application just uses @c skein_mac_init instead of
+ * @c skein_init. All other functions calls remain the same.

- * Description:
- *
- * NOTE.... Because CRCdwGetCrc32Ex() is an iteration function,
- *          this means we will use the output of CRCdwGetCrc32Ex()
- *          to be a new argument to do next CRCdwGetCrc32Ex() calculation.
- *          Thus, the final result must be inverted to be the
- *          correct answer.
- *
- * Parameters:
- *  In:
- *      pbyData     - the data stream
- *      cbByte      - the length of the stream
- *  Out:
- *      none
- *
- * Return Value: CRC-32

+ *

+ *
+ * MAX3421 is a chip implementing a USB 2.0 Full-/Low-Speed host
+ * controller on a SPI bus.
+ *
+ * Based on:
+ *	o MAX3421E datasheet
+ *		http://datasheets.maximintegrated.com/en/ds/MAX3421E.pdf
+ *	o MAX3421E Programming Guide
+ *		http://www.hdl.co.jp/ftpdata/utl-001/AN3785.pdf
+ *	o gadget/dummy_hcd.c
+ *		For USB HCD implementation.
+ *	o Arduino MAX3421 driver
+ *	     https://github.com/felis/USB_Host_Shield_2.0/blob/master/Usb.cpp
+ *
+ * This file is licenced under the GPL v2.
+ *
+ * Important note on worst-case (full-speed) packet size constraints
+ * (See USB 2.0 Section 5.6.3 and following):
+ *
+ *	- control:	  64 bytes
+ *	- isochronous:	1023 bytes
+ *	- interrupt:	  64 bytes
+ *	- bulk:		  64 bytes
+ *
+ * Since the MAX3421 FIFO size is 64 bytes, we do not have to work about
+ * multi-FIFO writes/reads for a single USB packet *except* for isochronous
+ * transfers.  We don't support isochronous transfers at this time, so we
+ * just assume that a USB packet always fits into a single FIFO buffer.
+ *
+ * NOTE: The June 2006 version of "MAX3421E Programming Guide"
+ * (AN3785) has conflicting info for the RCVDAVIRQ bit:
+ *
+ *	The description of RCVDAVIRQ says "The CPU *must* clear
+ *	this IRQ bit (by writing a 1 to it) before reading the
+ *	RCVFIFO data.
+ *
+ * However, the earlier section on "Programming BULK-IN
+ * Transfers" says * that:
+ *
+ *	After the CPU retrieves the data, it clears the
+ *	RCVDAVIRQ bit.
+ *
+ * The December 2006 version has been corrected and it consistently
+ * states the second behavior is the correct one.
+ *
+ * Synchronous SPI transactions sleep so we can't perform any such
+ * transactions while holding a spin-lock (and/or while interrupts are
+ * masked).  To achieve this, all SPI transactions are issued from a
+ * single thread (max3421_spi_thread).

-	---help---
-	  The frame buffer device provides an abstraction for the graphics
-	  hardware. It represents the frame buffer of some video hardware and
-	  allows application software to access the graphics hardware through
-	  a well-defined interface, so the software doesn't need to know
-	  anything about the low-level (hardware register) stuff.
-
-	  Frame buffer devices work identically across the different
-	  architectures supported by Linux and make the implementation of
-	  application programs easier and more portable; at this point, an X
-	  server exists which uses the frame buffer device exclusively.
-	  On several non-X86 architectures, the frame buffer device is the
-	  only way to use the graphics hardware.
-
-	  The device is accessed through special device nodes, usually located
-	  in the /dev directory, i.e. /dev/fb*.
-
-	  You need an utility program called fbset to make full use of frame
-	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-	  and the Framebuffer-HOWTO at
-	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
-	  information.
-
-	  Say Y here and to the driver for your graphics board below if you
-	  are compiling a kernel for a non-x86 architecture.
-
-	  If you are compiling for the x86 architecture, you can say Y if you
-	  want to play with it, but it is not essential. Please note that
-	  running graphical applications that directly touch the hardware
-	  (e.g. an accelerated X server) and that are not frame buffer
-	  device-aware may cause unexpected results. If unsure, say N.

-	  board. This means you cannot see any output sent to this frame
-	  buffer device, while it does consume precious memory. The main use
-	  of this frame buffer device is testing and debugging the frame
-	  buffer subsystem. Do NOT enable it for normal systems! To protect
-	  the innocent, it has to be enabled explicitly at boot time using the
-	  kernel option `video=vfb:'.
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called vfb. In order to load it, you must use
-	  the vfb_enable=1 option.
-
-	  If unsure, say N.

+	tristate "Support for frame buffer devices"
+	---help---
+	  The frame buffer device provides an abstraction for the graphics
+	  hardware. It represents the frame buffer of some video hardware and
+	  allows application software to access the graphics hardware through
+	  a well-defined interface, so the software doesn't need to know
+	  anything about the low-level (hardware register) stuff.
+
+	  Frame buffer devices work identically across the different
+	  architectures supported by Linux and make the implementation of
+	  application programs easier and more portable; at this point, an X
+	  server exists which uses the frame buffer device exclusively.
+	  On several non-X86 architectures, the frame buffer device is the
+	  only way to use the graphics hardware.
+
+	  The device is accessed through special device nodes, usually located
+	  in the /dev directory, i.e. /dev/fb*.
+
+	  You need an utility program called fbset to make full use of frame
+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
+	  and the Framebuffer-HOWTO at
+	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
+	  information.
+
+	  Say Y here and to the driver for your graphics board below if you
+	  are compiling a kernel for a non-x86 architecture.
+
+	  If you are compiling for the x86 architecture, you can say Y if you
+	  want to play with it, but it is not essential. Please note that
+	  running graphical applications that directly touch the hardware
+	  (e.g. an accelerated X server) and that are not frame buffer
+	  device-aware may cause unexpected results. If unsure, say N.

+	 transfers do not work for your driver and if you are using
+	 nvidiafb, i810fb or savagefb.
+
+	 In general, choosing Y for this option is safe.  If you
+	 experience extremely long delays while booting before you get
+	 something on your display, try setting this to N.  Matrox cards in

+	 the standard blitting divides the screen into pixels. Because the
+	 default drawing element is a tile, drawing functions will be passed
+	 parameters in terms of number of tiles instead of number of pixels.
+	 For example, to draw a single character, instead of using bitmaps,
+	 an index to an array of bitmaps will be used.  To clear or move a
+	 rectangular section of a screen, the rectangle will be described in
+	 terms of number of tiles in the x- and y-axis.
+
+	 This is particularly important to one driver, matroxfb.  If
+	 unsure, say N.
