-+Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
-+however from programming point of view there is nothing AMBA specific we use.
-+
-+Standard AMBA drivers are platform specific, have hardcoded addresses and use
-+AMBA standard fields like CID and PID.
-+
-+In case of Broadcom's cards every device consists of:
-+1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
-+   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
-+2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
-+   and PIDs (0x103BB369), but we do not use that info for anything. One of that
-+   devices is used for managing Broadcom specific core.
-+
-+Addresses of AMBA devices are not hardcoded in driver and have to be read from
-+EPROM.
-+
-+In this situation we decided to introduce separated bus. It can contain up to
-+16 devices identified by Broadcom specific fields: manufacturer, id, revision
-+and class.

-+Overlay Filesystem
-+==================
-+
-+This document describes a prototype for a new approach to providing
-+overlay-filesystem functionality in Linux (sometimes referred to as
-+union-filesystems).  An overlay-filesystem tries to present a
-+filesystem which is the result over overlaying one filesystem on top
-+of the other.
-+
-+The result will inevitably fail to look exactly like a normal
-+filesystem for various technical reasons.  The expectation is that
-+many use cases will be able to ignore these differences.
-+
-+This approach is 'hybrid' because the objects that appear in the
-+filesystem do not all appear to belong to that filesystem.  In many
-+cases an object accessed in the union will be indistinguishable
-+from accessing the corresponding object from the original filesystem.
-+This is most obvious from the 'st_dev' field returned by stat(2).
-+
-+While directories will report an st_dev from the overlay-filesystem,
-+all non-directory objects will report an st_dev from the lower or
-+upper filesystem that is providing the object.  Similarly st_ino will
-+only be unique when combined with st_dev, and both of these can change
-+over the lifetime of a non-directory object.  Many applications and
-+tools ignore these values and will not be affected.
-+
-+Upper and Lower
-+---------------
-+
-+An overlay filesystem combines two filesystems - an 'upper' filesystem
-+and a 'lower' filesystem.  When a name exists in both filesystems, the
-+object in the 'upper' filesystem is visible while the object in the
-+'lower' filesystem is either hidden or, in the case of directories,
-+merged with the 'upper' object.
-+
-+It would be more correct to refer to an upper and lower 'directory
-+tree' rather than 'filesystem' as it is quite possible for both
-+directory trees to be in the same filesystem and there is no
-+requirement that the root of a filesystem be given for either upper or
-+lower.
-+
-+The lower filesystem can be any filesystem supported by Linux and does
-+not need to be writable.  The lower filesystem can even be another
-+overlayfs.  The upper filesystem will normally be writable and if it
-+is it must support the creation of trusted.* extended attributes, and
-+must provide valid d_type in readdir responses, at least for symbolic
-+links - so NFS is not suitable.
-+
-+A read-only overlay of two read-only filesystems may use any
-+filesystem type.
-+
-+Directories
-+-----------
-+
-+Overlaying mainly involved directories.  If a given name appears in both
-+upper and lower filesystems and refers to a non-directory in either,
-+then the lower object is hidden - the name refers only to the upper
-+object.
-+
-+Where both upper and lower objects are directories, a merged directory
-+is formed.
-+
-+At mount time, the two directories given as mount options are combined
-+into a merged directory:
-+
-+  mount -t overlayfs overlayfs -olowerdir=/lower,upperdir=/upper /overlay
-+
-+Then whenever a lookup is requested in such a merged directory, the
-+lookup is performed in each actual directory and the combined result
-+is cached in the dentry belonging to the overlay filesystem.  If both
-+actual lookups find directories, both are stored and a merged
-+directory is created, otherwise only one is stored: the upper if it
-+exists, else the lower.
-+
-+Only the lists of names from directories are merged.  Other content
-+such as metadata and extended attributes are reported for the upper
-+directory only.  These attributes of the lower directory are hidden.
-+
-+whiteouts and opaque directories
-+--------------------------------
-+
-+In order to support rm and rmdir without changing the lower
-+filesystem, an overlay filesystem needs to record in the upper filesystem
-+that files have been removed.  This is done using whiteouts and opaque
-+directories (non-directories are always opaque).
-+
-+The overlay filesystem uses extended attributes with a
-+"trusted.overlay."  prefix to record these details.
-+
-+A whiteout is created as a symbolic link with target
-+"(overlay-whiteout)" and with xattr "trusted.overlay.whiteout" set to "y".
-+When a whiteout is found in the upper level of a merged directory, any
-+matching name in the lower level is ignored, and the whiteout itself
-+is also hidden.
-+
-+A directory is made opaque by setting the xattr "trusted.overlay.opaque"
-+to "y".  Where the upper filesystem contains an opaque directory, any
-+directory in the lower filesystem with the same name is ignored.
-+
-+readdir
-+-------
-+
-+When a 'readdir' request is made on a merged directory, the upper and
-+lower directories are each read and the name lists merged in the
-+obvious way (upper is read first, then lower - entries that already
-+exist are not re-added).  This merged name list is cached in the
-+'struct file' and so remains as long as the file is kept open.  If the
-+directory is opened and read by two processes at the same time, they
-+will each have separate caches.  A seekdir to the start of the
-+directory (offset 0) followed by a readdir will cause the cache to be
-+discarded and rebuilt.
-+
-+This means that changes to the merged directory do not appear while a
-+directory is being read.  This is unlikely to be noticed by many
-+programs.
-+
-+seek offsets are assigned sequentially when the directories are read.
-+Thus if
-+  - read part of a directory
-+  - remember an offset, and close the directory
-+  - re-open the directory some time later
-+  - seek to the remembered offset
-+
-+there may be little correlation between the old and new locations in
-+the list of filenames, particularly if anything has changed in the
-+directory.
-+
-+Readdir on directories that are not merged is simply handled by the
-+underlying directory (upper or lower).
-+
-+
-+Non-directories
-+---------------
-+
-+Objects that are not directories (files, symlinks, device-special
-+files etc.) are presented either from the upper or lower filesystem as
-+appropriate.  When a file in the lower filesystem is accessed in a way
-+the requires write-access, such as opening for write access, changing
-+some metadata etc., the file is first copied from the lower filesystem
-+to the upper filesystem (copy_up).  Note that creating a hard-link
-+also requires copy_up, though of course creation of a symlink does
-+not.
-+
-+The copy_up may turn out to be unnecessary, for example if the file is
-+opened for read-write but the data is not modified.
-+
-+The copy_up process first makes sure that the containing directory
-+exists in the upper filesystem - creating it and any parents as
-+necessary.  It then creates the object with the same metadata (owner,
-+mode, mtime, symlink-target etc.) and then if the object is a file, the
-+data is copied from the lower to the upper filesystem.  Finally any
-+extended attributes are copied up.
-+
-+Once the copy_up is complete, the overlay filesystem simply
-+provides direct access to the newly created file in the upper
-+filesystem - future operations on the file are barely noticed by the
-+overlay filesystem (though an operation on the name of the file such as
-+rename or unlink will of course be noticed and handled).
-+
-+
-+Non-standard behavior
-+---------------------
-+
-+The copy_up operation essentially creates a new, identical file and
-+moves it over to the old name.  The new file may be on a different
-+filesystem, so both st_dev and st_ino of the file may change.
-+
-+Any open files referring to this inode will access the old data and
-+metadata.  Similarly any file locks obtained before copy_up will not
-+apply to the copied up file.
-+
-+On a file is opened with O_RDONLY fchmod(2), fchown(2), futimesat(2)
-+and fsetxattr(2) will fail with EROFS.
-+
-+If a file with multiple hard links is copied up, then this will
-+"break" the link.  Changes will not be propagated to other names
-+referring to the same inode.
-+
-+Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory
-+object in overlayfs will not contain vaid absolute paths, only
-+relative paths leading up to the filesystem's root.  This will be
-+fixed in the future.
-+
-+Some operations are not atomic, for example a crash during copy_up or
-+rename will leave the filesystem in an inconsitent state.  This will
-+be addressed in the future.
-+
-+Changes to underlying filesystems
-+---------------------------------
-+
-+Offline changes, when the overlay is not mounted, are allowed to either
-+the upper or the lower trees.
-+
-+Changes to the underlying filesystems while part of a mounted overlay
-+filesystem are not allowed.  If the underlying filesystem is changed,
-+the behavior of the overlay is undefined, though it will not result in
-+a crash or deadlock.

-Subject: This new driver replaces the old PCEngines Alix 2/3 LED driver with a new
-X-Git-Tag: next-20110812~1^2~75
-X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=2cd7b3e8f8078c214c93a2c60cb845500c92df4a;hp=dc849eae35bbf651ab3ee459f5683e1ff780413d
-
-This new driver replaces the old PCEngines Alix 2/3 LED driver with a new
-driver that controls the LEDs through the leds-gpio driver.  The old
-driver accessed GPIOs directly, which created a conflict and prevented
-also loading the cs5535-gpio driver to read other GPIOs on the Alix board.
- With this new driver, we hook into leds-gpio which in turn uses GPIO to
-control the LEDs and therefore it's possible to control both the LEDs and
-access onboard GPIOs
-
-Driver is moved to platform/geode and any other geode initialisation
-modules should move here also.
-
-This driver is inspired by leds-net5501.c by Alessandro Zummo.
-
-Ideally, leds-net5501.c should also be moved to platform/geode.
-Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
-leds-alix2c - take port address from MSR) by Daniel Mack to perform
-detection of the Alix board.

-Subject: MIPS: Add crash and kdump support
-
-From: http://patchwork.linux-mips.org/patch/1025/
-
-Hello folks,
-
-Please find here MIPS crash and kdump patches.
-This is patch set of 3 patches:
-1. generic MIPS changes (kernel);
-2. MIPS Cavium Octeon board kexec/kdump code (kernel);
-3. Kexec user space MIPS changes.
-
-Patches were tested on the latest linux-mips@ git kernel and the latest
-kexec-tools git on Cavium Octeon 50xx board.
-
-I also made the same code working on RMI XLR/XLS boards for both
-mips32 and mips64 kernels.
-
-Best regards,
-Maxim Uvarov.
-
-------
-[ Zhangjin: Several trivial building failure has been fixed.
-
-Note: the 2nd patch can not be cleanly applied, but may be a good
-reference for the other board development:
-
-	+ MIPS Cavium Octeon board kexec,kdump support
-	http://patchwork.linux-mips.org/patch/1026/
-
-And the 3rd patch has already been merged into the mainline kexec-tools:
-
-	+ some kexec MIPS improvements
-	http://patchwork.linux-mips.org/patch/1027/
-
-kexec-tools is available here:
-
-	+ http://horms.net/projects/kexec/
-	git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git

-From: Wu Zhangjin <wuzhangjin@gmail.com>
-Date: Tue, 11 Jan 2011 18:42:08 +0000
-Subject: MIPS: Kexec: Enhance the support
-
-Changes:
-  o Print more information in machine_kexec() for debugging
-    E.g. with this information, the kexec_start_address has been found
-    it was wrong with 64bit kernel / o32 kexec-tools. Which must be
-    fixed later.
-  o Link relocate_kernel.S to a section for future extension
-    This allows more functions can be added for the kexec relocation
-    part even written in C. to add code into that section, you just need
-    to mark your function or data with __kexec or
-    __attribute__((__section__(".__kexec.relocate")))
-
-TODO:
-
-1. Make 64bit kernel / o32|n32|64 kexec-tools works
-
-Fix the user-space kexec-tools, seems the tool only work for 32bit
-machine. So, we need to add 64bit support for it. The address of the
-entry point(kexec_start_address) is wrong and make the "kexec -e" fail.
-the real entry point must be read from the new kernel image by the
-user-space kexec-tools, otherwise, it will not work.  The above 64bit
-support tested is 64bit kernel with o32 user-space kexec-tools. The root
-cause may be the different definition of virt_to_phys() and
-phys_to_virt() in the kexec-tools and kernel space for 64bit system /
-o32 kernel.
-
-Ref: http://www.linux-mips.org/archives/linux-mips/2009-08/msg00149.html
-
-2. Pass the arguments from kexec-tools to the new kernel image
-
-Please refer to: "MIPS: Loongson: Kexec: Pass parameters to new kernel"

-Subject: MIPS: Kexec: Init the arguments for the new kernel image
-
-Whenever the kexec-tools pass the command lines to the new kernel image,
-init the arguments as the ones for the 1st kernel image. This fixed the
-booting failure of Kexec on YeeLoong.

-Subject: MIPS: Get kernel parameters from kexec-tools
-
-Before, we simply use the command lines from the original bootloader,
-but it is not convenient. Now, we accept the kernel parameters from the
---command-line or --append option of the kexec-tools.  But If not
---command-line or --apend option indicated, will fall back to use the
-ones from the original bootloader.

-+ * The "internal use only" fields in regexp.h are present to pass info from
-+ * compile to execute that permits the execute phase to run lots faster on
-+ * simple cases.  They are:
-+ *
-+ * regstart	char that must begin a match; '\0' if none obvious
-+ * reganch	is the match anchored (at beginning-of-line only)?
-+ * regmust	string (pointer into program) that match must include, or NULL
-+ * regmlen	length of regmust string
-+ *
-+ * Regstart and reganch permit very fast decisions on suitable starting points
-+ * for a match, cutting down the work a lot.  Regmust permits fast rejection
-+ * of lines that cannot possibly match.  The regmust tests are costly enough
-+ * that regcomp() supplies a regmust only if the r.e. contains something
-+ * potentially expensive (at present, the only such thing detected is * or +
-+ * at the start of the r.e., which can involve a lot of backup).  Regmlen is
-+ * supplied because the test in regexec() needs it and regcomp() is computing
-+ * it anyway.

-+ * Structure for regexp "program".  This is essentially a linear encoding
-+ * of a nondeterministic finite-state machine (aka syntax charts or
-+ * "railroad normal form" in parsing technology).  Each node is an opcode
-+ * plus a "next" pointer, possibly plus an operand.  "Next" pointers of
-+ * all nodes except BRANCH implement concatenation; a "next" pointer with
-+ * a BRANCH on both ends of it is connecting two alternatives.  (Here we
-+ * have one of the subtle syntax dependencies:  an individual BRANCH (as
-+ * opposed to a collection of them) is never concatenated with anything
-+ * because of operator precedence.)  The operand of some types of node is
-+ * a literal string; for others, it is a node leading into a sub-FSM.  In
-+ * particular, the operand of a BRANCH node is the first node of the branch.
-+ * (NB this is *not* a tree structure:  the tail of the branch connects
-+ * to the thing following the set of BRANCHes.)  The opcodes are:

-+ * Opcode notes:
-+ *
-+ * BRANCH	The set of branches constituting a single choice are hooked
-+ *		together with their "next" pointers, since precedence prevents
-+ *		anything being concatenated to any individual branch.  The
-+ *		"next" pointer of the last BRANCH in a choice points to the
-+ *		thing following the whole choice.  This is also where the
-+ *		final "next" pointer of each individual branch points; each
-+ *		branch starts with the operand node of a BRANCH node.
-+ *
-+ * BACK		Normal "next" pointers all implicitly point forward; BACK
-+ *		exists to make loop structures possible.
-+ *
-+ * STAR,PLUS	'?', and complex '*' and '+', are implemented as circular
-+ *		BRANCH structures using BACK.  Simple cases (one character
-+ *		per match) are implemented with STAR and PLUS for speed
-+ *		and to minimize recursive plunges.

-+ * OPEN,CLOSE	...are numbered at compile time.

-+ * A node is one char of opcode followed by two chars of "next" pointer.

-+ * An operand, if any, simply follows the node.  (Note that much of the
-+ * code generation knows about this implicit relationship.)

-sch_sfq: fix sfq_enqueue()
-
-commit 8efa88540635 (sch_sfq: avoid giving spurious NET_XMIT_CN signals)
-forgot to call qdisc_tree_decrease_qlen() to signal upper levels that a
-packet (from another flow) was dropped, leading to various problems.
-
-With help from Michal Soltys and Michal Pokrywka, who did a bisection.

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+	pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+	err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+	err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+	mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in			= The SPI data-IN GPIO pin number.
-+gpio_data_out			= The SPI data-OUT GPIO pin number.
-+gpio_clock			= The SPI Clock GPIO pin number.
-+gpio_chipselect			= The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow	= Boolean. If 0, Chipselect is active-HIGH.
-+				  If 1, Chipselect is active-LOW.
-+spi_mode			= The SPI data mode. Can be 0-3.
-+spi_delay			= Enable all delays in the lowlevel bitbanging.
-+max_bus_speed			= The maximum SPI bus speed. In Hertz.
-+
-+register			= Not a configuration parameter.
-+				  Used to register the configured card
-+				  with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow	= 1		(CS active-LOW)
-+spi_mode			= 0		(SPI_MODE_0)
-+spi_delay			= 1		(enabled)
-+max_bus_speed			= 5000000	(5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.
