-+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
-+case 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 for the overlay-filesystem,
-+all non-directory objects will report an st_dev whichever of 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. 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 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).
-+
-+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. This is not yet enforced, but will be in
-+the future.

-MIPS: allow disabling the kernel FPU emulator
-
-This patch allows turning off the in-kernel Algorithmics
-FPU emulator support, which allows one to save a couple of
-precious blocks on an embedded system.

-- is not needed. These Blocks are reserved per partition, so if
-- you have very small partitions the default (10) may be a mess

-+ * 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

-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.
