+Date: Tue, 6 Oct 2009 04:04:15 +0100
+Subject: [PATCH] Squashfs: add a decompressor framework
+
+This adds a decompressor framework which allows multiple compression
+algorithms to be cleanly supported.
+
+Also update zlib wrapper and other code to use the new framework.

+Subject: [PATCH] Squashfs: add decompressor entries for lzma and lzo
+
+Add knowledge of lzma/lzo compression formats to the decompressor
+framework.  For now these are added as unsupported.  Without
+these entries lzma/lzo compressed filesystems will be flagged as
+having unknown compression which is undesirable.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code.  Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+MIPS: allow disabling the kernel FPU emulator

+FPU emulator support, which allows one to save a couple of

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only).  We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

++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.
