-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-For reading flash content we use MMIO but it's possible to read only
-first 16 MiB this way. It's simply an arch design/limitation.
-To support flash sizes bigger than 16 MiB implement indirect access
-using ChipCommon registers.
-This has been tested using MX25L25635F.

-Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change simplifies main parsing loop logic a bit. In future it may
-be useful for moving TRX support to separated module / parser (if we
-implement support for them at some point).
-Finally parsing TRX at the end puts us in a better position as we have
-better flash layout knowledge. It may be useful e.g. if it appears there
-is more than 1 TRX partition.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With the S25FL127S nor flash part, each writing to the configuration
-register takes hundreds of ms. During that time, no more accesses to
-the flash should be done (even reads).
-
-This commit adds a wait loop after the register writing until the flash
-finishes its work.
-
-This issue could make rootfs mounting fail when the latter was done too
-much closely to this quad enable bit setting step. And in this case, a
-driver as UBIFS may try to recover the filesystem and may broke it
-completely.

-
-Xilinx Spartan-3AN FPGAs contain an In-System Flash where they keep
-their configuration data and (optionally) some user data.
-
-The protocol of this flash follows most of the spi-nor standard. With
-the following differences:
-
-- Page size might not be a power of two.
-- The address calculation (default addressing mode).
-- The spi nor commands used.
-
-Protocol is described on Xilinx User Guide UG333

-This macro triggers the display of a warning message almost every time we
-use a UBI file-system because a write operation is performed at offset 64,
-which is in the middle of the SPI NOR memory page. This is a valid
-operation for ubifs.
-
-Hence this warning is pretty annoying and useless so we just remove it.

-Subject: [PATCH] mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address
- op codes
-
-This patch renames the SPINOR_OP_* macros of the 4-byte address
-instruction set so the new names all share a common pattern: the 4-byte
-address name is built from the 3-byte address name appending the "_4B"
-suffix.
-
-The patch also introduces new op codes to support other SPI protocols such
-as SPI 1-4-4 and SPI 1-2-2.
-
-This is a transitional patch and will help a later patch of spi-nor.c
-to automate the translation from the 3-byte address op codes into their
-4-byte address version.

-Subject: [PATCH] mtd: spi-nor: add a stateless method to support memory size
- above 128Mib
-
-This patch provides an alternative mean to support memory above 16MiB
-(128Mib) by replacing 3byte address op codes by their associated 4byte
-address versions.
-
-Using the dedicated 4byte address op codes doesn't change the internal
-state of the SPI NOR memory as opposed to using other means such as
-updating a Base Address Register (BAR) and sending command to enter/leave
-the 4byte mode.
-
-Hence when a CPU reset occurs, early bootloaders don't need to be aware
-of BAR value or 4byte mode being enabled: they can still access the first
-16MiB of the SPI NOR memory using the regular 3byte address op codes.

-erasesize is meaningful for flash devices but for SRAM there is no
-concept of an erase block so erasesize is set to 0. When partitioning
-these devices instead of ensuring partitions fall on erasesize
-boundaries we ensure they fall on writesize boundaries.

-When support for sysfs "offset" file was added it missed to update the

-Subject: [PATCH] mtd: partitions: rename "master" to the "parent" where
- appropriate
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This prepares mtd subsystem for the new feature: subpartitions. In some
-cases flash device partition can be a container with extra subpartitions
-(volumes).
-
-So far there was a flat structure implemented. One master (flash device)
-could be partitioned into few partitions. Every partition got its master
-and it was enough to get things running.
-
-To support subpartitions we need to store pointer to the parent for each
-partition. This is required to implement more natural tree structure and
-handle all recursion and offsets calculation.
-
-To make code consistent this patch renamed "master" to the "parent" in
-places where we can be dealing with subpartitions.

-
-Some flash device partitions can be containers with extra subpartitions
-(volumes). All callbacks are already capable of this additional level of
-indirection.
-
-This patch makes sure we always display subpartitions using a tree
-structure and takes care of deleting subpartitions when parent gets
-removed.

-Subject: [PATCH] mtd: partitions: add support for partition parsers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some devices have partitions that are kind of containers with extra
-subpartitions / volumes instead of e.g. a simple filesystem data. To
-support such cases we need to first create normal flash device
-partitions and then take care of these special ones.
-
-It's very common case for home routers. Depending on the vendor there
-are formats like TRX, Seama, TP-Link, WRGG & more. All of them are used
-to embed few partitions into a single one / single firmware file.
-
-Ideally all vendors would use some well documented / standardized format
-like UBI (and some probably start doing so), but there are still
-countless devices on the market using these poor vendor specific
-formats.
-
-This patch extends MTD subsystem by allowing to specify list of parsers
-that should be tried for a given partition. Supporting such poor formats
-is highly unlikely to be the top priority so these changes try to
-minimize maintenance cost to the minimum. It reuses existing code for
-these new parsers and just adds a one property and one new function.
-
-This implementation requires setting partition parsers in a flash
-parser. A proper change of bcm47xxpart will follow and in the future we
-will hopefully also find a solution for doing it with ofpart
-("fixed-partitions").

-
-This change is a small cleanup of mtd_device_parse_register(). When
-using MTD_PARTITIONED_MASTER it makes sure a master MTD is registered
-before dealing with partitions. The advantage of this is not mixing
-code handling master MTD with code handling partitions.
-
-This commit doesn't change any behavior except from a slightly different
-failure code path. The new code may need to call del_mtd_device when
-something goes wrong.

-Subject: [PATCH] mtd: get rid of the mtd_add_device_partitions()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This simplifies code a bit by:
-1) Avoiding an extra (tiny) function
-2) Checking for amount of parsed (found) partitions just once
-3) Avoiding clearing/filling struct mtd_partitions manually
-
-With this commit proper functions are called directly from the
-mtd_device_parse_register(). It doesn't need to use minor tricks like
-memsetting struct to 0 to trigger an expected
-mtd_add_device_partitions() behavior.

-Subject: [PATCH 1/3] net: bgmac: allocate struct bgmac just once & don't copy
- it
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far were were allocating struct bgmac in 3 places: platform code,
-bcma code and shared bgmac_enet_probe function. The reason for this was
-bgmac_enet_probe:
-1) Requiring early-filled struct bgmac
-2) Calling alloc_etherdev on its own in order to use netdev_priv later
-
-This solution got few drawbacks:
-1) Was duplicating allocating code
-2) Required copying early-filled struct
-3) Resulted in platform/bcma code having access only to unused struct
-
-Solve this situation by simply extracting some probe code into the new
-bgmac_alloc function.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Adding struct bcma_mdio was a workaround for bcma code not having access
-to the struct bgmac used in the core code. Now we don't duplicate this
-struct we can just use it internally in bcma code.
-
-This simplifies code & allows access to all bgmac driver details from
-all places in bcma code.

-Subject: [PATCH] net: bgmac: enable master mode for BCM54210E and B50212E PHYs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-There are 4 very similar PHYs:
-0x600d84a1: BCM54210E (rev B0)
-0x600d84a2: BCM54210E (rev B1)
-0x600d84a5: B50212E (rev B0)
-0x600d84a6: B50212E (rev B1)
-that need setting master mode manually. It's because they run in slave
-mode by default with Automatic Slave/Master configuration disabled which
-can lead to unreliable connection with massive ping loss.
-
-So far it was reported for a board with BCM47189 SoC and B50212E B1 PHY
-connected to the bgmac supported ethernet device. Telling PHY driver to
-setup PHY properly solves this issue.

-In preparation for adding support for Wirespeed/downshift, we need to

-
-Broadcom PHYs expose a number of PHY error counters: receive errors,
-false carrier sense, SerDes BER count, local and remote receive errors.
-Add support code to allow retrieving these error counters. Since the
-Broadcom PHY library code is used by several drivers, make it possible
-for them to specify the storage for the software copy of the statistics.

-Subject: [PATCH] net: phy: broadcom: rehook BCM54612E specific init
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This extra BCM54612E code in PHY driver isn't really aneg specific. Even
-without it aneg works OK but the problem is no packets pass through PHY.
-
-Moreover putting this code inside config_aneg callback didn't allow
-resuming PHY correctly. When driver called phy_stop and phy_start it was
-putting PHY machine into RESUMING state. After that machine was
-switching into AN and NOLINK without ever calling phy_start_aneg. This
-prevented this extra setup from being called and PHY didn't work.
-
-This change has been verified to fix network on BCM47186B0 SoC device
-with BCM54612E.

-Subject: [PATCH] net: phy: broadcom: support new device flag for setting
- master mode
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some of Broadcom's PHYs run by default in slave mode with Automatic
-Slave/Master configuration disabled. It stops them from working properly
-with some devices.
-
-So far it has been verified for BCM54210E and BCM50212E which don't
-work well with Intel's I217-LM and I218-LM:
-http://ark.intel.com/products/60019/Intel-Ethernet-Connection-I217-LM
-http://ark.intel.com/products/71307/Intel-Ethernet-Connection-I218-LM
-I was told there is massive ping loss.
-
-This commit adds support for a new flag which can be set by an ethernet
-driver to fixup PHY setup.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-These new functions allow passing an additional device_node argument
-that will be internally set for created LED device. Thanks to this LED
-core code and triggers will be able to access DT node for reading extra
-info.
-
-The easiest solution for achieving this was reworking old functions to
-more generic ones & adding simple defines for API compatibility.

-
-Upstream GCC uses a libgcc function for saving/restoring registers. This
-makes the code bigger, and upstream kernels need to carry that function
-for every single kernel module. Our GCC is patched to avoid those
-references, so we can drop the extra bloat for modules.

-Subject: [PATCH V10 1/3] mtd: partitions: add of_match_table parser matching
- for the "ofpart" type
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In order to properly support compatibility strings as described in the
-bindings/mtd/partition.txt "ofpart" type should be treated as an
-indication for looking into OF. MTD should check "compatible" property
-and search for a matching parser rather than blindly trying the one
-supporting "fixed-partitions".
-
-It also means that existing "fixed-partitions" parser should get renamed
-to use a more meaningful name.
-
-This commit achievies that aim by introducing a new mtd_part_of_parse().
-It works by looking for a matching parser for every string in the
-"compatibility" property (starting with the most specific one).
-
-Please note that driver-specified parsers still take a precedence. It's
-assumed that driver providing a parser type has a good reason for that
-(e.g. having platform data with device-specific info). Also doing
-otherwise could break existing setups. The same applies to using default
-parsers (including "cmdlinepart") as some overwrite DT data with cmdline
-argument.
-
-Partition parsers can now provide an of_match_table to enable
-flash<-->parser matching via device tree as documented in the
-mtd/partition.txt.
-
-This support is currently limited to built-in parsers as it uses
-request_module() and friends. This should be sufficient for most cases
-though as compiling parsers as modules isn't a common choice.

- SPI transfer
-
-Some flash controllers, e.g. on the ath79 platform can support a fast
-flash read via memory mapping, but only if the flash chip is in
-3-byte address mode.
-
-Since spi_flash_read_supported does not have access to the same data as
-spi_flash_read, the driver can't detect an unsupported call until m25p80
-has decided to use spi_flash_read.
-
-Allow the driver to indicate a fallback to a regular SPI transfer by
-returning -EOPNOTSUPP

-
-on some platforms, erase suspend leads to data corruption and lockups when write
-ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
-rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
-simply disable erase suspend, as it will usually not produce any useful gain on
-the small filesystems used on embedded hardware.

-Subject: [PATCH] mtd: spi-nor: support limiting 4K sectors support based on
- flash size
-
-Some devices need 4K sectors to be able to deal with small flash chips.
-For instance, w25x05 is 64 KiB in size, and without 4K sectors, the
-entire chip is just one erase block.
-On bigger flash chip sizes, using 4K sectors can significantly slow down
-many operations, including using a writable filesystem. There are several
-platforms where it makes sense to use a single kernel on both kinds of
-devices.
-
-To support this properly, allow configuring an upper flash chip size
-limit for 4K sectors support.

-There're some discussions in mailing lists proposing to disable
-that particular check alltogether and magically all seem to work
-fine with muted warning.
-
-Anyways new thread on that regard could be found here:
-http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html

-Let's see what comes out of that new discussion, hopefully patching

-There're some discussions in mailing lists proposing to disable
-that particular check alltogether and magically all seem to work
-fine with muted warning.
-
-Anyways new thread on that regard could be found here:
-http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
-
-Let's see what comes out of that new discussion, hopefully patching
-of generic USB stuff won't be required then.

-Subject: libata: add ledtrig support
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.
