+Subject: [PATCH] mtd: nand: pxa3xx_nand: add support for partial chunks
+
+This commit is needed to properly support the 8-bits ECC configuration
+with 4KB pages.
+
+When pages larger than 2 KB are used on platforms using the PXA3xx
+NAND controller, the reading/programming operations need to be split
+in chunks of 2 KBs or less because the controller FIFO is limited to
+about 2 KB (i.e a bit more than 2 KB to accommodate OOB data). Due to
+this requirement, the data layout on NAND is a bit strange, with ECC
+interleaved with data, at the end of each chunk.
+
+When a 4-bits ECC configuration is used with 4 KB pages, the physical
+data layout on the NAND looks like this:
+
+| 2048 data | 32 spare | 30 ECC | 2048 data | 32 spare | 30 ECC |
+
+So the data chunks have an equal size, 2080 bytes for each chunk,
+which the driver supports properly.
+
+When a 8-bits ECC configuration is used with 4KB pages, the physical
+data layout on the NAND looks like this:
+
+| 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 64 spare | 30 ECC |
+
+So, the spare area is stored in its own chunk, which has a different
+size than the other chunks. Since OOB is not used by UBIFS, the initial
+implementation of the driver has chosen to not support reading this
+additional "spare" chunk of data.
+
+Unfortunately, Marvell has chosen to store the BBT signature in the
+OOB area. Therefore, if the driver doesn't read this spare area, Linux
+has no way of finding the BBT. It thinks there is no BBT, and rewrites
+one, which U-Boot does not recognize, causing compatibility problems
+between the bootloader and the kernel in terms of NAND usage.
+
+To fix this, this commit implements the support for reading a partial
+last chunk. This support is currently only useful for the case of 8
+bits ECC with 4 KB pages, but it will be useful in the future to
+enable other configurations such as 12 bits and 16 bits ECC with 4 KB
+pages, or 8 bits ECC with 8 KB pages, etc. All those configurations
+have a "last" chunk that doesn't have the same size as the other
+chunks.
+
+In order to implement reading of the last chunk, this commit:
+
+ - Adds a number of new fields to the pxa3xx_nand_info to describe how
+ many full chunks and how many chunks we have, the size of full
+ chunks and partial chunks, both in terms of data area and spare
+ area.
+
+ - Fills in the step_chunk_size and step_spare_size variables to
+ describe how much data and spare should be read/written for the
+ current read/program step.
+
+ - Reworks the state machine to accommodate doing the additional read
+ or program step when a last partial chunk is used.
+
+This commit has been tested on a Marvell Armada 398 DB board, with a
+4KB page NAND, tested in both 4 bits ECC and 8 bits ECC
+configurations. Robert Jarzmik has tested on some PXA platforms.

+Subject: [PATCH] mtd: pxa3xx_nand: Increase the initial chunk size
+
+The chunk size represents the size of the data chunks, which
+is used by the controllers that allow to split transfered data.
+
+However, the initial chunk size is used in a non-splitted way,
+during device identification. Therefore, it must be large enough
+for all the NAND commands issued during device identification.
+This includes NAND_CMD_PARAM which was recently changed to
+transfer up to 2048 bytes (for the redundant parameter pages).
+
+Thus, the initial chunk size should be 2048 as well.
+
+On Armada 370/XP platforms (NFCv2) booted without the keep-config
+devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM
+command:
+
+ [..]
+ pxa3xx-nand f10d0000.nand: This platform can't do DMA on this device
+ pxa3xx-nand f10d0000.nand: Wait time out!!!
+ nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x38

+Subject: [PATCH] mtd: pxa3xx_nand: Fix initial controller configuration
+
+The Data Flash Control Register (NDCR) contains two types
+of parameters: those that are needed for device identification,
+and those that can only be set after device identification.
+
+Therefore, the driver can't set them all at once and instead
+needs to configure the first group before nand_scan_ident()
+and the second group later.
+
+Let's split pxa3xx_nand_config in two halves, and set the
+parameters that depend on the device geometry once this is known.

+ethtool -s eth0 autoneg on
+to disable or enable autonegotiation at run-time.
+Without that functionality, the only way to control the autonegotiation

+
+This is needed if you plan to use the same kernel with

+Subject: [PATCH] net: mvneta: Associate RX queues with each CPU
+
+We enable the percpu interrupt for all the CPU and we just associate a
+CPU to a few queue at the neta level. The mapping between the CPUs and
+the queues is static. The queues are associated to the CPU module the
+number of CPUs. However currently we only use on RX queue for a given
+Ethernet port.

+Subject: [PATCH] net: mvneta: Fix the CPU choice in mvneta_percpu_elect
+
+When passing to the management of multiple RX queue, the
+mvneta_percpu_elect function was broken. The use of the modulo can lead
+to elect the wrong cpu. For example with rxq_def=2, if the CPU 2 goes
+offline and then online, we ended with the third RX queue activated in
+the same time on CPU 0 and CPU2, which lead to a kernel crash.
+
+With this fix, we don't try to get "the closer" CPU if the default CPU is
+gone, now we just use CPU 0 which always be there. Thanks to this, the
+code becomes more readable, easier to maintain and more predicable.

+Subject: [PATCH] net: mvneta: Modify the queue related fields from each cpu
+
+In the MVNETA_INTR_* registers, the queues related fields are per cpu,
+according to the datasheet (comment in [] are added by me):
+"In a multi-CPU system, bits of RX[or TX] queues for which the access by
+the reading[or writing] CPU is disabled are read as 0, and cannot be
+cleared[or written]."
+
+That means that each time we want to manipulate these bits we had to do
+it on each cpu and not only on the current cpu.

+Subject: [PATCH] net: mvneta: The mvneta_percpu_elect function should be
+ atomic
+
+Electing a CPU must be done in an atomic way: it should be done after or
+before the removal/insertion of a CPU and this function is not reentrant.
+
+During the loop of mvneta_percpu_elect we associates the queues to the
+CPUs, if there is a topology change during this loop, then the mapping
+between the CPUs and the queues could be wrong. During this loop the
+interrupt mask is also updating for each CPUs, It should not be changed
+in the same time by other part of the driver.
+
+This patch adds spinlock to create the needed critical sections.

+Subject: [PATCH] net: mvneta: Fix race condition during stopping
+
+When stopping the port, the CPU notifier are still there whereas the
+mvneta_stop_dev function calls mvneta_percpu_disable() on each CPUs.
+It was possible to have a new CPU coming at this point which could be
+racy.
+
+This patch adds a flag preventing executing the code notifier for a new
+CPU when the port is stopping. It also uses the spinlock introduces
+previously. To avoid the deadlock, the lock has been moved outside the
+mvneta_percpu_elect function.

+Subject: [PATCH] net: mvneta: bm: add support for hardware buffer management
+
+Buffer manager (BM) is a dedicated hardware unit that can be used by all
+ethernet ports of Armada XP and 38x SoC's. It allows to offload CPU on RX
+path by sparing DRAM access on refilling buffer pool, hardware-based
+filling of descriptor ring data and better memory utilization due to HW
+arbitration for using 'short' pools for small packets.
+
+Tests performed with A388 SoC working as a network bridge between two
+packet generators showed increase of maximum processed 64B packets by
+~20k (~555k packets with BM enabled vs ~535 packets without BM). Also
+when pushing 1500B-packets with a line rate achieved, CPU load decreased
+from around 25% without BM to 20% with BM.
+
+BM comprise up to 4 buffer pointers' (BP) rings kept in DRAM, which
+are called external BP pools - BPPE. Allocating and releasing buffer
+pointers (BP) to/from BPPE is performed indirectly by write/read access
+to a dedicated internal SRAM, where internal BP pools (BPPI) are placed.
+BM hardware controls status of BPPE automatically, as well as assigning
+proper buffers to RX descriptors. For more details please refer to
+Functional Specification of Armada XP or 38x SoC.
+
+In order to enable support for a separate hardware block, common for all
+ports, a new driver has to be implemented ('mvneta_bm'). It provides
+initialization sequence of address space, clocks, registers, SRAM,
+empty pools' structures and also obtaining optional configuration
+from DT (please refer to device tree binding documentation). mvneta_bm
+exposes also a necessary API to mvneta driver, as well as a dedicated
+structure with BM information (bm_priv), whose presence is used as a
+flag notifying of BM usage by port. It has to be ensured that mvneta_bm
+probe is executed prior to the ones in ports' driver. In case BM is not
+used or its probe fails, mvneta falls back to use software buffer
+management.
+
+A sequence executed in mvneta_probe function is modified in order to have
+an access to needed resources before possible port's BM initialization is
+done. According to port-pools mapping provided by DT appropriate registers
+are configured and the buffer pools are filled. RX path is modified
+accordingly. Becaues the hardware allows a wide variety of configuration
+options, following assumptions are made:
+* using BM mechanisms can be selectively disabled/enabled basing
+ on DT configuration among the ports
+* 'long' pool's single buffer size is tied to port's MTU
+* using 'long' pool by port is obligatory and it cannot be shared
+* using 'short' pool for smaller packets is optional
+* one 'short' pool can be shared among all ports
+
+This commit enables hardware buffer management operation cooperating with
+existing mvneta driver. New device tree binding documentation is added and
+the one of mvneta is updated accordingly.

++ to be chosen between 128 and 16352 and it also has to be aligned to 32.
++ Otherwise the driver would adjust a given number or choose default if
++ not set.
++- pool<0 : 3>,pkt-size: maximum size of a packet accepted by a given buffer
++ pointers' pool (id 0 : 3). It will be taken into consideration only when pool
++ type is 'short'. For 'long' ones it would be overridden by port's MTU.
++ If not set a driver will choose a default value.
++
++In order to see how to hook the BM to a given ethernet port, please
++refer to Documentation/devicetree/bindings/net/marvell-armada-370-neta.txt.
++
++Example:
++
++- main node:
++
++bm: bm at c8000 {
++ compatible = "marvell,armada-380-neta-bm";
++ reg = <0xc8000 0xac>;
++ clocks = <&gateclk 13>;
++ internal-mem = <&bm_bppi>;
++ status = "okay";
++ pool2,capacity = <4096>;
++ pool1,pkt-size = <512>;
++};
++
++- internal SRAM node:
++
++bm_bppi: bm-bppi {
++ compatible = "mmio-sram";
++ reg = <MBUS_ID(0x0c, 0x04) 0 0x100000>;
++ ranges = <0 MBUS_ID(0x0c, 0x04) 0 0x100000>;
++ #address-cells = <1>;

+Subject: [PATCH] net: mvneta: Fix spinlock usage
+
+In the previous patch, the spinlock was not initialized. While it didn't
+cause any trouble yet it could be a problem to use it uninitialized.
+
+The most annoying part was the critical section protected by the spinlock
+in mvneta_stop(). Some of the functions could sleep as pointed when
+activated CONFIG_DEBUG_ATOMIC_SLEEP. Actually, in mvneta_stop() we only
+need to protect the is_stopped flagged, indeed the code of the notifier
+for CPU online is protected by the same spinlock, so when we get the
+lock, the notifer work is done.

+
+The mvneta is also used in some Marvell berlin family SoCs which may
+have 64bytes cacheline size. Replace the MVNETA_CPU_D_CACHE_LINE_SIZE
+usage with L1_CACHE_BYTES.
+
+And since dma_alloc_coherent() is always cacheline size aligned, so
+remove the align checks.

+
+After enabling per-cpu processing it appeared that under heavy load
+changing MTU can result in blocking all port's interrupts and

+
+This commit fixes above issue by disabling percpu interrupts for the

+Subject: [PATCH] ARM: dts: armada-38x: enable buffer manager support on Armada
+ 38x boards
+
+Since mvneta driver supports using hardware buffer management (BM), in
+order to use it, board files have to be adjusted accordingly. This commit
+enables BM on:
+* A385-DB-AP - each port has its own pool for long and common pool for
+short packets,
+* A388-ClearFog - same as above,
+* A388-DB - to each port unique 'short' and 'long' pools are mapped,
+* A388-GP - same as above.
+
+Moreover appropriate entry is added to 'soc' node ranges, as well as "okay"
+status for 'bm' and 'bm-bppi' (internal SRAM) nodes.

+Revert "mtd: pxa3xx-nand: handle PIO in threaded interrupt"
+
+This reverts commit 24542257a3b987025d4b998ec2d15e556c98ad3f
+This upstream change has been causing spurious timeouts on accesses
+to the NAND flash if something else on the system is causing
+significant latency.
+
+Nothing guarantees that the thread will run in time, so the
+usual timeout is unreliable.

+Subject: [PATCH 710/744] phy: convert swphy register generation to tabular
+ form
+
+Convert the swphy register generation to tabular form which allows us
+to eliminate multiple switch() statements. This results in a smaller
+object code size, more efficient, and easier to add support for faster
+speeds.

+Subject: [PATCH 713/744] phy: improve safety of fixed-phy MII register reading
+
+There is no prevention of a concurrent call to both fixed_mdio_read()
+and fixed_phy_update_state(), which can result in the state being
+modified while it's being inspected. Fix this by using a seqcount
+to detect modifications, and memcpy()ing the state.
+
+We remain slightly naughty here, calling link_update() and updating
+the link status within the read-side loop - which would need rework
+of the design to change.

+Subject: [PATCH 714/744] phy: provide a hook for link up/link down events
+
+Sometimes, we need to do additional work between the PHY coming up and
+marking the carrier present - for example, we may need to wait for the
+PHY to MAC link to finish negotiation. This changes phylib to provide
+a notification function pointer which avoids the built-in
+netif_carrier_on() and netif_carrier_off() functions.
+
+Standard ->adjust_link functionality is provided by hooking a helper
+into the new ->phy_link_change method.

+Subject: [PATCH 718/744] phylink: add phylink infrastructure
+
+The link between the ethernet MAC and its PHY has become more complex
+as the interface evolves. This is especially true with serdes links,
+where the part of the PHY is effectively integrated into the MAC.
+
+Serdes links can be connected to a variety of devices, including SFF
+modules soldered down onto the board with the MAC, a SFP cage with
+a hotpluggable SFP module which may contain a PHY or directly modulate
+the serdes signals onto optical media with or without a PHY, or even
+a classical PHY connection.
+
+Moreover, the negotiation information on serdes links comes in two
+varieties - SGMII mode, where the PHY provides its speed/duplex/flow
+control information to the MAC, and 1000base-X mode where both ends
+exchange their abilities and each resolve the link capabilities.
+
+This means we need a more flexible means to support these arrangements,
+particularly with the hotpluggable nature of SFP, where the PHY can
+be attached or detached after the network device has been brought up.
+
+Ethtool information can come from multiple sources:
+- we may have a PHY operating in either SGMII or 1000base-X mode, in
+ which case we take ethtool/mii data directly from the PHY.
+- we may have a optical SFP module without a PHY, with the MAC
+ operating in 1000base-X mode - the ethtool/mii data needs to come
+ from the MAC.
+- we may have a copper SFP module with a PHY whic can't be accessed,
+ which means we need to take ethtool/mii data from the MAC.
+
+Phylink aims to solve this by providing an intermediary between the
+MAC and PHY, providing a safe way for PHYs to be hotplugged, and
+allowing a SFP driver to reconfigure the serdes connection.
+
+Phylink also takes over support of fixed link connections, where
+the speed/duplex/flow control are fixed, but link status may be
+controlled by a GPIO signal. By avoiding the fixed-phy implementation,
+phylink can provide a faster response to link events: fixed-phy has
+to wait for phylib to operate its state machine, which can take
+several seconds. In comparison, phylink takes milliseconds.

+Subject: [PATCH 719/744] phylink: add hooks for SFP support
+
+Add support to phylink for SFP, which needs to control and configure
+the ethernet MAC link state. Specifically, SFP needs to:
+
+1. set the negotiation mode between SGMII and 1000base-X
+2. attach and detach the module PHY
+3. prevent the link coming up when errors are reported
+
+In the absence of a PHY, we also need to set the ethtool port type
+according to the module plugged in.

+Subject: [PATCH 720/744] sfp: add phylink based SFP module support
+
+Add support for SFP hotpluggable modules via phylink. This supports
+both copper and optical SFP modules, which require different Serdes
+modes in order to properly negotiate the link.
+
+Optical SFP modules typically require the Serdes link to be talking
+1000base-X mode - this is the gigabit ethernet mode defined by the
+802.3 standard.
+
+Copper SFP modules typically integrate a PHY in the module to convert
+from Serdes to copper, and the PHY will be configured by the vendor
+to either present a 1000base-X Serdes link (for fixed 1000base-T) or
+a SGMII Serdes link. However, this is vendor defined, so we instead
+detect the PHY, switch the link to SGMII mode, and use traditional
+PHY based negotiation.

+Armada 370/XP devices can 'blink' gpio lines with a configurable on
+and off period. This can be modelled as a PWM.
+
+However, there are only two sets of PWM configuration registers for
+all the gpio lines. This driver simply allows a single gpio line per
+gpio chip of 32 lines to be used as a PWM. Attempts to use more return
+EBUSY.
+
+Due to the interleaving of registers it is not simple to separate the
+PWM driver from the gpio driver. Thus the gpio driver has been
+extended with a PWM driver.
