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:

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.

Subject: [PATCH] mvneta: implement ethtool autonegotiation control
This patch allows to do
ethtool -s eth0 autoneg off
ethtool -s eth0 autoneg on
to disable or enable autonegotiation at run-time.
Without that functionality, the only way to control the autonegotiation
is to modify the device tree.
This is needed if you plan to use the same kernel with
different ethernet switches, the ones that support the in-band
status and the ones that not.

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: Add naive RSS support
This patch adds the support for the RSS related ethtool
function. Currently it only uses one entry in the indirection table which
allows associating an mvneta interface to a given CPU.

Using the macro on_each_cpu (instead of a for_each_* loop) also ensures

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: 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

Armada 38x network controller supports hardware buffer management (BM).
Since it is now enabled in mvneta driver, appropriate nodes can be added
to armada-38x.dtsi - for the actual common BM unit (bm@c8000) and its
internal SRAM (bm-bppi), which is used for indirect access to buffer
pointer ring residing in DRAM.
Pools - ports mapping, bm-bppi entry in 'soc' node's ranges and optional
parameters are supposed to be set in board files.

Armada XP network controller supports hardware buffer management (BM).
Since it is now enabled in mvneta driver, appropriate nodes can be added
to armada-xp.dtsi - for the actual common BM unit (bm@c0000) and its
internal SRAM (bm-bppi), which is used for indirect access to buffer
pointer ring residing in DRAM.
Pools - ports mapping, bm-bppi entry in 'soc' node's ranges and optional
parameters are supposed to be set in board files.

Subject: [PATCH] ARM: dts: Add SolidRun Armada 388 Clearfog A1 DT file
Add support for the SolidRun Armada 388 Clearfog A1 board. This board
has an Armada 388 microsom, dedicated gigabit ethernet, six switched
gigabit ethernet ports, SFP cage, two Mini-PCIe/mSATA slots, a m.2 SATA
slot, and a MikroBUS connector to allow MikroBUS modules to be added.
This DT file adds support for all board facilities with the exception
of full SFP support.

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 712/744] phy: generate swphy registers on the fly
Generate software phy registers as and when requested, rather than
duplicating the state in fixed_phy. This allows us to eliminate
the duplicate storage of of the same data, which is only different
in format.
As fixed_phy_update_regs() no longer updates register state, rename
it to fixed_phy_update().

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 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 726/744] phylink: add flow control support
Add flow control support, including ethtool support, to phylink. We
add support to allow ethtool to get and set the current flow control
settings, and the 802.3 specified resolution for the local and remote
link partner abilities.

Subject: [PATCH 731/744] net: mvneta: add EEE support
Add EEE support to mvneta. This allows us to enable the low power idle
support at MAC level if there is a PHY attached through phylink which
supports LPI. The appropriate ethtool support is provided to allow the
feature to be controlled, including ethtool statistics for EEE wakeup
errors.

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.

Subject: [PATCH] sfp: retry phy probe if unsuccessful
Some phys seem to take longer than 50 ms to come out of reset, so retry
until we find a phy.

The hardware queue scheduling is apparently configured with fixed
priorities, which creates a nasty fairness issue where traffic from one
CPU can starve traffic from all other CPUs.
Work around this issue by forcing all tx packets to go through one CPU,
until this issue is fixed properly.
