Subject: [PATCH 1/5] block: add support for defining read-only partitions
Add support for defining read-only partitions and complete support for
it in the cmdline partition parser as the additional "ro" after a
partition is scanned but never actually applied.

Subject: [PATCH 3/5] block: introduce add_disk_fwnode()
Introduce add_disk_fwnode() as a replacement of device_add_disk() that
permits to pass and attach a fwnode to disk dev.
This variant can be useful for eMMC that might have the partition table
for the disk defined in DT. A parser can later make use of the attached
fwnode to parse the related table and init the hardcoded partition for
the disk.
device_add_disk() is converted to a simple wrapper of add_disk_fwnode()
with the fwnode entry set as NULL.

Subject: [PATCH 4/5] mmc: block: attach partitions fwnode if found in mmc-card
Attach partitions fwnode if found in mmc-card and register disk with it.
This permits block partition to reference the node and register a
partition table defined in DT for the special case for embedded device
that doesn't have a partition table flashed but have an hardcoded
partition table passed from the system.
JEDEC BOOT partition boot0/boot1 are supported but in DT we refer with
the JEDEC name of boot1 and boot2 to better adhere to documentation.
Also JEDEC GP partition gp0/1/2/3 are supported but in DT we refer with
the JEDEC name of gp1/2/3/4 to better adhere to documentration.

Subject: [PATCH 5/5] block: add support for partition table defined in OF
Add support for partition table defined in Device Tree. Similar to how
it's done with MTD, add support for defining a fixed partition table in
device tree.
A common scenario for this is fixed block (eMMC) embedded devices that
have no MBR or GPT partition table to save storage space. Bootloader
access the block device with absolute address of data.
This is to complete the functionality with an equivalent implementation
with providing partition table with bootargs, for case where the booargs
can't be modified and tweaking the Device Tree is the only solution to
have an usabe partition table.
The implementation follow the fixed-partitions parser used on MTD
devices where a "partitions" node is expected to be declared with
"fixed-partitions" compatible in the OF node of the disk device
(mmc-card for eMMC for example) and each child node declare a label
and a reg with offset and size. If label is not declared, the node name
is used as fallback. Eventually is also possible to declare the read-only
property to flag the partition as read-only.

Subject: [PATCH] kconfig: abort configuration on unset symbol
When a target configuration has unset Kconfig symbols, the build will
fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
In case OpenWrt is compiled without either of these preconditions, the
build will succeed with the symbols in question being unset.
Modify the kernel configuration in a way it fails on unset symbols
regardless of the aforementioned preconditions.

Subject: [PATCH 2/2] mtd: blktrans: call add disks after mtd device
To: linux-mtd@lists.infradead.org
Cc: Vignesh Raghavendra <vigneshr@ti.com>,
Richard Weinberger <richard@nod.at>,
Miquel Raynal <miquel.raynal@bootlin.com>,
David Woodhouse <dwmw2@infradead.org>
Calling device_add_disk while holding mtd_table_mutex leads
to deadlock in case part_bits!=0 as block partition parsers
will try to open the newly created disks, trying to acquire
mutex once again.
Move device_add_disk to additional function called after
add partitions of an MTD device have been added and locks
have been released.

Subject: [PATCH] drivers: mtd: parsers: add nvmem support to cmdlinepart
Assuming cmdlinepart is only one level deep partition scheme and that
static partition are also defined in DTS, we can assign an of_node for
partition declared from bootargs. cmdlinepart have priority than
fiexed-partition parser so in this specific case the parser doesn't
assign an of_node. Fix this by searching a defined of_node using a
similar fixed_partition parser and if a partition is found with the same
label, check that it has the same offset and size and return the DT
of_node to correctly use NVMEM cells.

To set the default size of the connection tracking hash table, a divider of
16384 becomes inadequate for a router handling lots of connections. Divide by
2048 instead, making the default size scale better with the available RAM.

Subject: [PATCH] drivers: net: phy: aquantia: enable AQR112 and AQR412
Adds support for AQR112 and AQR412 which is mostly based on existing code
with the addition of code configuring the protocol on system side.
This allows changing the system side protocol without having to deploy a
different firmware on the PHY.

Subject: [PATCH] net: phy: mediatek-ge: add LED configuration interface
This adds a small hack similar to the one used for ar8xxx switches to
read a reg:value map for configuring the LED configuration registers.
This allows OpenWrt to write device-specific LED action as well as blink
configurations. It is unlikely to be accepted upstream, as upstream
plans on integrating their own framework for handling these LEDs.

This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
page_to_pfn anymore.
The following output was generated with two hacked in printk statements:
printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
printk("after %p\n", mem_map);
Output:
[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
[ 0.000000] after 8851b280
As seen in the first line mem_map with subtraction of offset does not equal the
mem_map after subtraction of ARCH_PFN_OFFSET.
After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
previously calculated offset is zero for the named platform it is able to boot
4.4 and 4.9-rc7 again.

Subject: bridge: allow receiption on disabled port
When an ethernet device is enslaved to a bridge, and the bridge STP
detects loss of carrier (or operational state down), then normally
packet receiption is blocked.
This breaks control applications like WPA which maybe expecting to
receive packets to negotiate to bring link up. The bridge needs to
block forwarding packets from these disabled ports, but there is no
hard requirement to not allow local packet delivery.

Subject: [PATCH] net: bridge: do not send arp replies if src and target hw
addr is the same
There are broken devices in the wild that handle duplicate IP address
detection by sending out ARP requests for the IP that they received from a
DHCP server and refuse the address if they get a reply.
When proxyarp is enabled, they would go into a loop of requesting an address
and then NAKing it again.

Subject: [PATCH 1/2] rtc: rs5c372: support alarms up to 1 week
The Ricoh R2221x, R2223x, RS5C372, RV5C387A chips can handle 1 week
alarms.
Read the "wday" alarm register and convert it to a date to support up 1
week in our driver.

Subject: [PATCH] MIPS: Add barriers between dcache & icache flushes
Index-based cache operations may be arbitrarily reordered by out of
order CPUs. Thus code which writes back the dcache & then invalidates
the icache using indexed cache ops must include a barrier between
operating on the 2 caches in order to prevent the scenario in which:
- icache invalidation occurs.
- icache fetch occurs, due to speculation.
- dcache writeback occurs.
If the above were allowed to happen then the icache would contain stale
data. Forcing the dcache writeback to complete before the icache
invalidation avoids this.

Subject: [PATCH] arc add OWRTDTB section
This change allows OpenWRT to patch resulting kernel binary with
external .dtb.
That allows us to re-use exactky the same vmlinux on different boards
given its ARC core configurations match (at least cache line sizes etc).
""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
.dtb right after it, keeping the string in place.

Subject: arc: enable unaligned access in kernel mode
This enables misaligned access handling even in kernel mode.
Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
here and there and to cope with that without fixing stuff in the drivers
we're just gracefully handling it on ARC.

Subject: [PATCH] mips: kernel: fix detect_memory_region() function
1. Do not use memcmp() on unallocated memory, as the new introduced
fortify dynamic object size check[1] will report unexpected result.
2. Use a fixed pattern instead of a random function pointer as the
magic value.
3. Flip magic value and double check it.
4. Enable this feature only for 32-bit CPUs. Currently, only ath79 and
ralink CPUs are using it.

+ help
+ MyLoader is a bootloader which allows the user to define partitions
+ in flash devices, by putting a table in the second erase block
+ on the device, similar to a partition table. This table gives the
+ offsets and lengths of the user defined partitions.
+
+ If you need code which can detect and parse these tables, and
+ register MTD 'partitions' corresponding to each image detected,
+ enable this option.
+
+ You will still need the parsing functions to be called by the driver
+ for your particular device. It won't happen automatically.

Subject: [PATCH 5/9] nvmem: implement block NVMEM provider
On embedded devices using an eMMC it is common that one or more partitions
on the eMMC are used to store MAC addresses and Wi-Fi calibration EEPROM
data. Allow referencing any block device or partition in Device Tree to
allow e.g. Ethernet and Wi-Fi drivers accessing them via the NVMEM layer.

Subject: kernel: disable cfi cmdset 0002 erase suspend
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 497/497] mtd: mtdconcat: add dt driver for concat devices
Some mtd drivers like physmap variants have support for concatenating
multiple mtd devices, but there is no generic way to define such a
concat device from within the device tree.
This is useful for some SoC boards that use multiple flash chips as
memory banks of a single mtd device, with partitions spanning chip
borders.
This commit adds a driver for creating virtual mtd-concat devices. They
must have a compatible = "mtd-concat" line, and define a list of devices
to concat in the 'devices' property, for example:
flash {
compatible = "mtd-concat";
devices = <&flash0 &flash1>;
partitions {
...
};
};
The driver is added to the very end of the mtd Makefile to increase the
likelyhood of all child devices already being loaded at the time of
probing, preventing unnecessary deferred probes.

Macronix flash chips seem to consist of only one status register.
These chips will not work with the "16-bit Write Status (01h) Command".
Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
Tested with MX25L6405D.

Subject: [PATCH 1/2] block: add uImage.FIT subimage block driver
Add a small block driver which exposes filesystem sub-images contained
in U-Boot uImage.FIT images as block devices.
The uImage.FIT image has to be stored directly on a block device or
partition, MTD device or partition, or UBI volume.
The driver is intended for systems using the U-Boot bootloader and
uses the root device hint left by the bootloader (or the user) in
the 'chosen' section of the device-tree.
Example:
/dts-v1/;
/ {
chosen {
rootdisk = <&mmc0_part3>;
};
};

Subject: [PATCH] net_sched/codel: do not defer queue length update
When codel wants to drop last packet in ->dequeue() it cannot call
qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
about zero qlen and HTB/HFSC will deactivate class. The same class will
be deactivated second time by caller of ->dequeue(). Currently codel and
fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
but there is no active classes.
This patch update parent queue length immediately: just temporary increase
qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
if we have skb to return.
This might open another problem in HFSC - now operation peek could fail and
deactivate parent class.
