c61c709f4e apm821xx: Force Ethernet PHYID on MX60/MX60W
The MX60's uboot disables all the PHYs before starting linux.
This causes the PHY/switch detection code to malfunction
almost all of the time. To get around this, set a compatible
flag to force PHYID.

fb528b1674 ipq40xx: unbundle firmware and board file
Don't select the firmware with the board file, it prevents an easy use
of the -ct ath10k firmware. Select the firmware within the default
packages instead.

Remove the per device selection of the firmware now that it the

970f1914be ipq40xx: add support for Netgear EX6100v2/EX6150v2
Specifications:
SOC:	Qualcomm IPQ4018 (DAKOTA) ARM Quad-Core
RAM:	256 MB Winbond W632GU6KB12J
FLASH:	16 MiB Macronix MX25L12805D
ETH:	Qualcomm QCA8072
WLAN1:  Qualcomm Atheros QCA4018 2.4GHz 802.11b/g/n/ac 2x2
WLAN2:  Qualcomm Atheros QCA4018 5GHz 802.11n/ac
	1x1 (EX6100)
	2x2 (EX6150)
INPUT:  Power, WPS, reset button
	AP / Range-extender toggle
LED:	Power, Router, Extender (dual), WPS, Left-/Right-arrow
SERIAL:	Header next to QCA8072 chip.
	VCC, TX, RX, GND (Square hole is VCC)
	WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
        The Serial setting is 115200-8-N-1.

Tested and working:
 - Ethernet
 - 2.4 GHz WiFi (Correct MAC-address)
 - 5 GHz WiFi (Correct MAC-address)
 - Factory installation from WebIF
 - Factory installation from tftp
 - OpenWRT sysupgrade (Preserving and non-preserving)
 - LEDs
 - Buttons

Not Working:
 - AP/Extender toggle-switch

Untested:
 - Support on EX6100v2. They share the same GPL-Code and vendor-images.
   The 6100v2 seems to lack one 5GHz stream and differs in the 5GHz
   board-blob. I only own a EX6150v2, therefore i am only able to verify
   functionality on this device.

Install via Web-Interface:
Upload the factory image to the device to the Netgear Web-Interface.
The device might asks you to confirm the update a second time due to
detecting the OpenWRT firmware as older. The device will automatically
reboot after the image is written to flash.

Install via TFTP:
Connect to the devices serial. Hit Enter-Key in bootloader to stop
autobooting. Command "fw_recovery" will start a tftp server, waiting for
a DNI image to be pushed.
Assign your computer the IP-address 192.168.1.10/24. Push image with
tftp -4 -v -m binary 192.168.1.1 -c put <OPENWRT_FACTORY>
Device will erase factory-partition first, then writes the pushed image
to flash and reboots.

Parts of this commit are based on Thomas Hebb's work on the
openwrt-devel mailinglist.

Label: eth0

phy@mdio4:
Label: eth1
gmac1

Installation instructions:
Since boards ship with old version of LEDE installation is simple.
Just use sysupgrade -n -F sysupgrade.bin

Syuspgrade needs to be forced since OpenWRT uses DT detection in recent
releases.

If you get error that FIT configuration is not found during boot it is
due to older U-boot used on your board.
That is because 8devices used custom FIT configuration partition name
as they internally had v1 and v2 boards.
Only v2 boards are sold so now they are shipping boards with never
U-boot using generic config@1 FIT partition name.

Also for old uboot it is possible to force loading config@1 by changing
uboot environment:

setenv boot5 'bootm 0x84000000#config@1’
saveenv

f5195e72c0 kernel: mtd: bcm47xxpart: improve handling TRX partition size
This is important fix for flash parsing in some corner cases. In case
of TRX subpartition with rootfs being aligned to the flash block size it
was incorrectly registered twice. Detecting & registering it as a
standalone partition was resulting in an incorrect "firmware" partition
size and possibly broken sysupgrade.

It wasn't noticed before because "rootfs" alignment depends on a kernel
size. It can happen though - depending on the configuration and the
kernel size.

bcf2125142 ramips: add support for Zorlik ZL5900V2
The Zorlik ZL5900V2 is an unbranded clone of HAME MPR-A1/2.  It is
marketed as "3G Wi-Fi Router".  Only the PCB has the model name
"ZL5900V2" printed on it.

Specifications:
- Ralink RT5350F (360 MHz)
- 32 MB RAM
- 8 MB Flash
- 802.11bgn 1T1R
- 1x 10/100 Mbps Ethernet
- 1x USB 2.0 (Type-A)
- 5200 mAh battery

The ramdisk image (not the squashfs sysupgrade image) can be flashed
through the web interface (named "GoAhead") of the factory firmware.
However, as the factory firmware does not cleanly unmount the rootfs
before flashing, the device may hang instead of rebooting after
successful write.  Power cycling the device gets you in OpenWrt where
the squashfs image may be flashed through normal sysupgrade procedure.

1680ae7eae ramips: add dwr-512 jboot firmware configuration
The previous fw version require the replacement of the stock bootloader
with u-boot. This prevent an easy stock restore of the original fw.

Now a proper fw util has been developed to manage the stock jboot
bootloader. Therefore make sense have a fw image for the stock
bootloader.

The old fw configuration (u-boot) is not compatible with the new one
and will not be supported anymore.

So at the end 2 image can be generated:

1) factory image with jboot bootloader
     openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin
2) sysupgrade image with jboot bootloader

57c641ba6e ar71xx: rework chipidea controller support, add QCA9531
Rework (again) platform support for dual-role chipidea USB controller:

- include support for QCA9531
- use correct EHCI block size
- drop ar933x_usb_setup_ctrl_config() function
- simplify code after previous "register chipidea only in device mode"
  change (fa22714181)

Reworked patch was tested on devices with below QCA WiSOCs (signal/GPIO
name with required bootstrap state for USB bus 0 in device mode):

- AR9331  (GPIO13 pull-down)
- AR9342  (RGMII_TXD1/ETXD1 pull-up)
- AR9344  (GPIO20 pull-up)
- QCA9531 (GPIO13 pull-up)
- QCA9558 (GPIO13 pull-up)

The only way to select device mode for bus 0 is to change SOC bootstrap
configuration which is sampled only once, at hard reset. Likely, other
models, like QCA9556 or AR9341, should also support dual-role USB mode
but they were not tested.

D-Link DAP-1330 rev. A1 is a wall-plug N300 Wi-Fi range extender,
based on Qualcomm/Atheros QCA9533 v2.

Short specification:

- 650/393/216 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 64 MB of RAM (DDR1)
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 2x external antennas
- 6x LED (2 are bi-color), 2x button
- 4 pin on pcb (looking from eth port and from left to right tx,rx,gnd,vcc)

Flash instruction: use "factory" image directly in vendor GUI.

This device has a recovery system that assign the ip addr of env
variable "serverip" via dhcp to a pc, and the "ipaddr" value to itself.
The recovery it's triggered by a not bootable firmware,
or pressing the reset button during the bootloader startup (first 30 seconds).
The recovery uses a http page to restore the firmware, and it's checking
the firmware image header, so use the "factory" image to
restore or the original firmware.

You can access vendor firmware over serial using:
- login: root
- password: linuxrocks

Image was tested only in EU version of the device, but should work
also with the same device version sold in other countries.

  * UART header on PCB (57600 8n1)
  * 6x LED (GPIO-controlled)
  * 1x bi-color Signal Strength LED (GPIO-controlled)
  * 2x button
  * JBOOT bootloader

Installation:
Apply factory image via d-link http web-gui.

How to revert to OEM firmware:
1.) Push the reset button and turn on the power. Wait until LED start
    blinking (~10sec.)
2.) Upload original factory image via JBOOT http (IP: 192.168.123.254)
3.) If http doesn't work, it can be done with curl command:
    curl -F FN=@XXXXX.bin http://192.168.123.254/upg
    where XXXXX.bin is name of firmware file.

6525bffc0a ramips: add support for DLINK DWR-921-C1
The DWR-921-C1 Wireless Routers with LTE embedded modem is based on the
MT7620N SoC.

Specification:

  * MediaTek MT7620N (580 Mhz)
  * 64 MB of RAM
  * 16 MB of FLASH
  * 802.11bgn radio
  * 5x 10/100 Mbps Ethernet (1 WAN and 4 LAN)
  * 2x external, detachable (LTE) antennas
  * UART header on PCB (57600 8n1)
  * 6x LED (GPIO-controlled)
  * 1x bi-color Signal Strength LED (GPIO-controlled)
  * 2x button
  * JBOOT bootloader

The status led has been assigned to the dwr-921-c1:green:sigstrength (lte
signal strength) led. At the end of the boot it is switched off and is
available for lte operation. Work correctly also during sysupgrade
operation.

Installation:
Apply factory image via d-link http web-gui.

How to revert to OEM firmware:
1.) Push the reset button and turn on the power. Wait until LED start
    blinking (~10sec.)

ace1686200 ramips: mt7620: eMMC: stop invalid memory access if only one device is defined
pdev->id is -1 when only one device exists, and is used:
* as an index into drv_mode[] to determine whether to use
  PIO or DMA mode (via host->id)
* as an index into msdc_6575_host[], to store the
  mmc_priv() data.

Obviously, -1 is not a valid index in either case, causing
us to read invalid memory, and memory corruption,
respectively.

The invalid memory read is causing non-deterministic
behaviour, in particular in the v4.4 kernel it still
picked DMA mode, but in the v4.9 it now always picks
PIO mode.
Also, PIO mode doesn't work, causing the following:

/ # echo 3 > /proc/sys/vm/drop_caches
[ 3845.249237] sh (128): drop_caches: 3

/ # /root/usr/lib/libc.so
[ 3846.096070] do_page_fault(): sending SIGSEGV to libc.so for invalid read access from 7f9cb5a0
[ 3846.104758] epc = 779b0ea4 in libc.so[7792f000+c3000]
[ 3846.109907] ra  = 779a8004 in libc.so[7792f000+c3000]
Segmentation fault

/ # /root/usr/lib/libc.so
musl libc (mipsel-sf)
Version 1.1.16-git-40-g54807d47
Dynamic Program Loader
Usage: /root/usr/lib/libc.so [options] [--] pathname [args]

(i.e. initial page-in of any binary causes a segfault,
subsequent access works.)

While this change doesn't fix PIO mode, it at least makes
us deterministically use DMA (which works), and it also
stops us from corrupting memory.
