ed43a4d4ac sunxi: backport the stmmac driver from kernel 4.13
This adds support for the GMAC which is use in the A64 and other
Allwinner chips by backporting the changes from the kernel versions
4.13.

Some commits are not backported which are adding support for newly
introduced APIs which are not available in kernel 4.9.

f2107fc328 ramips: improve Xiaomi Mi Router 3G support
This commit improves support for the Xiaomi Mi Router 3G originally
added in commit 6e283cdc0d

Improvements:

- Remove software watchdog as hardware watchdog now working as per
  commit 3fbf3ab44f for all mt7621
  devices.

- Reset button polarity corrected - length of press determines reboot
  (short press) vs. reset to defaults (long press) behaviour.

- Enable GPIO amber switch port LEDs on board rear - lit indicates 1Gbit
  link and blink on activity.  Green LEDs driven directly by switch
  indicating any link speed and tx activity.

- USB port power on/off GPIO exposed as 'usbpower'

- Add access to uboot environment settings for checking/setting uboot
  boot order preference from user space.

Changes:

- Front LED indicator is physically made of independent Yellow/Amber,
  Red & Blue LEDs combined via a plastic 'lightpipe' to a front panel
  indicator, hence the colour behaviour is similar to an RGB LED. RGB
  LEDs are not supported at this time because they produce colour results
  that do not then match colour labels, e.g. enabling 'mir3g:red' and
  'mir3g:blue' would result in a purple indicator and we have no such
  label for purple.
  The yellow, red & blue LEDs have been split out as individual yellow,
  red & blue status LEDs, with yellow being the default status LED as
  before and with red's WAN and blue's USB default associations removed.

- Swapped order of vlan interfaces (eth0.1 & eth0.2) to match stock vlan
  layout. eth0.1 is LAN, eth0.2 is WAN

- Add 'lwlll' vlan layout to mt7530 switch driver to prevent packet
  leakage between kernel switch init and uci swconfig

uboot behaviour & system 'recovery'

uboot expects to find bootable kernels at nand addresses 0x200000 &
0x600000 known by uboot as "system 1" and "system 2" respectively.
uboot chooses which system to hand control to based on 3 environment
variables: flag_last_success, flag_try_sys1_failed & flag_try_sys2_failed

last_success represents a preference for a particular system and is set
to 0 for system 1, set to 1 for system 2.  last_success is considered *if*
and only if both try_sys'n'_failed flags are 0 (ie. unset) If *either*
failed flags are set then uboot will attempt to hand control to the
non failed system. If both failed flags are set then uboot will check
the uImage CRC of system 1 and hand control to it if ok.  If the uImage
CRC of system is not ok, uboot will hand control to system 2
irrespective of system 2's uImage CRC.

NOTE: uboot only ever sets failed flags, it *never* clears them. uboot
sets a system's failed flag if that system's was selected for boot but
the uImage CRC is incorrect.

Fortunately with serial console access, uboot provides the ability to
boot an initramfs image transferred via tftp, similarly an image may
be flashed to nand however it will flash to *both* kernels so a backup
of stock kernel image is suggested. Note that the suggested install
procedure below set's system 1's failed flag (stock) thus uboot ignores
the last_success preference and boots LEDE located in system 2.

Considerable thought has gone into whether LEDE should replace both
kernels, only one (and which one) etc. LEDE kernels do not include a
minimal rootfs and thus unlike the stock kernel cannot include a
method of controlling uboot environment variables in the event of
rootfs mount failure. Similarly uboot fails to provide an external
mechanism for indicating boot system failure.

Installation - from stock.

Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
  lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
  from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
  wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: nvram set flag_try_sys1_failed=1
- run: nvram commit
- run: reboot

Recovery - to stock.

Assuming you used the above installation instructions you will have a
stock kernel image in system 1. If it can be booted then it may be used
to perform a stock firmware recovery, thus erasing LEDE completely. From
a 'working' LEDE state (even failsafe)

Failsafe only:
- run: mount_root
- run: sh /etc/uci-defaults/30_uboot-envtools
Then do the steps for 'All'

All:
- run: fw_setenv flag_try_sys2_failed 1
- run: reboot

The board will reboot into system 1 (stock basic kernel) and wait with
system red light slowly blinking for a FAT formatted usb stick with a
recovery image to be inserted.  Press and hold the reset button for
around 1 second. Status LED will turn yellow during recovery and blue
when recovery complete.

9c500db896 ramips: fix used MAC addresses for Phicomm K2P
The factory partition of the Phicomm K2P contains two MAC addresses.
The lower MAC address is at offset 0xe006 and the higher one is at
offset 0xe000.

Use the lower MAC address as base mac-address which the switch driver
increments by one for the second (wan) vlan.

The MAC addresses are still inverted in contrast to the stock firmware
where the lower MAC address is used for wan. But at least the use of a
MAC address not intended/reserved for this particular board is fixed.

133815ad8f ramips: fix D240 mini-PCIe power control GPIOs
In commit b11c51916c ("ramips: Improve Sanlinking D240 config") I made
a mistake with regards GPIO numbering. And in addition to specifying the
wrong GPIO for controling the power of one of the mini-PCIe, I recently
discovered that the power of both slots can be controlled.

This patch specifies the correct GPIO for the left-most mini-PCIe slot
of the D240 (labeled power_mpcie2 since the slot is attached to SIM2),
and adds a GPIO that can be used to control the power of the other
mini-PCIe slot (labeled power_mpcie1).

161a3be5ad ramips: add support for TP-Link Archer C20 v1
TP-Link Archer C20 v1 is a router with 5-port FE switch and
non-detachable antennas. It's very similiar to TP-Link Archer C50.
Also it's based on MediaTek MT7620A+MT7610EN.

Specification:
- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 8x LED (GPIO-controlled*), 2x button, power input switch
- 1 x USB 2.0 port

* WAN LED in this devices is a dual-color, dual-leads type which isn't
  (fully) supported by gpio-leds driver. This type of LED requires both
  GPIOs state change at the same time to select color or turn it off.
  For now, we support/use only the blue part of the LED.
* MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't
  work.

Factory image notes:

These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device.

We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash. So, to flash this device we must
to prepare image using original firmware from tp-link site with uboot.

Flash instruction:

Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot.
There are two ways to flash the device to LEDE:

1) Using tftp mode with UART connection and original LEDE image

 - Place lede-ramips-mt7620-ArcherC20-squashfs-factory.bin in tftp
   server directory
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - Connect PC with one of LAN ports, power up the router and press
   key "4" to access U-Boot CLI.
 - Use the following commands to update the device to LEDE:

    setenv serverip 192.168.0.66
    tftp 0x80060000 lede-ramips-mt7620-ArcherC20-squashfs-factory.bin
    erase tplink 0x20000 0x7a0000
    cp.b 0x80060000 0x20000 0x7a0000
    reset

 - After that the device will reboot and boot to LEDE

2) Using tftp mode without UART connection but require some
   manipulations with target image

 - Download and unpack TP-Link Archer C20 v1 firmware from original web
   site
 - Split uboot.bin from original firmware by this command (example):

    dd if=Archer_C20v1_0.9.1_4.0_up_boot(160427)_2016-04-27_13.53.59.bin of=uboot.bin bs=512 count=256 skip=1

 - Create ArcherC20V1_tp_recovery.bin using this command:

    cat uboot.bin lede-ramips-mt7620-ArcherC20-squashfs-factory.bin > ArcherC20V1_tp_recovery.bin

 - Place ArcherC20V1_tp_recovery.bin in tftp server directory.
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - Connect PC with one of LAN ports, press the reset button, power up
   the router and keep button pressed for around 6-7 seconds, until
   device starts downloading the file.
 - Router will download file from server, write it to flash and reboot.

eff3549c58 generic: drop support for get_port_stats() on ar8xxx
The implementation is not efficient on ar8xxx switches. It triggers high
CPU load and degrades device performance.

The high CPU load has been traced down to the ar8xxx_reg_wait() call in
ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set
by the request to update the MIB counter is cleared.

This commit removes the get_port_stats() code introduced in 4d8a66d and
leaves a note for future hacker's beware.

Fixes: FS#1004
