b5dd746cbb ramips: add support for D-Link DIR-2660 A1
This patch adds support for D-Link DIR-2660 A1.

Specifications:
* Board: AP-MTKH7-0002
* SoC: MediaTek MT7621AT
* RAM: 256 MB (DDR3)
* Flash: 128 MB (NAND)
* WiFi: MediaTek MT7615N (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 2.0, 1 USB 3.0
* Buttons: Reset, WPS
* LEDs: Power (white/orange), Internet (white/orange), WiFi 2.4G (white),
        WiFi 5G (white), USB 3.0 (white), USB 2.0 (white)

Notes:
* WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips

Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
  button, then re-plug it. Keep the reset button pressed until the power
  LED starts flashing orange, manually assign a static IP address under
  the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

* Some modern browsers may have problems flashing via the Recovery GUI,
  if that occurs consider uploading the firmware through cURL:

    curl -v -i -F "firmware=@file.bin" 192.168.0.1

MAC addresses:

lan   factory 0xe000     *:a7 (label)
wan   factory 0xe006     *:aa
2.4   factory 0xe000 +1  *:a8
5.0   factory 0xe000 +2  *:a9

Seems like vendor didn't replace the dummy entries in the calibration data.

45a81f7056 ramips: add support for HooToo HT-TM05
The HooToo HT-TM05 is a battery powered router, with an Ethernet and USB port.
Vendor U-Boot limited to 1.5 MB kernel size, so use lzma loader (loader-okli).

Specifications:

  SOC:     MediaTek MT7620N
  BATTERY: 10400mAh
  WLAN:    802.11bgn
  LAN:     1x 10/100 Mbps Ethernet
  USB:     1x USB 2.0 (Type-A)
  RAM:     64 MB
  FLASH:   GigaDevice GD25Q64, Serial 8 MB Flash, clocked at 50 MHz
           Flash itself specified to 80 MHz, but speed limited by mt7620 SPI
           fast-read enabled (m25p)
  LED:     Status LED (blue after boot, green with WiFi traffic
           4 leds to indicate power level of the battery (unable to control)
  INPUT:   Power, reset button

MAC assignment based on vendor firmware:

  2.4 GHz    *:b4   (factory 0x04)
  LAN/label  *:b4   (factory 0x28)
  WAN        *:b5   (factory 0x2e)

Tested and working:

 - Ethernet
 - 2.4 GHz WiFi (Correct MAC-address)
 - Installation from TFTP (recovery)
 - OpenWRT sysupgrade (Preserving and non-preserving), through the usual
   ways: command line and LuCI
 - LEDs (except as noted above)
 - Button (reset)
 - I2C, which is needed for reading battery charge status and level
 - U-Boot environment / variables (from U-Boot, and OpenWrt)

Installation:

 - Download the needed OpenWrt install files, place them in the root
   of a clean TFTP server running on your computer. Rename the files as,
   - ramips-mt7620-hootoo_tm05-squashfs-kernel.bin => kernel
   - ramips-mt7620-hootoo_tm05-squashfs-rootfs.bin => rootfs
 - Plug the router into your computer via Ethernet
 - Set your computer to use 10.10.10.254 as its IP address
 - With your router shut down, hold down the power button until the first
   white LED lights up.
 - Push and hold the reset button and release the power button. Continue
   holding the reset button for 30 seconds or until it begins searching
   for files on your TFTP server, whichever comes first.
 - The router (10.10.10.128) will look for your computer at 10.10.10.254
   and install the two files. Once it has finished installation, it will
   automatically reboot and start up OpenWrt.
 - Set your computer to use DHCP for its IP address

Notes:

 - U-Boot environment can be modified, u-boot-env is preserved on initial
   install or sysupgrade
 - mtd-concat functionality is included, to leave a "hole" for u-boot-env,
   combining the OEM kernel and rootfs partitions

I would like to thank @mpratt14 and @xabolcs for their help getting the
lzma loader to work!

cac9e3e2cb ramips: lzma-loader: make FLASH_START configurable
FLASH_START is supposed to point at the memory area where NOR flash are
mapped. We currently have an incorrect FLASH_START copied from ar71xx
back then and the loader doesn't work under OKLI mode.
On ramips, mt7621 has it's flash mapped to 0x1fc00000 and other SoCs
uses 0x1c000000. This commit makes FLASH_START a configurable value to
handle both cases.

51b653de94 ramips: add support for Wavlink WL-WN531A6
This patch adds support for Wavlink WL-WN531A6 (Quantum D6).

Specifications:
--------------

* SoC: Mediatek MT7621AT 2C2T, 880MHz
* RAM: 128MB DDR3, Nanya NT5CB64M16GP-EK
* Flash: 16MB SPI NOR flash, GigaDevice GD25Q127CSIG
* WiFi 5GHz: Mediatek MT7615N (4x4:4) on mini PCIE slot.
* WiFi 2.4GHz: Mediatek MT7603EN (2x2:2) on mini PCIE slot.
* Ethernet: MT7630, 5x 1000Base-T
* LED: Power, WAN, LAN(x4), WiFi, WPS, dual color
       "WAVLINK" LED logo on the top cover.
* Buttons: Reset, WPS, "Turbo", touch button on the top
           cover via RH6015C touch sensor.
* UART: UART1: serial console (57600 8n1) on the J4 header
               located below the top heatsink.
        UART2: J12 header, located on the right side of
               the board.
* USB: One USB3 port.
* I2C: J9 header, located below the top heatsink.

Backup the OEM Firmware:
-----------------------

There isn't any firmware released for the WL-WN531A6 on
the Wavlink web site. Reverting back to the OEM firmware is
not possible unless we have a backup of the original OEM
firmware.

The OEM firmware is stored on /dev/mtd4 ("Kernel").

  1) Plug a FAT32 formatted USB flash drive into the USB port.
  2) Navigate to "Setup->USB Storage". Under the "Available
     Network folder" you can see part of the mount point of
     the newly mounted flash drive filesystem - e.g "sda1".
     The full mount point is prefixed with "/media", so in
     this case the mount point becomes "/media/sda1".
  3) Go to http://192.168.10.1/webcmd.shtml .
  4) Type the following line in the "Command" input box:

     dd if=/dev/mtd4ro of=/media/sda1/firmware.bin

  5) Click "Apply"
  6) After few seconds, in the text area should appear this
     output:

        30080+0 records in
      30080+0 records out

  7) Type "sync" in the "Command" input box and click "Apply".
  8) At this point the OEM firmware is stored on the flash
     drive as "firmware.bin". The size of the file is 15040 KB.

Installation:
------------

* Flashing instructions (OEM web interface):
The OEM web interface accepts only files with names containing
"WN531A6". It's also impossible to flash the *-sysupgrade.bin
image, so we have to flash the *-initramfs-kernel.bin first and
use the OpenWrt's upgrade interface to write the sysupgrade
image.

  1) Rename openwrt-ramips-mt7621-wavlink_wl-wn531a6-initramfs-kernel.bin
     to WN531A6.bin.
  2) Connect your computer to the one of the LAN ports of the
     router with an Ethernet cable and open http://192.168.10.1
  3) Browse to Setup -> Firmware Upgrade interface.
  4) Upload the (renamed) OpenWrt image - WN531A6.bin.
  5) Proceed with the firmware installation and give the device
     a few minutes to finish and reboot.
  6) After reboot wait for the "WAVLINK" logo on the top cover
     to turn solid blue, and open http://192.168.1.1
  7) Use the OpenWrt's "Flash Firmware" interface to write the
     OpenWrt sysupgrade image:
     openwrt-ramips-mt7621-wavlink_wl-wn531a6-squashfs-sysupgrade.bin

* Flashing instructions (u-boot TFTP):
  1) Configure a TFTP server on your computer and set its IP
     to 192.168.10.100
  2) Rename the OpenWrt sysupgrade image to firmware.bin and
     place it in the root folder of the TFTP server.
  3) Power off the device and connect an Ethernet cable from
     one of its LAN ports your computer.
  4) Press the "Reset" button (and keep it pressed)
  5) Power on the device.
  6) After a few seconds, when the connected port LAN LED stops
     blinking fast, release the "Reset" button.
  7) Flashing OpenWrt takes less than a minute, system will
     reboot automatically.
  8) After reboot the WAVLINK logo on the top cover will indicate
     the current OpenWrt running status (wait until the logo tunrs
     solid blue).

Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
  Follow "Flashing instructions (u-boot TFTP)" and use the
  "firmware.bin" backup image.

* OpenWrt "Flash Firmware" interface:
  Upload the "firmware.bin" backup image and select "Force update"
  before continuing.

Notes:
-----
* The MAC address shown on the label at the back of the device
is assigned to the 2.4G WiFi adapter.

  MAC addresses assigned by the OEM firmware:
  2.4G: *:XX (label): factory@0x0004
    5G: *:XX + 1    : factory@0x8004
   WAN: *:XX - 1    : factory@0xe006
   LAN: *:XX - 2    : factory@0xe000

* The I2C bus and UART2 are fully functional. The headers are
not populated.

adf830a3a5 ramips: remove further mt7621 code from local ethernet driver
While commit 734a8c46e7 focussed on removing stuff directly
selected by the NET_RALINK_* symbols, this patch removes additional
unused mt7621-specific code from the ethernet driver.

As with the previous patch, the main reason is to reduce the amount
of code we have to maintain and care about.

Note that this patch still keeps a few lines with
IS_ENABLED(CONFIG_SOC_MT7621) in mtk_eth_soc.h/.c, as this file is
still selected for the mt7621 subtarget.

734a8c46e7 ramips: remove legacy ethernet driver components for mt7621
The mt7621 subtarget has been switched to DSA quite a while ago and
seems to run sufficiently fine. Build with older kernels than 5.4 has
been disabled directly during the kernel bump, so our local ethernet
driver is unused in master since then.

Therefore, let's remove the mt7621-specific parts of "our" ethernet
driver, so we don't have to maintain them and it's obvious to
everybody that they are not used anymore.

This also drops the offloading components as this was specifically
implemented to depend on mt7621.

74438d5419 ramips: add support for MikroTik RouterBOARD 760iGS (hEX S)
This patch adds support for the MikroTik RouterBOARD 760iGS router.
It is similar to the already supported RouterBOARD 750Gr3.
The 760iGS device features an added SFP cage, and passive
PoE out on port 5 compared to the RB750Gr3.

https://mikrotik.com/product/hex_s

Specifications:

- SoC: MediaTek MT7621A
- CPU: 880MHz
- Flash: 16 MB
- RAM:  256 MB
- Ethernet: 5x 10/100/1000 Mbps
- SFP cage
- USB port
- microSD slot

Unsupported:

- Beeper (requires PWM driver)
- ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1)
  The linux driver requires an interrupt, and pendown GPIO
  These are unknown, and not needed with the touchscreen
  only used for temperature and voltage monitoring.
  ads7846 hwmon:
  temp0 is degrees Celsius
  temp1 is voltage * 32

GPIOs:

- 07:  input passive PoE out (lan5) compatible (Mikrotik) device connected
- 17:  output passive PoE out (lan5) switch

Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common

To boot to intramfs image in RAM:

1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
   Wait (~25 seconds) for beep and then release reset button.
   The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
   check by plugging in to port 2-5 and going to 192.168.1.1.

To install OpenWrt to flash:

1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.

OEM firmware differences:

- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.

1eac573b53 ramips: mt7621: implement compatibility version for DSA migration
This implements the newly introduced compat-version to prevent
broken upgrade between swconfig and DSA for ramips' mt7621 subtarget.

In order to make the situation more transparent for the user, and
to prevent large switch-cases for devices, it is more convenient to
have the entire subtarget 1.1-by-default. This means that new devices
will be added with 1.1 from the start, but in contrast we don't need
to switch them in board.d files. Apart from that, users that manually
backport devices to 19.07 with swconfig will have an equivalent
upgrade experience to officially supported devices.

Since DSA support on mt7621 is out for a while already, this applies
the same uci-defaults workaround for early adopters as already
done for kirkwood and mvebu in previous commits.

a40ddc2195 ramips: adjust LZMA_TEXT_START for 32MB RAM devices
Currently the lzma-loader is placed in RAM at 32MB offset, which does not
make sense for devices with only 32MB RAM. If we adjust LZMA_TEXT_START to
24MB offset, then the lzma-loader can be used on those devices and still
about 24MB memory will be available for uncompressed image, which should be
enough for most use cases.

The sbutarget has testing support for kernel 5.4 for quite a while
and builds fine, however, only one devices there is > 4 MiB.

Since it's unlikely to get a Tested-by for that device, and the other
ralink subtargets appear to be working with 5.4 so far, let's set
this target to 5.4 by default as well.

That way, even if the device happens to break, we'll still have at

121c021989 ramips: invert wpad selection for mt7621
For ramips/mt7621, the wpad-basic package is not selected by default,
but added for every device individually as needed.

While this might be technically correct if the SoC does not come with
a Wifi module, only 18 of 97 devices for that platform are set up
_without_ wpad-basic currently.

Therefore, it seems more convenient to add wpad-basic by default for
the subtarget and then just remove it for the 18 mentioned devices,
instead of having to add it for about 60 times instead.

This would also match the behavior of the 5 other subtargets, where
wpad-basic/wpad-mini is added by default as well, and thus be more
obvious to developers without detailed SoC knowledge.

a673ac66fa ramips: add support for Netgear JWNR2010 v5
Specification:
 - CPU: MediaTek MT7620N (580 MHz)
 - Flash size: 4 MB NOR SPI
 - RAM size: 32 MB DDR1
 - Bootloader: U-Boot
 - Wireless: MT7620N 2x2 MIMO 802.11b/g/n (2.4 GHz)
 - Switch: MT7620 built-in 10/100 switch with vlan support
 - Ports: 4x LAN, 1x WAN
 - Others: 7x LED, Reset button, UART header on PCB (57600 8N1)

Flash instructions:
 1. Use ethernet cable to connect router with PC/Laptop, any router
    LAN port will work.
 2. To flash openwrt we are using nmrpflash[1].
 3. Flash commands:
      First we need to identify the correct Ethernet id.

        nmrpflash -L

        nmrpflash -i net* -f openwrt-ramips-mt7620-netgear_jwnr2010-v5-squashfs-factory.img

      This will show something like "Advertising NMRP server on net*..." (net*, *=1,2,3... etc.)

 4. Now remove the power cable from router back side and immediately connect it again.
    You will see flash notification in CMD window, once it says reboot the device just
    plug off the router and plug in again.

Revert to stock:
 1. Download the stock firmware from official netgear support[2].
 2. Follow the same nmrpflash procedure like above, this time just use the stock firmware.

        nmrpflash -i net* -f N300-V1.1.0.54_1.0.1.img

MAC addresses on stock firmware:
LAN = *:28 (label)
WAN = *:29
WLAN = *:28

On flash, the only valid MAC address is found in factory 0x4.

Special Note:
 This openwrt firmware will also support other netgear N300 routers like below as they
 share same stock firmware[3].
 JNR1010v2 / WNR614 / WNR618 / JWNR2000v5 / WNR2020 / WNR1000v4 / WNR2020v2 / WNR2050

77e850fe76 ramips: tidy up MAC address setup for Linkit Smart and Omega2
Linkit Smart 7688 and Onion Omega 2(+) are one-port devices, and
have their port set to LAN by default. Setting up a WAN MAC address
for them doesn't make any sense, as no wan interface will be created
in uci config. Despite, these devices also set lan_mac in 02_network,
although mtd-mac-address sets a different address for the ethernet
interface in DTS.

Clean this up by moving the lan_mac value into DTS and dropping the
entries in 02_network completely. That way, the effective address
on the LAN interface should stay the same, but we get rid of the
extra (re)assignments.

As I don't have access to the devices, this does not tell anything
about whether 0x2e is actually a good choice, it just preserves
the existing assignment.

009e62c92c ramips: add support for TP-Link RE200 v3
TP-Link RE200 v3 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas. It's based on MediaTek MT7628AN+MT7610EN like the v2.

Specifications
--------------

- MediaTek MT7628AN (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- 8x LED (GPIO-controlled), 2x button

Unverified:
- UART header on PCB (57600 8n1)

There are 2.4G and 5G LEDs in red and green which are controlled
separately.

MAC addresses
-------------

MAC address assignment has been done according to the RE200 v2.

The label MAC address matches the OpenWrt ethernet address.

Installation
------------

Web Interface
-------------

It is possible to upgrade to OpenWrt via the web interface. Simply flash
the -factory.bin from OEM. In contrast to a stock firmware, this will not
overwrite U-Boot.

Recovery
--------

Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console.

The device has not been opened for adding support. However, it is expected
that the behavior is similar to the RE200 v2. Instructions for serial console
and recovery may be checked out in commit 6d6f36ae78 ("ramips: add support
for TP-Link RE200 v2") or on the device's Wiki page.

1deaf695ec ramips: fix/tidy up 4M tplink-v2-image flash layouts
For the TP-Link 4M devices with tplink-v2-image recipe
(mktplinkfw2.c), there are two different flash layouts based
on the size of the (u)boot partition:

device         uboot    OEM firmware  OpenWrt (incl. config)
tl-wr840n-v5   0x20000  0x3c0000      0x3d0000
tl-wr841n-v14  0x10000  0x3d0000      0x3e0000

In both cases, the 0x10000 config partition is used for the firmware
partition as well due to the limited space available and since it's
recreated by the OEM firmware anyway.

However, the TFTP flashing process will only copy data up to the
size of the initial (OEM) firmware size. Therefore, while we can
use the bigger partition to have additional erase blocks on the
device, we have to limit the image sizes to the TFTP limits.

So far, only one layout definition has been set up in mktplinkfw2.c
for 4M mediatek devices. This adds a second one and assigns them
to the devices so the image sizes are correctly restrained.

the DIR-1760/2660 A1, this patch also introduces a common DTSI which can
be shared with these devices, with support to be added in future commits.

Specifications:
* Board: AP-MTKH7-0002
* SoC: MediaTek MT7621AT
* RAM: 256 MB (DDR3)
* Flash: 128 MB (NAND)
* WiFi: MediaTek MT7615N (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WPS
* LEDs: Power (white/orange), Internet (white/orange), WiFi 2.4G (white),
        WiFi 5G (white), USB 3.0 (white)

Notes:
* WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips

Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
  button, then re-plug it. Keep the reset button pressed until the power
  LED starts flashing orange, manually assign a static IP address under
  the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

* Some modern browsers may have problems flashing via the Recovery GUI,
  if that occurs consider uploading the firmware through cURL:

    curl -v -i -F "firmware=@file.bin" 192.168.0.1

MAC addresses:

lan   factory 0xe000     *:EB (label)
wan   factory 0xe006     *:EE

The Winstars WS-WN583A6 is a wireless repeater with 2 gigabit ethernet
ports. Even if mine is branded as "Gemeita AC2100", the sticker on the
back says WS-WN583A6. So I will refer to it as Winstars WS-WN583A6.
Probably the real product name is the Wavlink WL-WN583A6 because of
the many references to Wavlink in the OEM firmware and bootlog.

Hardware
--------
SoC:   Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM:   128MB
FLASH: 8MB NOR (GigaDevice GD25Q64B)
ETH:   2x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
  - 2.4GHz: 1x MT7603E (2x2:2)
  - 5GHz:   1x MT7615E (4x4:4)
  - 6 internal antennas
BTN:
  - 1x Reset button
  - 1x WPS button
  - 1x ON/OFF switch (working but unmodifiable)
  - 1x Auto/Schedule switch (working but unmodifiable. Read Note #3)
LEDS:
  - 1x White led
  - 1x Red led
  - 1x Amber led
  - 1x Blue led
  - 2x Blue leds (lan and wan port status: working but unmodifiable)
UART:
  - 57600-8-N-1

Everything works correctly.

Currently there is no firmware update available. Because of this, in
order to restore the OEM firmware, you must firstly dump the OEM
firmware from your router before you flash the OpenWrt image.

Backup the OEM Firmware
-----------------------
The following steps are to be intended for users having little to none
experience in linux. Obviously there are many ways to backup the OEM
firmware, but probably this is the easiest way for this router.
Procedure tested on M83A6.V5030.191210 firmware version.

1) Go to http://192.168.10.1/webcmd.shtml

2) Type the following line in the "Command" input box:
	mkdir /etc_ro/lighttpd/www/dev; for i in /dev/mtd*ro; do dd if=${i} of=/etc_ro/lighttpd/www${i}; done

3) Click "Apply"

   Excluding the "X.XXXXXX seconds" part, you should get the same
   exact output. If your output doesn't match mine, stop reading
   and ask for help in the forum.

5) Open the following links to download the partitions of the OEM FW:
	http://192.168.10.1/dev/mtd0ro
	http://192.168.10.1/dev/mtd1ro
	http://192.168.10.1/dev/mtd2ro
	http://192.168.10.1/dev/mtd3ro
	http://192.168.10.1/dev/mtd4ro

   If one (or more) of these files weight 0 byte, stop reading and ask
   for help in the forum.

6) Store these downloaded files in a safe place.

7) Reboot your router to remove any temporary file from your router.

Installation
------------
Flash the initramfs image in the OEM firmware interface.
When openwrt boots, flash the sysupgrade image otherwise you won't be
able to keep configuration between reboots.

Restore OEM Firmware
--------------------
Flash the "mtd4ro" file you previously backed-up directly from LUCI.
Warning: Remember to not keep settings!
Warning2: Remember to force the flash.

Notes
-----
1) The "System Command" page allows to run every command as root.
   For example you can use "dd" and "nc" to backup the OEM firmware.
   PC (SERVER):
	nc -l 5555 > ./mtdXro
   ROUTER (CLIENT):
	dd if=/dev/mtdXro | nc PC_IP_ADDRESS 5555

2) The OEM web interface accepts only images containing the string
   "WN583A6" in the filename.
   Currently the OEM interface accepts only the initramfs image
   probably because it checks if the ih_size in the image header is
   equal to the whole image size (instead of the kernel size)

   https://forum.openwrt.org/t/support-for-strong-1200/22768/19

3) The white led (namely "Smart Night Light") can be controller by the
   user only if the side switch is set to "Schedule" otherwise it will
   be activated by the light condition (there is a photodiode on the
   top side of the router)

4) Router mac addresses:

   LAN		XX:XX:XX:XX:XX:8F
   WAN		XX:XX:XX:XX:XX:90
   WIFI 2G	XX:XX:XX:XX:XX:91
   WIFI 5G	XX:XX:XX:XX:XX:92

b057862e24 Revert "ramips: fix flash layout for TP-Link TL-WR841N v14"
This reverts commit 1623defbdb.

As already stated in the reverted patch, the OEM firmware will
properly recreate the config partition if it is overwritten by
OpenWrt.

The main reason for adding the partition was the image size
restriction imposed by the 0x3d0000 limitation of the TFTP
flashing process. Addressing this by shrinking the firmware
partition is not a good solution to that problem, though:

1. For a working image, the size of the content has to be smaller
   than the available space, so empty erase blocks will remain.

2. Conceptually, the restriction is on the image, so it makes sense
   to implement it in the same way, and not via the partitioning.
   Users could e.g. do initial flash with TFTP restriction with
   an older image, and then sysupgrade into a newer one, so TFTP
   restriction does not apply.

3. The (content) size of the recovery image is enforced to 0x3d0000
   by the tplink-v2-image command in combination with
   TPLINK_FLASHLAYOUT (flash layout in mktplinkfw2.c) anyway.

9662b9d688 ramips: switch MT7620 subtarget to 5.4
MT7620 seems to work fine with kernel 5.4. Set the default kernel
version to 5.4 to bring this to a broader audience.

Tested on Archer C2 v1 / Archer C20i
