24043a0d2e ramips: add support for TP-Link TL-WR840N v4 and TL-WR841N v13
TP-Link TL-WR840N v4 and TL-WR841N v13 are simple N300 routers with
5-port FE switch and non-detachable antennas. Both are very similar
and are based on MediaTek MT7628NN (aka MT7628N) WiSoC.

The difference between these two models is in number of available
LEDs, buttons and power input switch.

This work is partially based on GitHub PR#974.

Specification:

- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- TL-WR840N v4: 5x LED (GPIO-controlled), 1x button
- TL-WR841N v13: 8x LED (GPIO-controlled*), 2x button, power input
  switch

* WAN LED in TL-WR841N v13 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 green part of the LED.

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 ("0x4"/"0x13" for these devices) but it seems
that anything other than "0" is correct.

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.

Tests showed that the GUI upgrade routine copies value of "Additional
Hardware Version" from existing firmware into offset "0x2023c" in
provided file, _before_ storing it in flash. In case of vendor firmware
upgrade files (which all include U-Boot image and two headers), this
offset points to the matching field in kernel+rootfs firmware part
header. Unfortunately, in case of LEDE factory image file which contains
only one header, it points to the offset "0x2023c" in kernel image. This
leads to a corrupted kernel and ends up with a "soft-bricked" device.

The good news is that U-Boot in these devices contains well known tftp
recovery mode, which can be triggered with "reset" button. What's more,
in comparison to some of older MediaTek based TP-Link devices, this
recovery mode doesn't write whole file at offset "0x0" in flash, without
verifying provided file in advance. In case of recovery mode in these
devices, first "0x20000" bytes are always skipped and "0x7a0000" bytes
from rest of the file are stored in flash at offset "0x20000".

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:

1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "lede-ramips-mt7628-tl-wr84...-squashfs-tftp-recovery.bin"
   to "tp_recovery.bin" and place it in tftp server directory.
3. 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.
4. Router will download file from server, write it to flash and reboot.

To access U-Boot CLI, keep pressed "4" key during boot.

4b35e174ca firmware-utils: mktplinkfw2: support additional hardware version
As it turned out, some of new MediaTek based TP-Link devices use value
from field at 0x3c offset in version 3 of TP-Link header to specify
"Additional Hardware Version".

Value from this field is validated during regular (GUI) firmware upgrade
on devices like TL-WR840N v4 or TL-WR841N v13. If it's zero (based on
some tests, it seems that firmware will accept anything != 0), errors
like below are printed on console and upgrade fails:

[ rsl_sys_updateFirmware ] 2137:  Firmware Additional HardwareVersion
check failed

b05c7193fd ar71xx: add support for TP-Link Archer C58 v1
TP-Link Archer C58 v1 is a dual-band AC1350 router, based on Qualcomm
QCA9561 + QCA9886. It looks like Archer C59 v1 without USB port.

Specification:

- 775/650/258 MHz (CPU/DDR/AHB)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH (SPI NOR)
- 3T3R 2.4 GHz
- 2T2R 5 GHz
- 5x 10/100 Mbps Ethernet
- 6x LED, 3x button
- UART header on PCB, RX, TX at TP4+5 (backside)

QCA9886 wlan needs pre_cal_data file and enable ieee80211 phy hotplug to
patch macaddress.

Flash instruction:

Use "factory" image directly in vendor GUI.

Recovery method:

1. Set PC to fixed ip address 192.168.0.66/24.
2. Download "lede-ar71xx-generic-archer-c58-v1-squashfs-factory.bin" and
   rename it to "tp_recovery.bin".
3. Start a tftp server with the file "tp_recovery.bin" in its root
   directory.
4. Turn off the router.
5. Press and hold Reset button.
6. Turn on router with the reset button pressed and wait ~15 seconds.
7. Release the reset button and after a short time the firmware should
   be transferred from the tftp server.
8. Wait ~30 second to complete recovery.

Flash instruction under U-Boot, using UART:

tftp 0x81000000 lede-ar71xx-...-sysupgrade.bin
erase 0x9f020000 +$filesize
cp.b $fileaddr 0x9f020000 $filesize

9fec39a033 ar71xx: add support for TP-Link TL-WA855RE v1
TP-Link TL-WA855RE v1 is a wall-plug N300 Wi-Fi range extender,
based on Qualcomm/Atheros QCA9533 v2.

Short specification:

- 550/397/198 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 32 MB of RAM (DDR1)
- 4 MB of FLASH
- 2T2R 2.4 GHz
- 2x external antennas
- 2x LED (green and orange in the same package), 2x button
- UART: TP5(TX) and TP4(RX) test points on PCB

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

Warning: this device does not include any kind of recovery mechanism
in the bootloader and disassembling process is not trivial.

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

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

Migrate Arduino Yun from legacy to generic building code.

necessary as kernel > 4.4 with default LEDE configuration grows
bigger.

To use the new partitioning, you need to update your U-Boot env in
advance:

setenv mtdparts "spi0.0:256k(u-boot)ro,64k(u-boot-env),15936k(firmware),64k(nvram),64k(art)ro"

* Fixes an unlimited overread of heap-based buffers in mbedtls_ssl_read()
* Adds exponent blinding to RSA private operations
* Wipes stack buffers in RSA private key operations (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt())
* Removes SHA-1 and RIPEMD-160 from the default hash algorithms for certificate verification.
* Fixes offset in FALLBACK_SCSV parsing that caused TLS server to fail to detect it sometimes.
* Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a potential Bleichenbacher/BERserk-style attack.

6adc757097 apm821xx: MR24: fix ethernet phy detection on the MR24
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
This patch fixes a problem where the AR8035 PHY can't be
detected on the Cisco Meraki MR24, when the ethernet cable
is not connected during boot.

Russell Senior reported:
|This appears to be a problem during probing of the AR8035
|phy chip. When ethernet has no link, the phy detection fails,
|and eth0 is not created. Plugging ethernet later has no effect,
|because there is no interface as far as the kernel is
|concerned. The relevant part of the boot log looks like this:
|
|[    0.876611] /plb/opb/emac-rgmii@ef601500: input 0 in RGMII mode
|[    0.882532] /plb/opb/ethernet@ef600c00: reset timeout
|[    0.888546] /plb/opb/ethernet@ef600c00: can't find PHY!
