The mt7530_{r,w}32 operation over MDIO uses 3 mdiobus operations and
does not hold a lock, which causes a race condition when multiple
threads try to access a register, they may get unexpected results.
To avoid this, handle the MDIO lock manually, and use the unlocked
__mdiobus_{read,write} in the critical section.
This fixes the "Ghost VLAN" artifact[1] in MT7530/7621 when the VLAN
operation and the swconfig LED link status poll race between each other.

Reduce spi-max-frequency for Xiaomi MI Router 4AG model
Xiaomi MI Router 4AG MTD uses two flash chips (no specific on router versions when produced from factory) - GD25Q128C and W25Q128BV.
These flash chips are capable of high frequency, but due to poor board design or manufacture process.
We are seeing the following errors in the linux kernel bootup:
`spi-nor spi0.0: unrecognized JEDEC id bytes: cc 60 1c cc 60 1c
spi-nor: probe of spi0.0 failed with error -2`
This causes the partitions not to be detected
`VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6`
Then creates a bootloop and a bricked router.
The solution to limit this race condition is to reduce the frequency from 80 mhz to 50 mhz.

The Netgear R6800 and R6700v2 devices have a Semtech SX1503 GPIO
expander controlling the device LEDs. This expander was initially
supported on 4.14, but support was lost in the transition to 5.4.
Since this driver cannot be built as a kernel module, enable it in the
kernel config for all mt7621 devices.

The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.
When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.
The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.
Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
* Back side: ETH0, PoE PD port
* Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)
Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).
Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
eth a4:2b:b0:...:88
ra0 a4:2b:b0:...:88
rai0 a4:2b:b0:...:89
Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface
Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
# tftpboot 84000000 openwrt-initramfs.bin
# bootm
Revert to stock:
Using the tplink-safeloader utility from the firmware-utils package,
TP-Link's firmware image can be converted to an OpenWrt-compatible
sysupgrade image:
$ ./staging_dir/host/bin/tplink-safeloader -B EAP235-WALL-V1 \
-z EAP235-WALLv1_XXX_up_signed.bin -o eap235-sysupgrade.bin
This can then be flashed using the OpenWrt sysupgrade interface. The
image will appear to be incompatible and must be force flashed, without
keeping the current configuration.
Known issues:
- DFS support is incomplete (known issue with MT7613)
- MT7613 radio may stop responding when idling, reboot required.
This was an issue with the ddc75ff704 version of mt76, but appears to
have improved/disappeared with bc3963764d.

Yet, it is available for download.

While the latest version of 19.07 release is usable,
the current master is unbootable on the device in a normal way.
"Normal way" installations includes:
- sysupgrade (e.g. from 19.07)
- RESET button recovery with Ron Curry's (Wingspinner) UBoot image
(10.10.10.3 + "Kernal.bin")
- RESET button recovery with original U-Boot
(10.10.10.254 + "kernel")
One could flash and boot the latest master sysupgrade image successfully
with serial access to the device. But a sysupgrade from this state still
breaks the U-Boot and soft-bricks the device.

UniElec U7621-01 is a router platform board, the smaller model of
the U7621-06.
The device has the following specifications:
- MT7621AT (880 MHz)
- 256 of RAM (DDR3)
- 16 MB of FLASH (SPI NOR)
- 5x 1 Gbps Ethernet (MT7621 built-in switch)
- 1x 2.4Ghz MT7603E
- 1x 5Ghz MT7612
- 1x miniPCIe slots (PCIe bus only)
- 1x miniSIM slot
- 1x USB 2.0 (uses the usb 3.0 driver)
- 8x LEDs (1x GPIO-controlled)
- 1x reset button
- 1x UART header (4-pins)
- 1x GPIO header (30-pins)
- 1x DC jack for main power (12 V)
The following has been tested and is working:
- Ethernet switch
- 1x 2.4Ghz MT7603E (wifi)
- 1x 5Ghz MT7612 (wifi)
- miniPCIe slots (tested with Wi-Fi cards and LTE modem cards)
- miniSIM slot (works with normal size simcard)
- sysupgrade
- reset button
Installation:
This board has no locked down bootloader. The seller can be asked to
install openwrt v18.06, so upgrades are standard sysupgrade method.
Recovery:
This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.
