mediatek: add support for WAVLINK WL-WN536AX6 Rev a

Product name: Wavlink WL-WN536AX6 Rev a "Mighty LX2"
Product link: https://www.wavlink.com/en_us/product/WL-WN536AX6.html

Specifications:
SOC: MT7986AV
RAM: 512MB DDR4
Flash: 128MB SPI NAND
Ports: 4 LAN (1G) & 1 WAN (2.5G)
WIFI: MT7976PN + MT7975N
LEDs: 8 (STATUS, WIFI, WAN, LAN1, LAN2, LAN3, LAN4, PWR)
USB: 1 (3.0)

MAC table, same as stock firmware:
LAN: 80:3F:5D:xx:xx:x1 partition "hw" at 0x44e (ASCII)
WAN: 80:3F:5D:xx:xx:x2 partition "hw" at 0x460 (ASCII)
2G: 80:3F:5D:xx:xx:x3
5G: 80:3F:5D:xx:xx:x4

* Installation with OEM WebUI:

Note: Make sure PC is connected on LAN1 port. The OEM firmware has an unknown root password and settings are kept after upgrading firmware. Therefore, a customized Openwrt firmware is needed to remove the root password on login, by adding `passwd -d root` to /etc/init.d/bootcount. The WebUI does a filename check so the customized firmware is named accordingly.

1. Download modified firmware file `WAVLINK_WN536AX6-A_M36AX6_V250320-WO-437baca-modified.bin` from https://github.com/ses1er/firmware-misc/tree/main/wavlink/wl-wn536ax6a
2. Log into WebUI on default IP: http://192.168.20.1
3. Browse to More (top menu) -> System -> Firmware Upgrade.
4. Under `Local Upgrade` section, check the device to be upgraded and upload downloaded modified firmware. Click `UPLOAD FILE`, then `APPLY`
5. Wait about 2 minutes (ignore progress bar), and browse to http://192.168.20.1. You should see LUCI login page. Username is root and no password.
6. Browse to `System -> Backup/Flash Firmware`, click on `Flash Image`, click `Browse` and locate `openwrt-mediatek-filogic-wavlink_wl-wn536ax6-a-squashfs-sysupgrade.bin` file.
7. Uncheck `Keep settings and retain the current configuration` and click `Continue`.
8. Router will now be set to IP 192.168.1.1 which is the Openwrt default.

* Installation with UART:

Note: Having UART connected while cold booting the device will result in a kernel panic when initializing wifi. I've found this workaround:
1. Power off the device and ensure UART is not connected to PC.
2. Power up the device, when lights come on, plug in UART.
3. Warm boots and soft restarts will not cause kernel panic for the duration of device being powered on. Repeat steps for subsequent cold boots.

1. Configure TFTP server with IP 192.168.1.66. Copy `openwrt-mediatek-filogic-wavlink_wl-wn536ax6a-initramfs.itb` to TFTP root.
2. Interrupt boot by pressing 0.
3. Run the following in Uboot console: `setenv serverip 192.168.1.66; setenv ipaddr 192.168.1.1; tftpboot 0x46000000 openwrt-mediatek-filogic-wavlink_wl-wn536ax6-a-initramfs.itb; bootm`
4. Transfer `openwrt-mediatek-filogic-wavlink_wl-wn536ax6-a-squashfs-sysupgrade.bin` to device:
   (`scp -O openwrt-mediatek-filogic-wavlink_wl-wn536ax6-a-squashfs-sysupgrade.bin root@192.168.1.1:/tmp/`)
5. Run the following on device: `sysupgrade -n /tmp/openwrt-mediatek-filogic-wavlink_wl-wn536ax6-a-squashfs-sysupgrade.bin`

filogic: add support for Netgear EAX17

Hardware
--------

SOC:   MediaTek MT7981
RAM:   512MB DDR4
FLASH: 128MB SPI-NAND
WIFI:  Mediatek MT7915 (integrated) 2x2 802.11ax 2.4 / 5 GHz
ETH:   Mediatek MT7981 internal 1 GbE PHY
UART:  3V3 115200 8N1 (Pinout silkscreened / Do not connect VCC)

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

1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
2. Connect the TFTP server to the EAX17. Conect to the serial console,
   interrupt the autoboot process by pressing '0' when prompted.
3. Download & Boot the OpenWrt initramfs image.

   $ tftpboot openwrt.bin
   $ bootm

4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
   using scp and install using sysupgrade.

   $ sysupgrade -n <path-to-sysupgrade.bin>

kernel: fix QE bit for Fudan Micro FM25S01A SPI-NAND

According to datasheet (http://eng.fmsh.com/nvm/FM25S01A_ds_eng.pdf)
there is no QE (Quad Enable) bit for FM25S01A flash, so remove it.

mediatek: filogic: add factory image for Asus TUF-AX4200

The initramfs.trx image can be flashed from the web interface of factory
firmware.

Unfortunately, the default boot command of the bootloader does not load
the ramdisk in the FIT image. This means that the image can only be
built when the option TARGET_ROOTFS_INITRAMFS_SEPARATE is disabled.

Tested with firmware 3.0.0.4.388_33965 (U-Boot 2022.10 / 2.0.0.5).

mediatek: filogic: increase flash speed on ASUS TUF AX6000

This commit increases the SPI bus frequency from 20 to 52 MHz. Reduces boot
time by 2s. Below is a performance comparison.

Before:
root@OpenWrt:~# dd if=/dev/mtd1 of=/dev/null bs=10M count=1 status=progress
10485760 bytes (10 MB, 10 MiB) copied, 1.68404 s, 6.2 MB/s

After:
root@OpenWrt:~# dd if=/dev/mtd1 of=/dev/null bs=10M count=1 status=progress
10485760 bytes (10 MB, 10 MiB) copied, 0.819222 s, 12.8 MB/s

Taken from PR #18752 as each device should be tested individually, so I have
created a separate PR for this.
