This commit adds OpenWrt U-Boot layout support for Routerich AX3000. The
aims:
1. Get open-source U-Boot;
2. Get maximum available free space in OpenWrt.
Install
-------
1. Copy OpenWrt ubootmod-bl31-uboot.fip, ubootmod-preloader.bin, to the
/tmp folder of the router using scp.
2. Make mtd partitions backups:
http://192.168.1.1/cgi-bin/luci/admin/system/flash -> Save mtdblock
contents
3. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
4. Write FIP and preloader:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/ubootmod-preloader.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/ubootmod-bl31-uboot.fip FIP
```
5. Copy OpenWrt ubootmod-initramfs-recovery.itb to the tftp server root
with IP 192.168.1.254.
6. Reboot router:
```
reboot
```
U-Boot will automatically download from the tftp server and boot OpenWrt
initramfs system.
7. Copy OpenWrt ubootmod-squashfs-sysupgrade.itb to the /tmp dir of the
router using scp.
8. Run sysupgrade:
```
sysupgrade -n /tmp/squashfs-sysupgrade.itb
```
Recovery
--------
1. Place OpenWrt initramfs-recovery.itb image (with original name) on the
tftp server (IP: 192.168.1.254).
2. Press "reset" button and power on the router. After ~10 sec release the
button.
3. Use OpenWrt initramfs system for recovery.
BL2 and FIP recovery
--------------------
Use mtk_uartboot and UART connection if BL2 or FIP in UBI is destroyed:
Link: https://github.com/981213/mtk_uartboot
Return to stock:
----------------
1. Copy partition backups (BL2.bin and FIP.bin) to the /tmp dir of the
router using scp.
2. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
3. Restore stock U-Boot and reboot:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/BL2.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/FIP.bin FIP
reboot
```
4. Open U-Boot web recovery, upload stock firmware image and start
upgrade.

Deactivate CONFIG_CONTEXT_TRACKING_USER_FORCE: Force user context
tracking: This is a testing feature which should not be activate in
production environments according to the Kconfig help. It adds an extra
overhead.
Deactivate CONFIG_RCU_NOCB_CPU_DEFAULT_ALL: Offload RCU callback
processing from all CPUs by default: This option should only be used in
aggressive HPC or real-time workloads which we do not have in OpenWrt.
For normal workloads it increases the number of context switches.

It seems that we have some kind of a symbol name conflict which causes
CONFIG_SECCOMP to always be read as y.
Unfortunatelly, I could not figure out what is causing this, but simply
renaming SECCOMP to USE_SECCOMP seems to properly work and leaves the
symbol unset unless arch dependencies are satisfied.
This fixes qoriq and others that dont support seccomp from failing due
to procd-seccomp package being selected to get included but it cannot be
built for them:

This commit adds support for two variants of the already supported router
Acer Predator Connect W6: The Acer Predator Connect W6d (W6 without 6 GHz
wifi) and the Acer Connect Vero W6m (W6 without 2.5G eth1 port, usb3 port,
and the 6 on-board gpio RGB LEDs, and with a KTD2026 RGB LED controller
instead of the KTD2061 LED controller of the W6/W6d).
The device tree for the W6m refers to the KTD202x driver suggested in
PR #16860.
Patching target/linux/mediatek/filogic/base-files/lib/upgrade/platform.sh
removes the code repetition in (old) lines 121 to 124 on the occasion.

In order to prepare for OpenWrt support other Acer W6 devices and to get
a step further to full hardware support for Acer Predator Connect W6, this
commit
- adjusts the product name ("Acer Predator Connect W6")
- updates gpio LED labels to function/color scheme
- show router status by using first rgb led instead of it's red color only
(blue: booting/failsafe mode; red: sysupgrade; green: running – was: red)
- changes switch/eth1 led configuration to reflect RX/TX activity and speed
(green: full 1Gbps/2.5Gbps speed; amber: lower speed; blink: RX/TX)
- shortens dummy dm-mod.create string in bootargs
- enables W6's i2c interface

In order to prepare OpenWrt support for other Acer W6 devices and to adapt
the procedure to read and set mac addresses which other devices of the same
target are using (instead of needing an additional script and creating an
additional structure in the file system), this commit
- reads device mac addresses from u-boot environment
- avoids the detour via the file system to set the mac addresses
- drops redundant file /lib/preinit/05_extract_factory_data.sh
The idea and the implementation were thankfully taken from PR #16410.

In order to prepare OpenWrt support for other Acer W6 devices, this commit
moves all device tree components that are used by all Acer W6/W6e/W6d/W6m
routers from mt7986a-acer-predator-w6.dts to mt7986a-acer-w6-common.dtsi
(new file) and includes this dtsi file in mt7986a-acer-predator-w6.dts.
Minor changes had to be made to the device tree in order to improve clarity
and – notably – to reduce the number of dtc warnings:
- replace (obviously wrong) led@<N> gpio led entities by led-<N>
- remove unnecessary (default-state = "off") gpio led statements
- rename entity “memory” to “memory@0”
- add missing #address-cells and #address-size in /soc/mmc@11230000
- add missing #address-cells and #address-size in /soc/pcie@11280000
- introduce symbols “nvmem” and “swport0” in dtsi (referenced in dts)
The changes were checked with `diff -BEZbdtwy --suppress-common-lines ...`
(comparing two dts files created using old and new fdt-1 blobs again), see

Popular bpi-r3 pwm fans like this one
https://www.amazon.com/youyeetoo-Barebone-Fan-BPI-R3-Integrated/dp/B0CCCTY8PS
will not work properly with current openwrt-23.05/24.10 firmware.
Trying different pwm setting
echo $value > /sys/devices/platform/pwm-fan/hwmon/hwmon1/pwm1
I found:
pwm1 value fan rotation speed cpu temperature notes
-----------------------------------------------------------------
0 maximal 31.5 Celsius too noisy
40 optimal 35.2 Celsius no noise hearable
95 minimal
above 95 does not rotate 55.5 Celsius
-----------------------------------------------------------------
At the moment we have following cooling levels:
cooling-levels = <255 96 0>;
for cpu-active-high, cpu-active-medium and cpu-active-low modes correspondingly.
Thus only cpu-active-high and cpu-active-low are usable. I think this is wrong.
This patch fixes cpu-active-medium settings for bpi-r3 board.
PS: I know, the patch is not ideal as it can break pwm fan for some users.
There are some peoples that use handmade cooling solutions, but:
* discussed cooler is the only 'official' pwm cooler for bpi-r3
available on the market.
* most peoples will use passive cooling available on the market or
the discussed cooler.
* the pwm-fan dts section was added before the official cooler
appears on the market.
Thus it should not be a lot of harm from this fix.
