Currently, QCA8081 LED is never configured and the default configuration
has the LED polarity inverted so it will be lit when there is nothing
connected to the PHY.
So lets define the LED as active-low and configure the trigger via 01_leds.

Do note that the default RouterBoot has disabled UART even when the
required hard-config bit is set to indicate UART support.
Patched RouterBoot must be used if UART is desired.
Also, since ARM64 Linux support does not support in any way appending the
DTB to the kernel image we use mainline U-Boot with added RB5009 support
in order to boot OpenWrt.
MikroTik uses YAFFS to store the boot kernel and we use YAFUT to put U-Boot
as the kernel which RouterBoot then simply boots as an ELF.
Install instructions:
NOTE: In case you are using an existing out of tree version of OpenWrt make
sure to reinstall RouterOS via Netinstall to return the expected partition
layout.
1. Prepare FAT or EXT4 formatted USB drive with OpenWrt initramfs:
* Copy bin/targets/mvebu/cortexa72/openwrt-mvebu-cortexa72-mikrotik_rb5009-initramfs-uImage.itb
to the root of FAT or EXT4 formatted USB drive.
* Plug in the drive to the RB5009 USB port
2. Boot the modified OpenWrt built U-Boot ELF:
u-boot.elf from bin/targets/mvebu/cortexa72/u-boot-rb5009/u-boot.elf
Consult OpenWrt wiki for common instructions on switching to boot from
Ethernet once as well as serving the file:
https://openwrt.org/toh/mikrotik/common
Once U-Boot is booted it will attempt to boot in the following order:
1. NAND
2. USB
3. Network
NAND is expected to fail but USB or Networking need to serve the OpenWrt
initramfs image and after booting it will be accessible from LAN ports
on the default 192.168.1.1 IP with default credentials.
3. Flash modified RouterBoot that enables UART (Optional but recommended):
https://public.robimarko.eu/RB5009/70x0-7.15-uart.fwf
* Copy the file over to the booted OpenWrt initramfs to /tmp
* Run: mtd erase RouterBOOT-primary
* Run: mtd write /tmp/70x0-7.15-uart.fwf RouterBOOT-primary
4. Install U-Boot to boot OpenWrt:
* Copy the u-boot.elf from bin/targets/mvebu/cortexa72/u-boot-rb5009/u-boot.elf
to OpenWrt initramfs to /tmp.
* Run: . /lib/functions.sh
* Run: yafut -d /dev/mtd$(find_mtd_index "YAFFS") -w -i /tmp/u-boot.elf -o kernel -T
This will use yafut to copy the U-Boot as kernel in YAFFS so that RouterBoot boots it.
5. Wipe the NAND UBI partition:
* Run: ubiformat /dev/mtd$(find_mtd_index "ubi") -y
This will prepare the existing RouterOS rootfs partition for OpenWrt.
6. Flash OpenWrt:
* Copy the bin/targets/mvebu/cortexa72/openwrt-mvebu-cortexa72-mikrotik_rb5009-squashfs-sysupgrade.bin
to OpenWrt initramfs to /tmp.
* Run: sysupgrade /tmp/openwrt-mvebu-cortexa72-mikrotik_rb5009-squashfs-sysupgrade.bin
Device will reboot, boot U-Boot and then OpenWrt.
Recovery:
In case you need to reinstall OpenWrt if it crashes after U-Boot, there is
a recovery mechanism in OpenWrt to boot the OpenWrt initramfs.
You need to hold the reset button while U-Boot is booting and then it will
boot the OpenWrt initramfs from:
1. USB
2. Networking
In recovery mode U-Boot will light all of the LED-s except for the switch
ones.
In case you want to return to RouterOS, you can simply do that via
Netinstall like on any other MikroTik board.

figured out the RouterBoot modification for UART, the missing 10G MVPP2
support in U-Boot as well as the custom aux loader to boot directly via
RouterBoot.

We don't have any passive trip point hence we can set the polling delay
for passive trip to 0 effectively disabling this polling.

Split thermal zone for puzzle chassis. Thermal platform supports only

Fix missing property in puzzle thermal. The thing was never supposed to
work.
Property #thermal-sensor-cells was missing from the puzzle hwmon, making
the entire thermal platform referencing that fail to probe with -EINVAL.
The puzzle hwmon expose 2 termistor but they probably use an userspace
downstream utility to configure and handle thermal. For this reason we
really don't know what they use the sensor for or when it's attached.
We use them to sensor if the Chassis gets too hot due to ambient
temperature and generic components getting too warm.

- Make step_wise thermal governor respect hysteresis
This is done by importing a downstream patch, backporting the same feature
now present in Linux v6.10+ would be too messy.
- Introduce thermal zone for the WT61P803 uC (chassis and board sensors)
- Introduce thermal zones for AQR NBase-T PHYs
- No longer modify existing SoC thermal zones (which are now only in charge
for emergency shutdown, and can be interrupt driven instead of polled)
