refreshed kernel config + patches
otherwise same as 6.1/5.15.
Tested on: WNDAP620, WNDAP660, MyBook Live Single, MR24, MX60, WNDR4700

With the default BUILD_BOT configuration on a linux 6.6 kernel,
the WNDR4700's kernel no longer fits into the alloted ~3.5MiB,
even with LZMA compression.
Bigger kernels are possible, but there's a problem with Netgear's
"bootcmd":
> if loadn_dniimg 0 0x180000 0x4e0000 && chk_dniimg 0x4e0000; then nand read 0x800000 0x180000 0x20000;bootm 0x500000 - 0x800040;else fw_recovery; fi"
This loads the dni-image starting offset 0x180000 from the NAND
flash (which is the DTB partition) to 0x4e0000 in the RAM. It then
checks whenever the provided image is "valid". If it is then it
reads the DTB again to 0x800000 in the RAM and starts the extraction
and boot process. (If the image wasn't valid then it starts the
automated firmware recovery).
The issues here are that first: the kernel image gets "squeezed"
between 0x500040 and 0x7fffff... And second, the decompressor
only has area 0x0 - 0x500000 for decompression.
Hence the image now requires to update the bootcmd by providing
new values (which have been successfully tested with the original
Netgear WNDR4700 v1.0.0.56 firmware) for the RAM locations and
make full use of the fact that loadn_dniimg loads the DTB as well.
This needs to be done only once. Just connect a serial adapter to
interface with uboot and overwrite (and save) the new bootcmd.
WARNING: The serial port needs a TTL/RS-232 3.3v level converter!
Steps:
0. Power-off the WNDR4700
1. Connect the serial interface (you need to open the WNDR4700)
2. Power-up the WNDR4700
3. Monitor the boot-sequence and hit "Enter"-key when it says:
"Hit any key to stop autoboot" (Be quick, you have a ~2 second window)
4. in the Prompt enter the following commands (copy & paste)
setenv bootcmd "if loadn_dniimg 0 0x180000 0xce0000 && chk_dniimg 0xce0000; then bootm 0xd00000 - 0xce0040;else fw_recovery; fi"
saveenv
run bootcmd
Note: This new bootcmd will also unbrick devices that were bricked
by the bigger 4.19-6.1 kernels.
Note2: This method was tested with a WNDR4700. A big kernel with most
debug features enabled on v6.6.22 measured 4.30 MiB when compressed
with lzma. The uncompressed kernel is 12.34 MiB. This is over the 3 MiB,
the device reserves for the kernel... But it booted! For bigger kernels,
the device needs repartitioning of the the ubi partition due to the
kernel+dtb not fitting into the partition.
Note3: For initramfs development. I would advice to load the initramfs
images to 0x800000 (or higher). i.e.: tftp 800000 wndr4700.bin
Note4: the fw_recovery uboot command to transfer the factory image to
the flash still works.

This service was unfunctional due to not having its executable bit set.
Furthermore, sysupgrade complains about the file being present in images.
Also, the tc654 driver doesn't provide pwm1_enable sysfs file, instead its
now called pwm1_mode.
Please note that the fan was always spinning. It should now turn off, when
there's enough the thermal headroom.

it is possible to boot and run OpenWrt from an image on an USB-Stick
on the MyBook Live DUO. (No, the MyBook Live Single does NOT have an
USB-Port and attempts at enabling it sadly all failed... so far).
To do that:
First, prepare a USB-Stick by writing the raw and uncompressed OpenWRT
factory image for the device onto the stick (i.e.
# gunzip -c openwrt-*wd_mybooklive*-factory.img.gz > /dev/sd$XX).
Then enter the u-boot via an attached TTL/CMOS 3.3V cable adapter and
give the following commands a try in the:
usb start; sata init
ext2load usb 0:1 ${fdt_addr_r} /boot/apollo3g.dtb
ext2load usb 0:1 ${kernel_addr_r} /boot/uImage
setenv bootargs 'root=/dev/sdc2 rw rootfstype=squashfs,ext4 rootdelay=5'
run addtty; bootm ${kernel_addr_r} - ${fdt_addr_r}
Notes:
- booting from USB-Sticks takes a long time! Be prepared to wait a few
minutes. (~3 minutes for 4 MiB /boot/uImage file on a USB 2.0 Stick)
- the bootargs part 'root=/dev/sdX2' depends on how many HDDs/SSDs are
slotted in. (if none: then use sda, if one: sdb. if two: sdc)
- rootdelay is important as the storage on the USB-Sticks do not show
up fast enough. 5 seconds might be excessive though.
- it's possible to concat these commands together in one line and
write it into u-boot's "bootcmd" environment variable and save the
environment to make the device to always boot from USB from then on.
if you have accidentally overridden the 'bootcmd' and want to return
to 'spec' enter the following commands :
setenv bootcmd 'run boot_sata_script_ap2nc'
saveenv

Note about the MyBook Live.
The MyBook Live didn't have the encompassing fixed-partitions.
This is needed for the u-boot,env compatible to be read as otherwise
the kernel assumes this is a legacy NOR/NAND node and this binding
is unsupported.

prepend-dtb got extended to handle the Meraki devices too,
the problem here was that the Netgear WNDR4700 expects an
u-boot header in front of the DTB, whereas Meraki devices
don't.
Since the header was dropped, the WNDR4700's uboot started
to complain:
Bad Magic Number,it is forbidden to be written to flash!!
when flashing the factory.img since it expects an u-boot
header there.

In order to cut down on the Netgear WNDR4700, the ata

devices too to save up on kernel size (~200 kb).

Thanks to Ewald who figured out that the "jedec-probe" vs.
"jedec-flash" was the wrong binding. With this information
and the jedec-probe support enabled => the chip works.

This patch copies over refreshed config and patches from 5.10
with the following changes:
- dropped superfluous tc654/tc655 variant detection patch
(tc654 support will become available upstream starting with
5.17-rc7+).
- dropped xhci msi(x) workaround... as the broken MSI(X)
is now gone.
- dropped dwc2 workaround since the driver was fixed and it
works without it.
Please note: Netgear WNDAP660 & WNDAP620 users:
Due to the kernel's size increase, uboot will likely break
because it is overwrite the kernel during decompression.
To fix this (and debrick affected devices, no reflash
necessary), attach the RJ45-Serial-Console cable and
enter the following in the uboot prompt during bootup:
setenv kernel_addr_r 1100000
saveenv
run bootcmd
to restore the old/previous behavior:
setenv kernel_addr_r 600000
saveenv
run bootcmd

Upstream hwmon-maintainer had various comments about
the changes to the tc654 driver. These have been
addressed and the cooling device support is destined
for inclusion.
One of the comments was the change of the cooling states
scaling. No longer the driver uses the same values as the
hwmon interface, instead the states are now the 17 states
the tc654 supports.
