wifi work before last bootloader update.
does disable-bt matter wifi dead.
btw, test kernel-rc then audio dead.
All of the above works here. I am leaning towards some issue on your end with:
pi wifi router relationship and or config and the same with your sound with a config.
I got home and booted my unstable image, and it was minus the wifi device. I rolled back the linux-firmware and wifi was restored. Then reinstaleld the new linux-firmware, rebooted and wifi device was gone again. Rolled back again and the wifi device was back. So currently I am running on the previous version as I need wifi.
Not sure why I just now noticed this. Maybe I forgot to reboot after the update last night? Sorry I did not find this sooner.
Interesting that my wifi works on the stable branch. To be clear it was the linux-firmware package and not firmware-raspberrypi.
pacman -U linux-firmware-20201218.646f159-1-any.pkg.tar.xz
That is my exact roll-back command. There is no reference to wlan0 in dmesg or journalctl -b with the new linux-firmware installed.
I just found that dracut is indeed passing a kernel command line, and it is my old one. So I am investigating that. But I don’t think the cmdline.txt changes has any effect on the wifi.
$ cat /boot/cmdline.txt
root=LABEL=MNJRO_ROOT rw rootfstype=btrfs rootwait console=serial0,115200 console=tty1 selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=serial0,115200 usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0 usb-storage.quirks=152d:1561:u
$ cat /proc/cmdline

So I made the change to cmdline.txt, but dracut is biting me now. 
I will boot my arm-testing and grab the new firmware and try that.
Edit: this will take a several minutes due to download time. But I wanted to say no Dracut on my arm-testing, so this will be a better test.
The new firmware-raspberrypi is supposed to fix a dis-connect issue with the pi4 wifi but the problem is it’s new files are in usr/lib/firmware/updates/brcm compounded by linux-firmware packages puts it’s files in /usr/lib/firmware/brcm which also has firmware for the pi4 wifi which would normally not be an issue because linux is supposed to look first in /usr/lib/firmware/updates first.
The kicker is it is hard coded to the /usr/lib/firmware/brcm directory for it to look for the firmware to load so it will never see the latest firmware and lately the linux-firmware package is providing outdated and in this case now looking like bad firmware for the pi wifi.
I can not dump the firmware-raspberrypi package in /usr/lib/firmware/brcm as it will refuse saying the files exist belonging to linux-firmware.
My freshly updated arm-testing has the same issue with the linux-firmware. So I am back to the previous version.
The thing that has me stumped now is:
$ cat /proc/cmdline
coherent_pool=1M 8250.nr_uarts=1 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1 video=HDMI-A-1:1920x1080M@60 smsc95xx.macaddr=DC:A6:32:C1:E1:C7 vc_mem.mem_base=0x3eb00000 vc_mem.mem_size=0x3ff00000 root=LABEL=MNJRO_ROOT rw rootfstype=btrfs rootwait console=ttyAMA0,115200 console=tty1 selinux=0 kgdboc=ttyAMA0,115200 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0 usb-storage.quirks=152d:1561:u

I now suspect the systemd hook for mkinitcpio, that is common between my stable and testing installs.
Edit: I replaced the systemd hook with udev… and now I am stumped.
$ cat /proc/cmdline
coherent_pool=1M 8250.nr_uarts=1 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1 video=HDMI-A-1:1920x1080M@60 smsc95xx.macaddr=DC:A6:32:C1:E1:C7 vc_mem.mem_base=0x3eb00000 vc_mem.mem_size=0x3ff00000 root=LABEL=MNJRO_ROOT rw rootfstype=btrfs rootwait console=ttyAMA0,115200 console=tty1 selinux=0 kgdboc=ttyAMA0,115200 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0 usb-storage.quirks=152d:1561:u
I do not know what you are referring to specifically. If you are saying more stuff is added than what is in cmdline.txt there are system defaults it knows to add to your cmdline.txt to get it booting properly. So there will be more in addition to your cmdline.txt in /proc/cmdline as that is what it is using in it’s entirety to boot with.
Oh, sorry I was not clear.
Something is changing my command line from:
console=serial0,115200
to:
console=ttyAMA0,115200
No dracut on this install, so can’t be related to that. I then suspected the systemd hook but I switched to udev and /proc/cmdline shows exactly what we just changed in cmdline.txt
I see now. That should not worry you at all. That terminal is reserved for bluetooth and it is a messed up deal I believe to begin with. In post #343 above I talked about it where we had ttyAMA0 and had to change it to serial0 so bluetooth to work. In my trials to get it to work I found that you have to no say serial0 in cmdline.txt but for some reason in the end it will use the ttyAMA0 terminal as that is what is used to patch the firmware to the ram that attach-bluetooth does. In the end /dev/serial0 does not exist.
Messed up deal but you have bluetooth disabled and if you did not it is going to do what it does anyway.
Find something else to worry about… lol

lol, yes, that would explain it.
And the next time I go off on another meaningless tangent, even if you don’t know the answer, just make one up and help put me out of my misery. 
As for the firmware issue:
$ mount --bind /usr/lib/firmware/updates/brcm /usr/lib/firmware/brcm
Probably not a solution you prefer, but it might work with a fstab entry and a couple alpm hooks to (un)mount on linux-firmware updates. Or maybe trigger a reinstall of firmware-raspberrypi.
Edit2 : Well, I decided to give it a try and see if it actually works. Evidently the bind mount does not occur soon enough. Once booted, the mount is in place and works as expected, but still no wlan0. I wonder if there is a way to trigger that mount sooner, or delay the loading of the firmware until after the mount?
Well, it would seem that I have managed to get the latest linux-firmware to work, I have wlan0 now. How did I do it? What changed? I am not sure, as I was not expecting this result from my actions.
I think it begins with the bind mount above. I mistakenly started a linux-firmware re-install of the previous version, with the bind mount in place. I hit ctrl-c durring the update and it appeared to finish writing the firmware files and then the update terminated.
I then umount the bind mount and reinstalled the linux-firmware package, then I reinstalled the firmware-raspberrypi. There were no complaints from pacman at this point, as I recall.
I rebooted and had wifi as expected.
This is were I am not exactly sure… but I believe I then attempted to re-upgrade the linux-firmware as I wanted to investigate more why the bind mount did not work. But pacman complained that the following files already existed on the filesystem:
/usr/lib/firmware/brcm/brcmfmac43012-sdio.bin
/usr/lib/firmware/brcm/brcmfmac43012-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac43430-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac43455-sdio.Raspberry Pi Foundation-Raspberry Pi 4 Model B.txt
/usr/lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac4354-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac4356-pcie.clm_blob
/usr/lib/firmware/brcm/brcmfmac4356-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac4356-sdio.vamrs,rock960.txt
/usr/lib/firmware/brcm/brcmfmac43570-pcie.clm_blob
/usr/lib/firmware/brcm/brcmfmac4373-sdio.clm_blob
/usr/lib/firmware/brcm/brcmfmac54591-pcie.bin
/usr/lib/firmware/brcm/brcmfmac54591-pcie.clm_blob
So I then deleted each of the above and then successfully reinstalled both the new linux-firmware and firmware-raspberrypi and rebuilt initramfs and then rebooted.
And to my surprise, I now have working wifi with the new firmwares.
It appears you strive to keep my head spinning with your endeavors. 
My only question is that is there nothing wrong with the latest linux-firmware or firmware-raspberrypi packages now?
Well, as wifi seems to be working with the newest packages, they must be fine. Maybe I had a old symbolic link that was “misdirecting” the kernel as to which firmware to use? I really do not know at this point.

Quite different.
The brcmfmac43455’s are the files that affect you.
Below are the current links that pacman complained about already existing on the file system, and that I manually deleted. I suspect something here as this was the only “non-standard” event I experienced. It caused me to do something I do not normally do. Since the normal updates did not result in a working wifi, the things done out of the ordinary would likely contain the “fix”.
