I just installed the latest almalinux on my raspberry pi cm4 using:
89773106f23407efb5258d7185d2005c6ed4f98f2ad23916948be573eb2efb95 AlmaLinux-8-RaspberryPi-latest.aarch64.raw.xz

Everything was seamless except for wifi.

There was no wifi driver file for a pi CM4 in /lib/firmware/brcm

I found a post by @geerlingguy in openwrt forums with the solution.

# cp /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-compute-module.txt

running the above command and rebooting resolved my issue.

It would seem that openwrt has implemented something similar into their upstream

This should be resolved now. https://git.almalinux.org/rpms/linux-firmware-raspberrypi/commit/f686057b99ace67e9fe82ff8fd1aa182abdc7ebb

Feel free to come back if it doesn't work on CM4.
