Getting Rid of Aspeed Firmware Warning

Every time I would run update-initramfs, I would receive the following warning on my SuperMicro machine:

Console  Copy
update-initramfs -u
update-initramfs: Generating /boot/initrd.img-5.4.0-42-generic
W: Possible missing firmware /lib/firmware/ast_dp501_fw.bin for module ast

This issue is well-known and harmless. It's just a hardcoded value that's checked by ASPEED driver and, if file is not present, results in this warning.

If you are tired of it and you just want to make driver happy, create an empty file at that spot:

Console  Copy
touch /lib/firmware/ast_dp501_fw.bin

And now the warning is gone. :)
