How can I check if amdgpu is loaded during intiramfs operation?
Anyway, I think that lsinitramfs shows that firmware is included:

$ lsinitramfs /boot/initrd.img-$(uname -r) | grep amdgpu
usr/lib/firmware/4.19.0-5-amd64/amdgpu
usr/lib/firmware/4.19.0-5-amd64/amdgpu/banks_k_2_smc.bin
usr/lib/firmware/4.19.0-5-amd64/amdgpu/bonaire_ce.bin
usr/lib/firmware/4.19.0-5-amd64/amdgpu/bonaire_k_smc.bin
...


Seems that its location is usr/lib/firmware, while it is installed in
/lib/firmware on the root filesystem...
