Are you remembering to add in the firmware to the kernel image too?
i copied all from official linux-firmware.gif to /lib/firmware
That's not sufficient, you need to tell the kernel explicitly which firmware will be needed.
In other words try mentioning everything in /lib/firmware/amdgpu as CONFIG_EXTRA_FIRMWARE.

There's a good guide at https://wiki.gentoo.org/wiki/AMDGPU#Known_firmware_blobs
I've successfully used AMDGPU builtin on Tonga, Raven, Renoir and Navy
Flounder systems
I've never used kexec so have no suggestions for that
it may be back then when i compiled it inline not as module i didnt include firmware in the initrd so that may been that
about kexec, i dunno, X dri doesnt work after first kexec, after second screen at all is blank
driver init problems ..
cheers..
