Ah, good point, I should have remembered that Gerd offers a CSM build in
his repo!

So, you can easily look up the build instructions, in Gerd's SeaBIOS and
OVMF RPM "spec" files. Check out these git repositories:

  https://git.kraxel.org/cgit/jenkins/seabios/
  https://git.kraxel.org/cgit/jenkins/edk2/

Specifically:

  https://git.kraxel.org/cgit/jenkins/seabios/tree/seabios.git.spec
  https://git.kraxel.org/cgit/jenkins/edk2/tree/edk2.git.spec.template

HTH,
Laszlo
