You can deduce such things by looking into Makefile-s and KConfig-s:
- dnfb is used by apollo platform of m68k arch
- igafb can be used on sparc32 arch

I took care of compile testing these changes and discovered that
in the current vanilla kernel (v4.14-rc4) igafb fails to build.

Thus I've only queued dnfb changes for v4.15 kernel for now.
