Firmware is always separate from kernel unless you build the firmware into the
kernel image. Usually, you would only do this for kernel options that you
decide to have built-in (i.e. CONFIG_DRM_I915=y) instead of as modules (=m)
however distributions don't do this and instead build as modules.

I agree, Alec, that is lots s better that anything I've seen older amd's
do. Which explains why my stuff

To clarify, you still need to use M instead of SUBDIRS, but the "FATAL: parse

All the LinuxCNC kernel modules build now against 5.4 albeit with several VLA

I can't use 2.8 because master has all of the things I need. I'll try a few
