I think there is a need for Kconfig to specify that a functionality could
be built as a module or not built at all.
Some drivers require that firmware is loaded when the driver is
initialized. The kernel has functionalities for this by using a userspace
program. However, this userspace program is only usable from modules and
not during boot while any initrd or any other file system has not yet been
mounted and yet less any processes started.
That's wrong. You can load firmware from the initramfs even if the
driver is built in. There is no valid reason why a driver shouldn't
be allowed to be built in.
Could you please explain how this is supposed to work?
As far as I understand, the kernel initializes all built-in drivers, and
only then starts /init in initramfs (which is then supposed to start
udevd and load firmware) - but that's too late.
