It also means there is no way to get the console up without the right
firmware files in the filesystem. I think that is really crap compared
to what we have today where the display will always come up, and
basically a regression.

I understand the stance with respect to things like add-on hardware
like a Bluetooth board or WLAN or whatnot. But the fbdev console
is just too basic, like a serial port IMO.

Sure in the ARM world we usually have a serial console, but this is
seriously breaking current practice.

As Tomi mentioned firmware files can be located in the kernel image; there is no
requirement to be in a filesystem, and that application can be performed really
early, before even early init.

Are you thinking about exploiting an appended DT with
CONFIG_ARM_APPENDED_DTB or something else?
