You are right, that was my mistake. The original patch was for
drivers/video/fbdev/, and I suggested moving it out of there because
it does not depend on the fbdev subsystem, but clearly my suggestions
of drivers/video/console was equally wrong.

drivers/firmware/ is better but doesn't sound great to me either,
since one important thing the patch does is to not make it depend
on EFI firmware or BIOS style screen_info any more.
Maybe drivers/tty/earlycon_simplefb.c would work better, keeping
it close to the earlycon base support in drivers/tty/serial/,
the vt console and the old simplefb driver/, without tying to too
closely to fbdev of UEFI.
