What I should have asked is: do you expect architectures other than X86
to set HAVE_EARLY_PCI? Because then you should put that Kconfig entry in
a file reachable by all architectures. Say, in init/Kconfig or in
drivers/tty/serial/Kconfig.

(You can also have an entry for HAVE_EARLY_PCI for each arch that needs
it, but that would be a bit silly.)

Thanks,
