If I understood you correctly, you mean the following config is
invalid don't you?

ixpcom* at ixpsip? addr 0xf0000000 size 0x4000
                        ^^^^^^^^^^virtual address

It is hard of avoiding for console to access UART through the
statically mapped address (virtual 0xf0000000).  Because I want
to use console before the vm is established.

So I will modify sources as following.

        - to identify device instance, using hardware address.
        - when console accesses device, using statically mapped address.
        - when tty accesses device, using handler given by bus_space_map().
