If the platform devices are statically defined, they get no release

The alternative to statically defined devices is
platform_device_alloc(), which does provide a release method, but I
can't call it at arch_initcall time because the console_initcall has
already happened. And I can't use it at setup_arch() time (when the
boot info is parsed) because there's no kmalloc() yet.
What to do? I don't want to export the bootinfo data to the pmac_zilog
driver for console initialisation. And I'd really like to avoid a
bunch of hard coded SCC base addresses.
Any suggestions?
Could you just define and set a release function that does nothing?
That's kind of silly, but it seems like it should work. If it's static
memory anyway, there isn't anything to free.
I guess it is a cheap enough. It does work.
Thanks,
