Mapping Physical Memory without a Device?

I would like to be able to map memory before I have a device to work with (to read system BIOS information or mess with the video buffer). Is this possible? In linux, I would just call ioremap_nocache or request region. Is there a way to use bus_alloc_resource or something similar to accomplish this?
