You can check and see if the ROM is really big and use vmalloc, if

not

then you use kmalloc (if I remember correctly my radeon has a 4KB

ROM -

vmalloc would be overkill).

You can also read it out to userspace in a loop in chunks thus
needing
only a single 4K page or you could mmap it

We have to copy the whole thing when the driver tells us to. After we
copy the ROM the hardware is going to use the address decoder for
something else. There is no safe way to get back to the ROM again other
than to unload the device driver.
