Why do we need to transfer roms? These are devices on the memory

Boot splash should just be another rom as it would be on a real
system.
Just like the initrd?
There isn't enough address space for a 100MB initrd in ROM.
Because of limits of the original PC, sure, where you had to fit
everything in 0xa0000-0xfffff or whatever it was.
But this isn't a real PC.
You can map the read-only memory anywhere you want.
It's not that simple. Option roms are initialized in 16-bit mode so the
physical address space is limited. The address mappings have very well
defined semantics.
