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.
I wasn't talking about the 1MB limit, rather the 4GB limit. Of that,
3-3.5GB are reserved for RAM, 0.5-1GB for PCI. Putting large amounts of
ROM in that space will cost us PCI space.
100 MB initrds are a bad idea for multiple reasons. Demand paging is
there for a reason.
