[PULL 19/28] hw/i386/isapc.c: replace rom_memory with system_memory

Posted by Paolo Bonzini 1 month ago

From: Mark Cave-Ayland <mark.caveayland@nutanix.com>

Now that we can guarantee the isapc machine will never have a PCI bus, any
instances of rom_memory can be replaced by system_memory and rom_memory
removed completely.
