This changes the virt target so that it can be run with the -bios option and a pflash backend for the flash. QEMU can now be run as follows: qemu -M virt -m 1G -nographic -bios build/coreboot.rom \ -drive if=pflash,file=./build/coreboot.rom,format=raw coreboot will start in DRAM, but still have a flash to put CBFS onto and to load subsequent stages and payload from.
