Also developers incorrectly think these are already booleans: $ git grep -E '\b(no_parallel|no_serial|no_floppy|no_cdrom|no_sdcard|pci_allow_0_address|legacy_fw_cfg_order)\b' | grep -E '(true|false)' hw/arm/sbsa-ref.c: mc->pci_allow_0_address = true; hw/arm/virt.c: mc->pci_allow_0_address = true; hw/arm/xlnx-versal-virt.c: mc->no_cdrom = true; hw/m68k/next-cube.c: mc->no_cdrom = true; hw/ppc/spapr.c: mc->pci_allow_0_address = true; hw/riscv/virt.c: mc->pci_allow_0_address = true; > > Convert the MachineClass bitfields used as boolean as real ones. > > Suggested-by: Daniel P.
