   3 # This automatically adds a `qemu` make target if a compatible
   4 # configuration is selected. There are some notable variables
   5 # that can be set or adapted in `Makefile.mk` files, the make
   6 # command line or the environment:
   7 #
   8 # Primarily for `Makefile.mk` use:
   9 # QEMU-y                the QEMU executable
  10 # QEMU_CFG-y            a QEMU config that sets the available default devices,
  11 #                       used to run more comprehensive tests by default,
  12 #                       e.g. many more PCI devices
  13 #
  14 # For general use:
  15 # QEMU_ARGS             additional command line arguments (default: -serial stdio)
  16 # QEMU_EXTRA_CFGS       additional config files that can add devices
  17 #
  18 # QEMU_CFG_ARGS         gathers config file related arguments,
  19 #                       can be used to override a default config (QEMU_CFG-y)
  20 #
  21 # Examples:
  22 #
  23 #   $ # Run coreboot's default config with additional command line args
  24 #   $ make qemu QEMU_ARGS="-cdrom site-local/grml64-small_2018.12.iso"
  25 #
  26 #   $ # Force QEMU's built-in config
  27 #   $ make qemu QEMU_CFG_ARGS=
