# This automatically adds a `qemu` make target if a compatible
# configuration is selected. There are some notable variables
# that can be set or adapted in `Makefile.inc` files, the make
# command line or the environment:
#
# Primarily for `Makefile.inc` use:
# QEMU-y the QEMU executable
# QEMU_CFG-y a QEMU config that sets the available default devices,
# used to run more comprehensive tests by default,
# e.g. many more PCI devices
#
# For general use:
# QEMU_ARGS additional command line arguments (default: -serial stdio)
# QEMU_EXTRA_CFGS additional config files that can add devices
#
# QEMU_CFG_ARGS gathers config file related arguments,
# can be used to override a default config (QEMU_CFG-y)
#
# Examples:
#
# $ # Run coreboot's default config with additional command line args
# $ make qemu QEMU_ARGS="-cdrom site-local/grml64-small_2018.12.iso"
#
# $ # Force QEMU's built-in config
# $ make qemu QEMU_CFG_ARGS=
