Add some mechanics to automatically have a `qemu` make target for
supported configurations. So with a QEMU target selected in Kconfig,
one would ideally only have to run `make qemu` to test things.
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=
