util/qemu: Add `qemu` make target 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= Change-Id: I658f86e05df416ae09be6d432f9a80f7f71f9f75 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/46767 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

util/qemu: Add comprehensive default config for QEMU Q35 This config tries to mimic the actual devices of a mainboard with Intel's Q35 chipset. It provides a much better base to test coreboot (e.g. its allocator) and payloads.
