	  This option prevents Option ROMs from doing dirty tricks with the

config YABEL_PCI_ACCESS_OTHER_DEVICES

	help
	  Per default, YABEL only allows Option ROMs to access the PCI device

	  By default, YABEL aborts when the Option ROM tries to write to other
	  devices' config spaces. With this option enabled, the write doesn't
	  follow through, but the Option ROM is allowed to go on.
	  This can create issues such as hanging Option ROMs (if it depends on

	bool
	depends on PCI_OPTION_ROM_RUN_YABEL && ARCH_X86
	help
	  YABEL consists of two parts: It uses x86emu for the CPU emulation and
	  additionally provides a PC system emulation that filters bad device
	  and memory access (such as PCI config space access to other devices
	  than the initialized one).

	  When choosing this option, x86emu will pass through all hardware
	  accesses to memory and I/O devices to the underlying memory and I/O
	  addresses. While this option prevents Option ROMs from doing dirty
	  tricks with the CPU (such as installing SMM modules or hypervisors),
	  they can still access all devices in the system.
	  Enable this option for a good compromise between security and speed.
