config BOARD_DEPRECATED_RELEASE
string
help
This hidden option is set in the board configuration and indicates
the Zephyr release that the board configuration will be removed.
When set, any build for that board will generate a clearly visible
deprecation warning.
config QEMU_TARGET
bool
help
Mark all QEMU targets with this variable for checking whether we are
running in an emulated environment.
config NET_DRIVERS
bool
default y if QEMU_TARGET && NETWORKING
help
When building for a qemu target then NET_DRIVERS will be default
enabled to allow for easy use of SLIP or PPP

help
Enable QEMU virtual instruction counter. The virtual cpu will
execute one instruction every 2^N ns of virtual time. This will
give deterministic execution times from the guest point of view.
config QEMU_ICOUNT_SHIFT
int "QEMU icount shift value"
depends on QEMU_ICOUNT
help
The virtual CPU will execute one instruction every 2^N nanoseconds
of virtual time, where N is the value provided here.
config QEMU_IVSHMEM_PLAIN_MEM_SIZE
int "QEMU ivshmem-plain shared memory size in mega-bytes"
default 1
depends on QEMU_TARGET && IVSHMEM && !IVSHMEM_DOORBELL
help
This sets the size of the shared memory when using ivshmem-plain
device in Qemu. Note that it's in mega-bytes, so 1 means 1M for Qemu
etc..
config QEMU_UEFI_BOOT
bool "QEMU uses UEFI to boot up"
default n
depends on BUILD_OUTPUT_EFI && QEMU_TARGET && X86_64
help
This option indicates that QEMU will use UEFI bootable method
to boot up.

config BOARD_HAS_TIMING_FUNCTIONS

Should be selected if board provides custom method for retrieving
timestamps and cycle count.
