# For old QEMU we had 'simhs' qemu board, however we are going to rename it
# to 'virt' board. It will be renamed in ARC QEMU in the nearest Zephyr SDK
# (where ARCv3 HS6x support will be added to QEMU)
# Let's rely on the QEMU defaults instead of specifying exact board name,
# until the updated Zephyr SDK will be set as default. By that we keep both SDKs
# (old and new) working for ARCv2.
# After that we can specify board explicitly with '-M virt' option.
