Recently I noticed (for reference in the NCS/v3.1.1 SDK) that some nrf9151 boards are in zephyr folder structure and others are in the nrf folder structure.
NRF9151DK is found C:\<my_ncs>\v3.1.1\zephyr\boards\nordic\nrf9151dk
thingy91x is found in C:\<my_ncs>\v3.1.1\nrf\boards\nordic\thingy91x
Is the NRF location the go forward folder structure for Nordic dev kits?
Thanks,
Greg
