This allow developers to create board files without the SoC name when
the board only defines a single SoC.
This means that a board, such as rpi_pico, which defines only a single
SoC, rp2040, and one variant, now allows the following file names:
Board target: rpi_pico/rp2040
- dts: rpi_pico_rp2040.dts, short: rpi_pico.dts
- defconfig: rpi_pico_rp2040_defconfig, short: rpi_pico_defconfig
- overlay: rpi_pico_rp2040.overlay, short: rpi_pico.overlay
- conf: rpi_pico_rp2040.conf, short: rpi_pico.conf
Board target: rpi_pico/rp2040/w
- dts: rpi_pico_rp2040_w.dts, short: rpi_pico_w.dts
- defconfig: rpi_pico_rp2040_w_defconfig, short: rpi_pico_w_defconfig
- overlay: rpi_pico_rp2040_w.overlay, short: rpi_pico_w.overlay
- conf: rpi_pico_rp2040_w.conf, short: rpi_pico_w.conf
A multi CPU cluster board, nrf5340dk:
Board target: nrf5340dk/nrf5340/cpunet
- dts: nrf5340dk_nrf5340_cpunet.dts, short: nrf5340dk_cpunet.dts
- defconfig: nrf5340dk_nrf5340_cpunet_defconfig,
short: nrf5340dk_cpunet_defconfig
- overlay: nrf5340dk_nrf5340_cpunet.overlay,
short: nrf5340dk_cpunet.overlay
- conf: nrf5340dk_nrf5340_cpunet.conf, short: nrf5340dk_cpunet.conf
A multi SoC board, nrf5340dk (real: nrf52840, emulated: nrf52811):
Board target: nrf52840dk/nrf52840
- dts: nrf52840dk_nrf52840.dts, short: Not possible
- defconfig: nrf52840dk_nrf52840_defconfig, short: Not possible
- overlay: nrf52840dk_nrf52840.overlay, short: Not possible
- conf: nrf52840dk_nrf52840.conf, short: Not possible
If two conflicting files are found, for example both
rpi_pico_rp2040.overlay and rpi_pico.overlay, then an error is raised.
If short form is detected for a board target with multiple SoCs, for
example nrf52840dk_nrf52840.overlay and nrf52840dk.overlay, then an
error is raised.
