Hi Julian, welcome to coreboot development :)

PS2: 
i'm a bit surprised that the devicetree is identical, but i'd guess that the devices are just very similar. cw-adl-4l-v2.0, which i have started to port, but didn't have to time to finish that one yet, has some devicetree differences compared to cw-adl-4l-v1.0

i think this is missing the following lines here to make the board selection work properly:

```
config BOARD_CWWK_CW_ADL_4L_V1
    select BOARD_CWWK_ADL_N_COMMON

config BOARD_CWWK_CW_ADLNTB_1C2L_V3
    select BOARD_CWWK_ADL_N_COMMON
```
