This was discussed in the earlier v2 [1] — even though the PCB is not common, the majority of the hardware blocks and their wiring are functionally identical between monaco-evk and monaco-ac-evk, with only difference in H/W being 4 PMIC in monaco-evk v/s 2 PMIC on monaco-ac-evk and the rail which is supplied to the SDHC controller. The intent here is to avoid duplication across the two boards rather than imply a shared PCB, similar to what was discussed earlier. If this approach is still not acceptable without a common PCB, can I drop the refactoring and keep the DTS files fully separate ?
