This however is sometimes not enough as all of the IPQ8074 boards that I have access to dont have the qmi-board-id properly fused and simply return the default value of 0xFF. So, to provide the correct qmi-board-id add a new DT property that allows the qmi-board-id to be overridden from DTS in cases where its not set. This is what vendors have been doing in the stock firmwares that were shipped on boards I have.
