So, please stop. > >From hardware side, I think we are on same page. Hamoa and Purwa modules are not same SoM, but they are very similar. The only difference is different SoC, PCI, APC supply and one PMIC. The circuit boards are same. We have exactly same case on Hamoa/Purwa CRD which uses a common dtsi. Can we use common dtsi for the hardware boards which are very similar? Is that very strict that the hardware boards have to be exactly same?
