Our original intention of providing kernel built-in DTS is to describe all possible device information of that SoC, so that everyone can use it as a reference during development; we will unlikely to add more .dts files to the kernel besides the reference ones. And as a reference, our built-in DTS provides the most basic bootable combinations (so it is generic enough) as an alternative in case the DTS in the bootloader is unexpected. Does this make any sense? Thanks. Binbin > Rob
