Hi, a project I'm involved in uses a module/baseboard combo, and components on either board are described in DT. I'm currently using separate dts files which build upon each other with include statements, which works fine for development.
In production though, we will certainly have running changes (and hence different versions) over the lifetime of the product for both the baseboard and the module, and the hardware has support for identifying the versions of both sides at runtime. So let's say we have n versions of the baseboard and m versions of the module, we would much like to only prepare n + m files, instead of n * m by pre-compiling every possible combination (some of which may actually never occur 'in the wild'). So my question is: is it possible to do that kind of assembly of a number of files at runtime in U-Boot? I guess all it takes is merging a number of trees together, right? I browsed through the APIs but couldn't yet find an clear approach to that kind of problem. If not, what would it take to add that functionality? I can probably help with the implementation if someone tells me what would be the right way. Any pointer greatly appreciated.
