2022-08-12dm: core: Introduce support for multiple treesSimon Glass
At present ofnode only works with a single device tree, for the most part. This is the control FDT used by U-Boot. When booting an OS we may obtain a different device tree and want to modify it. Add some initial support for this into the ofnode API. Note that we don't permit aliases in this other device tree, since the of_access implementation maintains a list of aliases collected at start-up. Also, we don't need aliases to do fixups in the other FDT. So make sure that flat tree and live tree processing are consistent in this area. Signed-off-by: Simon Glass <[email protected]>
2022-08-12dm: core: Split out the declaration of ofnodeSimon Glass
This is used by a lot of files, but ofnode.h needs to include a lot of header files. This can create dependency cycles, particularly with global_data.h which must include various declarations. Split the core delcarations into a separate file to fix this. Signed-off-by: Simon Glass <[email protected]>
