Boards:
SoC family definitions at the moment are reactive to board needs. This results in potentially wrong matches taking place for board types. Eventually, we will have descriptors match only with SoC types and should not contain anything specific to board handling and pave the way to getting rid of soc_is_XYZ checks and allow this determination done with matches at of level. Existing implicit definitions(as part of board descriptions) are explicitly documented. NOTE: Even though we prefer to have dt compatibility to explicit, "ti,dra7xx", "ti,am33xx", "ti,omap36xx" preexist in current dts and are maintained for backward compatibility. It is also expected that any future SoC addition will keep this documentation updated.
