This is fine in most cases, but when you want to reduce the size of the particular kernel image, those big tables are, well, quite big. We haven't had the option to disable them in the past since they were hidden Kconfig options based on the SoC support. However, that granularity isn't great since we don't have one Kconfig option per-SoC, but rather one by family. Make those options selectable by the user so that they can disable it if needed, while keeping the current default to not change the standard case.
