Today the BuR common stuff is only used on AM33XX boards. In future we plan to have many other platforms than AM33XX so we have to move arch- specific #include(s) to responsible #ifdef sections. By the way we drop unneeded #include(s). Signed-off-by: Hannes Schmelzer <hannes.schmelzer@br-automation.com>
