+Over time, support for more and more boards gets added to U-Boot -
+while other board support code dies a silent death caused by
+negligence in combination with ordinary bitrot.  Sometimes this goes
+by unnoticed, but often build errors will result.  If nobody cares any
+more to resolve such problems, then the code is really dead and will
+be removed from the U-Boot source tree.  The remainders rest in piece
+in the imperishable depths of the git history.  This document tries to
+maintain a list of such former fellows, so archeologists can check
+easily if here is something they might want to dig for...
