1 Over time, support for more and more boards gets added to U-Boot -
2 while other board support code dies a silent death caused by
3 negligence in combination with ordinary bitrot. Sometimes this goes
4 by unnoticed, but often build errors will result. If nobody cares any
5 more to resolve such problems, then the code is really dead and will
6 be removed from the U-Boot source tree. The remainders rest in peace
7 in the imperishable depths of the git history. Please use the tools
8 git provides to read through this history. A common example would be:
9 $ git log -p --follow -- board/technexion/twister
10 to see the history and changes made to the Technexion "twister" board
11 from introduction to removal.
