| 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 peace | |
| in the imperishable depths of the git history. Please use the tools | |
| git provides to read through this history. A common example would be: | |
| $ git log -p --follow -- board/technexion/twister | |
| to see the history and changes made to the Technexion "twister" board | |
| from introduction to removal. |
