[U-Boot] [PATCH v6 07/15] Do not apply: tools: add gen_maintainers.py

[Masahiro Yamada]

 ========================================
 Do not apply this patch to the main line
 ========================================

This tool generates MAINTAINERS files based on boards.cfg file.

Because it is used only once, it should not be applied.
