Add .gitattributes for line endings When building U-Boot host tools for Windows from Microsoft Azure Pipelines, we see tons of weird warnings and errors emitted from every Kconfig files: Kconfig:6:warning: ignoring unsupported character '' Kconfig:6:warning: ignoring unsupported character '' Kconfig:8:warning: ignoring unsupported character '' Kconfig:9:warning: ignoring unsupported character '' Kconfig:10:warning: ignoring unsupported character '' Kconfig:10:warning: ignoring unsupported character '' Kconfig:13:warning: ignoring unsupported character '' arch/Kconfig:1:warning: ignoring unsupported character '' arch/Kconfig:2:warning: ignoring unsupported character '' arch/Kconfig:2:warning: ignoring unsupported character '' arch/Kconfig:4:warning: ignoring unsupported character '' ... After several rounds of experiments, it turns out this is caused by line endings. Historically, Linux and macOS used linefeed (LF) characters while Windows used a carriage return plus a linefeed (CRLF). When Azure Pipelines checks out the U-Boot repo, Git tries to compensate for the difference by automatically making lines end in CRLF in the working directory on Windows, which confuses the Kconfig file parsing logic. Fortunately Git provides a way for repos to tell Git not to do such automatical line endings conversion via .gitattributes file below: * text eol=lf Signed-off-by: Bin Meng <bmeng.cn@gmail.com> 2019-10-27 12:19:46 +00:00			`# Declare files that always have LF line endings on checkout`

gitattributes: dont treat non-text files as text With recent update in u-boot gitattributes all files are treated as regular text files. This creates problems with special files and repo always shows uncommitted files like below. Your branch is up-to-date with 'origin/master'. Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) modified: tools/logos/compulab.bmp modified: tools/logos/denx-comp.bmp modified: tools/logos/toradex.bmp To fix above problem special files bmp/ttf files are treated as binary files in the gitattributes.
