[U-Boot] [PATCH v2 0/3] kbuild: always use relative path for __FILE__

[Masahiro Yamada]

We discussed the __FILE__ problem when U-Boot is built out of tree.
https://www.mail-archive.com/u-boot@lists.denx.de/msg242852.html

The deeper your build directory is located, the larger
your U-Boot image becomes.
If your platform has memory footprint limit, this is a problem.

Recently, I submitted the following patches to Kbuild ML.
(no RFC, this time)
https://patchwork.kernel.org/patch/10001419/
https://patchwork.kernel.org/patch/10001409/

I consider them for Linux 4.15 unless there is
a strong objection or a problem report.

This series is a port for U-Boot.

If Tom wants to pick this up earlier, it is OK.
If not in hurry, you can wait for the activity in Linux.
Either will do.


Changes in v2:
  - Rephrase comments for clarification
  - Fix a typo

  kbuild: add stringify helper to quote a string passed to C files
  kbuild: redefine __FILE__ as relative path from $(srctree) if possible
