[PATCH v2 00/12] bootm: Support substitions in bootargs and add tests

[Simon Glass]

This series adds tests to the fixup_silent_linux() function and extends
the 'zimage' command to use it.

It also adds a new string-substition feature to allow bootargs to be a
template, rather than having to build it up piece by piece with
information obtained in a build script.

It also updates zimage to use the same command-line processing.

With these additions it is possible to boot Chrome OS from a U-Boot script
on most Chromebooks.

Changes in v2:
- Add a new patch to support macro processing with a fixed-size buffer
- Use ${} for subtitution instead of %
- Tweak cover letter
