[U-Boot] [PATCH v3] patman: add distutils based installer

[Chris Packham]

To make it easier to use patman on other projects add a distutils style
installer. Now patman can be installed with

  cd u-boot/tools/patman && python setup.py install

There are also the usual distutils options for creating source/binary
distributions of patman.

This gives us something that can be distributed separately as well as
in-tree. The import trick allows the python module "patman" to be
distributed and enables in-tree use without moving things around. An
alternative would be to move the files into a sub directory
(unfortunately a directory called "patman" would clash with the existing
symlink).

Thanks,
Chris

Changes in v3:
- Add installation instructions to tools/patman/README
- Drop RFC, Add sign-off
- Collect tested tag from Simon

Changes in v2:
- Install as "patman" package
- Allow running in-tree or out-of-tree

+How to install it
+=================
+
+The most up to date version of patman can be found in the U-boot sources.
+However to use it on other projects it may be more convenient to install it as
+a standalone application. A distutils installer is included, this can be used
+to install patman:
+
+$ cd tools/patman && python setup.py install
