[PATCH 0/7] Add tensorflow-lite

[PATCH 0/7] Add tensorflow-lite

[Hongmei Gou]

This patch set starts from the baseline recipe at
https://github.com/nnsuite/meta-neural-network/tree/master/recipes-tensorflow/tensorflow-lite,

The major changes are listed below:
1. Ported/created recipes for all the dependencies required for tensorflow-lite 1.12
2. Installed minimal and benchmark_model binaries which have been built with the original Makefile
3. Patched Makefile to add label_image and installed the example binary and files
   (model/image/labels.txt) needed to run the example

Hongmei Gou (7):
  tensorflow-lite: add version 1.12
  flatbuffers: add version 1.10.0 needed by tensorflow-lite
  tensorflow-lite-libeigen: add the version for commit fd6845384b86
  tensorflow-lite-*: add other dependencies for tensorflow-lite 1.12
  tensorflow-lite: define dependencies via DEPENDS
  tensorflow-lite: install minimal and benchmark_model examples, and all
    .a files
  tensorflow-lite: add label_image example and install the files to run
    the example

Re: [EXTERNAL] [PATCH 4/7] tensorflow-lite-*: add other dependencies for tensorflow-lite 1.12

[Jacob Stiffler]

Why do we need to prefix all of these with "tensorflow-lite"?

Re: [EXTERNAL] [PATCH 4/7] tensorflow-lite-*: add other dependencies for tensorflow-lite 1.12

As these dependencies are specific to tensorflow-lite to get the source packages,
and therefore, I put them under the same folder of " tensorflow-lite" with the prefix.
This is also referring to the naming convention for armnn dependencies:
http://arago-project.org/git/?p=meta-arago.git;a=tree;f=meta-arago-extras/recipes-support/armnn;h=3e56a74bc783606d06fa478ea1516dd4d2375853;hb=ddb08715bf11d45886106e98ee81cbf1b3bda802

If this is not the common practice, I can create separate folders for these
dependencies under recipes-support, and remove the "tensorflow-lite" prefix.

[PATCH 5/7] tensorflow-lite: define dependencies via DEPENDS

[Hongmei Gou]

* Remove the step of downloading and copying the dependencies
* A few other changes: 1) replace AUTOREV with commit ID;
  2) remove do_configure{} which is not needed; 3) remove
  installation for flatbuffers
