Subject: tinycbor: Update import to v0.4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=82e786bda7b2749b76d59c7e43181c55f1a950a5;p=contrib%2Fiotivity.git

tinycbor: Update import to v0.4

Needed for IoTivity 1.2.1 and later

git "module" was converted to patch this way:

  git clone https://github.com/01org/tinycbor.git -b v0.4 extlibs/tinycbor/tinycbor
  rm -rf extlibs/tinycbor/tinycbor/.git
  git add -f  extlibs/tinycbor/tinycbor/
  git commit -sm 'tinycbor: Update import to v0.4' extlibs/tinycbor/tinycbor/

It is strongly recommended to rely on scons instead,
 if not possible, this change workaround this.

For more details about building IoTivity please check:
https://wiki.iotivity.org/build
