-Subject: [PATCH 1/2] Add support for Blackfin
-
-Taken upstream from
-https://github.com/atgreen/libffi/commit/213ed15c70e72d666154c08e2b41dae3f61f20d3. Will
-be part of the upcoming 3.0.12 release.
-
-We have kept the part of the patches changing configure and
-Makefile.in in order to avoid having to autoreconf the package, which
-requires autoconf 2.68.
-
-Code written by Alexandre Keunecke.
-
-Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
