Support has being added through earlier commits to build capsules and embed the public key needed for capsule authentication as part of u-boot build. From the testing point-of-view, this means the input files needed for the above have to be setup before invoking the build. Set this up in the pytest configuration file for testing the capsule update feature. Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org> --- Changes since V2: * New patch for setting up the capsule files in the pytest setup before initiation of u-boot build. test/py/conftest.py | 87 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 87 insertions(+)
