The TianoCore EDKII project has introduced a Core CI infrastructure using TianoCore EDKII Tools PIP modules: * https://pypi.org/project/edk2-pytool-library/ * https://pypi.org/project/edk2-pytool-extensions/ More information on configuring the environment and running the builds can be found in edk2\.pytool\Readme.md This patch fixes the issues reported by the CI system mainly around fixing typo errors and package dec and dsc files. A subsequent patch enables the CI builds for the DynamicTablesPkg. Signed-off-by: Sami Mujawar <sami.mujawar@arm.com> Reviewed-by: Alexei Fedorov <Alexei.Fedorov@arm.com>
