T
Li, Xun 60d36e0de7 Linux 2.10 Open Source Gold Release 
Provided a reproducible SDK.
Supported new OS: RHEL 8.1, CentOS 8.1 and Fedora 31.
Supported user to specify platform id in PCK Cert ID Retrieval Tool’s command line option.
Added ability to execute Platform Cert ID Retrieval Tool on multi-package platforms without
  loading enclaves. PCCS now supports this functionality. The platform still needs to support
  SGX.
Updated Platform Cert ID Retrieval Tool and Multi-package registration tool to align with BIOS
  platform manifest changes.
Added .deb and .rpm installers for Platform Cert ID Retrieval Tool and Multi-package
  Registration Agent.
Fixed bugs.
