From 8f89549d3c7d41643337662947cfdb2329bd030b Mon Sep 17 00:00:00 2001 From: Jonathan Zhang Date: Thu, 16 Jan 2020 11:16:45 -0800 Subject: soc/intel: Add Intel Xeon Scalable Processor support This patch adds support for Intel Xeon-SP. This patch is developed and verified with Skylake Scalable Processor, which is a processor in Xeon-SP family. The code is expected to be reusable for future geneations of Xeon-SP processors, and will be updated with smaller targeted patches accordingly, to add support for additional Xeon-SP processors, to add features, and to improve the code base. The Skylake-SP FSP is based on FSP 2.0. The FSP is a proof-of-concept build. The binary is not shared in public, when this patch is upstreamed.
