### Intel Xeon Scalable Processor support is now considered mature
Intel Xeon Scalable Processor (Xeon-SP) family [1] is designed
primarily to serve the needs of the server market.
coreboot support for Xeon-SP is in src/soc/intel/xeon_sp directory.
This release has support for SkyLake-SP (SKX-SP) which is the 2nd
generation, and for CooperLake-SP (CPX-SP) which is the 3rd generation
or the latest generation [2] on market.
With this release, the codebase for multiple generations of Xeon-SP
were unified and optimized:
* SKX-SP SoC code is used in OCP TiogaPass mainboard [3]. Support for
this board is in Proof Of Concept Status.
* CPX-SP SoC code is used in OCP DeltaLake mainboard. Support for
this board is in DVT (Design Validation Test) exit equivalent status.
Features supported, (performance/stability) test scopes, known issues,
features gaps are described in [4].
