-## About Granite Rapids n-1 FSP headers
-
-This is a set of stub FSP headers for Granite Rapids server, which will
-be forward compatible with the formal Granite Rapids FSP headers which
-will be opensource at a later stage. For the n-1 FSP headers, there are
-no corresponding n-1 FSP binaries. To pass build, users need to use stub
-binaries which could be generated in arbitrary ways.  Granite Rapids n-1
-FSP headers are at: `src/vendorcode/intel/fsp/fsp2_0/graniterapids`.
