+Entry: intel-fsp-s: Entry containing Intel Firmware Support Package (FSP) silicon init

+Properties / Entry arguments:
+    - filename: Filename of file to read into entry
+
+This file contains a binary blob which is used on some devices to set up
+the silicon. U-Boot executes this code in U-Boot proper after SDRAM is
+running, so that it can make full use of memory. Documentation is typically
+not available in sufficient detail to allow U-Boot do this this itself.
+
+An example filename is 'fsp_s.bin'
+
+See README.x86 for information about x86 binary blobs.
