+### Tools for generating SPDs for LP4x memory on TGL and JSL
+
+A set of new tools `gen_spd.go` and `gen_part_id.go` are added to automate the
+process of generating SPDs for LP4x memory and assigning hardware strap IDs for
+memory parts used on TGL and JSL based boards. The SPD data obtained from memory
+part vendors has to be massaged to format it correctly as per JEDEC and Intel MRC
+expectations. These tools take a list of memory parts describing their physical
+attributes as per their datasheet and convert those attributes into SPD files for
+the platforms. More details about the tools are added in
+[README.md](https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/uti...).
