util/mb/google: Add spd_tools to generate SPDs for TGL boards
This change adds tools for generating SPD files for LPDDR4x memory used in memory down configurations on Intel Tiger Lake(TGL) based Chrome OS platforms. These tools generate SPDs following JESD209-4C specification and Intel recommendations(doc #616599) for LPDDR4x SPD.
Two tools are provided: * gen_spd.go: Generates de-duplicated SPD files using a global memory part list provided by the mainboard in JSON format. Additionally, generates a SPD manifest file(in CSV format) with information about what memory part from the global list uses which of the generated SPD files.
* gen_part_id.go: Allocates DRAM strap IDs for different LPDDR4x memory parts used by the board. Takes as input list of memory parts used by the board (with one memory part on each line) and the SPD manifest file generated by gen_spd.go. Generates Makefile.inc for integrating the generated SPD files in the coreboot build.
