2020-08-28util/gen_spd: translate DeviceBusWidth to die bus widthNick Vaccaro
If a memory part is a x16 part that has two dies and only a single rank, then the x16 describes the part width (since this solution will need to be a stacked solution) and as such, we must translate the DeviceBusWidth to the "die bus width" instead. Change DeviceBusWidth variable name to PackageBusWidth to be more descriptive BUG=b:166645306, b:160157545 TEST=run gen_spd and verify that spds for parts matching description above changed appropriately.

2020-08-28util: Add support to spd_tools for fixed idRob Barnes
For boards that have already assigned memory ids, there needs to be a way to fix parts to a specific id. After assigning all the fixed ids the tool still attempts to minimize the SPDs entries. Since a fixed ID could be anywhere, gaps can be created in the list. So an empty SPD entry is created to fill the gaps in the list until they are used.

Now that generic SPD files have the memory type prepended to the filename, they can be stored in the same location. This CL moves the generic SPDs to the new location.

2020-08-25util: Add spd_tools to generate DDR4 SPDs for TGL boardsNick Vaccaro
Serial Presence Detect (SPD) data for memory modules is used by Memory Reference Code (MRC) for training the memory. This SPD data is typically obtained from part vendors but has to be massaged to format it correctly as per JEDEC and MRC expectations. There have been numerous times in the past where the SPD data used is not always correct. In order to reduce the manual effort of creating SPDs and generating DRAM IDs, this change adds tools for generating SPD files for DDR4 memory used in memory down configurations on Intel Tiger Lake (TGL) based platforms. These tools generate SPDs following JESD79-4C and Jedec "4.1.2.L-5 R29 v103" specification. 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 DDR4 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.
