2022-08-25util/spd_tools: Add support for LP5X SPDsRobert Zieba
This commit adds support for LP5X SPDs. The SPD format is identical to LP5 except that the memory type is set to 0x15 instead of 0x13. Since they are essentially the same, LP5/5X parts share the same parts JSON file and SPD directory. LP5X parts are distinguished by the optional `lp5x` attribute. This commit also updates two existing LP5X memory parts with the correct attribute. BUG=b:242765117 TEST=Generated SPDs, verified that SPDs generated from LP5X parts match their LP5 counterparts except for memory type byte.

Currently there are two versions of gen_part_id.go, one for LP4x and one DDR4. This change implements a unified version of this tool. The new part_id_gen.go is almost identical to the existing ddr4/gen_part_id.go. The new version was based on the ddr4 version and not the lp4x version, since the ddr4 version contains extra logic to support fixed IDs in the mem_parts_used files. The only non-trivial change from ddr4/gen_part_id.go is to include the full paths of SPD files in the generated Makefile.inc.

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.

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 LPDDR4x memory used in memory down configurations on Intel Tiger Lake (TGL) and Jasper Lake (JSL) based platforms. These tools generate SPDs following JESD209-4C specification and Intel recommendations (doc 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.
