This updates the SPD utility and generated SPDs for LP5X to use memory
type code 0x15 (LPDDR5X) instead of 0x13 (LPDDR5). This is done based on
Intel Tech Advisory Doc ID #616599 dated May 2022, page 15.
SPDs were regenerated with:
"util/spd_tools/bin/spd_gen spd/lp5/memory_parts.json lp5"
This only affects the SPDs for 2 memory parts for Intel SoCs and the
only board referencing these is rex.

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

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. E.g. instead of
SPD_SOURCES += lp4x-spd-1.hex
the full path relative to the coreboot root directory is included:

Currently there are two versions of spd_tools: one for LP4x and one for
DDR4. This change is the first step in unifying these into a single
tool.
This change implements a unified version of the spd_gen tool, by
combining the functionality currently in lp4x/gen_spd.go and
ddr4/gen_spd.go. The unified version takes the memory technology as an
argument, and generates SPD files for all platforms supporting that
technology.
BUG=b:191776301
TEST=Compare the SPDs generated by the old and new versions of the tool
for all supported platforms. For reference, the test script used is

CB:52586 ("util/spd_tools: Add MT53E1G32D2NP-046 WT:B LPDDR4 config")
incorrectly set ranks per channel to 1. However, MT53E1G32D2NP-046 WT:B
part has 2 channels per die and 2 physical dies. Each channel in each die shares DQ-DQS lines with the channel in other die and uses separate CS lines. Thus, number of ranks per channel is 2.
This change fixes the attribute ranksPerChannel for MT53E1G32D2NP-046 WT:B in LP4x global config by setting it to 2.

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.

As per JEDEC spec, manufacturer part name should be set to
blank (0x20). This change updates gen_spd.go to set bytes 329-348 as
0x20 and regenerates SPDs for TGL and JSL.

This change adds a JSON file (`global_lp4x_mem_parts.json.txt`)
containing global list of LP4x memory parts to live along with the spd
tools since the part information is not really any SoC or mainboard
dependent and comes directly from the part datasheet. It can be shared
by mainboards based on different platforms supported by the tools.

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 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.
