Robert Zieba de6ecd0101 util/spd_tools: Change Mendocino to use 0x13 for LP5x memory type
Mendocino supports LP5x but currently doesn't support SPDs that use the
LP5x memory type, 0x15. This commit updates set 1 SPDs, which are
currently only used for mendocino, to use 0x13 for their memory type.

BUG=b:245509394
TEST=Generated SPDs, verified that only set 1 have changed to 0x13

Caveh Jalali c762e231da util/spd_tools: Update LP5X support for ADL/RPL/MTL
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.

Robert Zieba c4d77128c5 util/spd_tools: Add support for LP5X SPDs
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.

Reka Norman bdc49b2de3 lib/Makefile.inc: Generate placeholder spd.bin in lib/Makefile.inc
When a new variant is created, it needs to have a path to its SPD binary
defined. Currently, this is done by setting SPD_SOURCES to a placeholder
SPD file, which just contains zero bytes.

To remove the need for a placeholder file, automatically generate a
single-byte spd.bin in lib/Makefile.inc when SPD_SOURCES is set to the
marker value 'placeholder'.

BUG=b:191776301
TEST=Change cappy/memory/Makefile to `SPD_SOURCES = placeholder`. Build
and check that spd.bin contains a single zero byte.

Reka Norman cf0014b145 spd: Add a placeholder SPD file to spd/
When a new variant is created, its SPD_SOURCES contains a placeholder
file, to avoid a build failure due to SPD_SOURCES being empty. Currently
these placeholder files live with the rest of the SPD files in soc and
mainboard directories, e.g.
src/soc/intel/alderlake/spd/placeholder.spd.hex

Add a similar placeholder SPD file to the new spd/ directory.

Reka Norman c65fba87b3 spd: Generate SPDs under spd/ using unified spd_gen tool
Use the new unified version of the spd_gen tool to generate all LP4x and
DDR4 SPDs, storing them in a new spd/ directory. Storing them in a
common location allows platforms with the same SPD requirements to share
SPD files, reducing duplication compared to storing SPDs in soc/ and
mainboard/ directories.

For each memory technology there are multiple sets of SPDs. Each set
corresponds to a set of platforms with different SPD requirements, e.g.
due to different memory training code expectations. A manifest file
(platforms_manifest.generated.txt) lists the platform -> set mappings.

Commands used to generate SPDs:
cp util/spd_tools/lp4x/global_lp4x_mem_parts.json.txt \
    spd/lp4x/memory_parts.json
cp util/spd_tools/ddr4/global_ddr4_mem_parts.json.txt \
    spd/ddr4/memory_parts.json
util/spd_tools/bin/spd_gen spd/lp4x/memory_parts.json lp4x
util/spd_tools/bin/spd_gen spd/ddr4/memory_parts.json ddr4
