| | | | | | | | | | | | | | | | | | | | 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.

* lib/Makefile.inc: Generate placeholder spd.bin in lib/Makefile.incReka Norman2021-09-231-32/+0
| | | | | | | | | | | | | | | | | | | | | 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.

* spd: Add a placeholder SPD file to spd/Reka Norman2021-09-201-0/+32
| | | | | | | | | | | | | | | | | | | 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.

* spd: Generate SPDs under spd/ using unified spd_gen toolReka Norman2021-09-2036-0/+1612
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 BUG=b:191776301 TEST=None Signed-off-by: Reka Norman <rekanorman@google.com> Change-Id: Iac82847a1a0c1f2e7271d0d3b3a7261849813a24 Reviewed-on: https://review.coreboot.org/c/coreboot/+/57514 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com>
