2020-10-03Revert "util/spd_tools: output binaries instead of hexdumps"Rob Barnes
This reverts commit f23794cf04030bb8d1d7ebe0a3634dffd092e2f7. Reason for revert: This change breaks compatibility if the changes in CB:44775 are not also included. CB:44775 is still under discussion, so revert this change to make spd_tools usable again.

2020-09-08util/spd_tools: output binaries instead of hexdumpsMichael Niewöhner
Instead of generating hexdumps, output binary SPD files since we plan to convert all hex SPD files to binary. Also adjust the file extension where needed. Test: compared generated binaries with converted binaries from hex files Change-Id: Ie99d108ca90758d09dbefad20fe6c9f7fc263ef1 Signed-off-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/44878 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
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.

2020-08-28util: volteer/dedede: move generic SPDs to common locationNick Vaccaro
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. Change the ddr4 gen_part_id.go and gen_spd.go tools to use "ddr4_spd_manifest.generated" instead of "spd_manifest.generated". Change the lpddr4x gen_part_id.go and gen_spd.go tools to use "lp4x_spd_manifest.generated" instead of "spd_manifest.generated". Move TGL DDR4 and LPDDR4x generic SPDs into a common location. Move JSL DDR4 and LPDDR4x generic SPDs into a common location. Change the volteer/spd/Makefile.inc to use the new path for the spds. Change the dedede/spd/Makefile.inc to use the new path for the spds. BUG=b:165854055 TEST="emerge-volteer coreboot" and verify all variants build correctly.
