2018-04-24soc/amd/common/block/pi/amd_late_init.c: Fix illegal memory accessRichard Spiegel
Found-by: Coverity (CID 1387031: Memory - illegal accesses (BUFFER_SIZE_WARNING)). Calling strncpy with a maximum size argument of 19 bytes on destination array "dimm->module_part_number" of size 19 bytes might leave the destination string unterminated. Fix the size parameter. BUG=b:76202696 TEST=Build and boot kahlee, using special debug code to see the output strings, which was later removed.

2018-04-12include/memory_info.h: Change serial number field from 5 bytes to 4Raul E Rangel
dimm_info.serial had a strange contract. The SPD spec defines a 4 byte serial number. dimm_info.serial required a 4 character ascii string with a null terminator. This change makes the serial field so it matches the SPD spec. smbios.c will then translate the byte array into hex and set it on the smbios table. There were only two callers that set the serial number: * haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so it already matches the new contract. * amd_late_init.c: Previously copied the last 4 characters. Requires decoding the serial number into a byte array. google/cyan/spd/spd.c: This could be updated to pass the serial number, but it uses a hard coded spd.bin. Testing this on grunt, dmidecode now shows the full serial number: Serial Number: 00000000 BUG=b:65403853 TEST=tested on grunt Change-Id: Ifc58ad9ea4cdd2abe06a170a39b1f32680e7b299 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Reviewed-on: https://review.coreboot.org/25343 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2018-04-11soc/amd: Fix generating SMBIOS Type 17Raul E Rangel
The converter was setting SMBIOS values when dimm_info expects SPD values. dmidecode now shows the following: Memory Device Array Handle: 0x0000 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 8192 MB Form Factor: SODIMM Set: None Locator: Channel-0-DIMM-0 Bank Locator: BANK 0 Type: DDR4 Type Detail: Synchronous Speed: 933 MT/s Manufacturer: Hynix/Hyundai Serial Number: 00000000 Asset Tag: Not Specified Part Number: HMAA51S6AMR6N-UH Rank: 1 Configured Clock Speed: 933 MT/s Minimum Voltage: Unknown Maximum Voltage: Unknown Configured Voltage: Unknown Example debug output: AGESA TYPE 17 DMI INFO: Handle: 1 TotalWidth: 64 DataWidth: 64 MemorySize: 8192 DeviceSet: 0 Speed: 1200 ManufacturerIdCode: 44416 Attributes: 1 ExtSize: 0 ConfigSpeed: 933 MemoryType: 0x1a FormFactor: 0xd DeviceLocator: DIMM 0 BankLocator: CHANNEL A SerialNumber(8): ' 00000000' PartNumber(20): 'HMAA51S6AMR6N-UH ' CBMEM_ID_MEMINFO: dimm_size: 8192 ddr_type: 0x1a ddr_frequency: 933 rank_per_dimm: 1 channel_num: 0 dimm_num: 0 bank_locator: 0 mod_id: 44416 mod_type: 0x4 bus_width: 3 serial: 0x00000000 module_part_number(18): 'HMAA51S6AMR6N-UH ' The serial number we get from AGESA (at least on my board) is always 00000000.

2018-02-26soc/amd/common/block/pi/amd_late_init.c: Fix part numberRichard Spiegel
Kahlee DIMM have invalid string when it comes to part number (bytes 0x149-0x15c). We currently force a NA string, but grunt has the proper strings. Just let the string go through, and a second commit within smbios.c will be responsible for testing the string and taking proper action. BUG=b:73122207 TEST=Build, boot and record serial output for kahlee while injecting different strings to dmi17->PartNumber. Remove string injection before committing.

2018-02-16soc/amd/common/block/pi/amd_init_late.c: Transfer memory info to cbmemRichard Spiegel
SMBIOS structure type 17 is not being generated because memory info is not being stored to cbmem. This has to happen after AGESA AmdInitLate has run, but before SMBIOS is generated. There's a need to convert format between AGESA generated info, and what is required in cbmem. Create a procedure that transfers information between AGESA and cbmem, and call it from agesawrapper_post_device() after AmdLateInit is called. BUG=b:65403853 TEST=build and run kahlee, verify if SMBIOS structure type 17 is being generated, and if associated strings are what should be expected.
