soc/amd: Print dimm_info and TYPE17_DMI_INFO to help debug incorrect values
Example 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: 0
ddr_type: 0x1a
ddr_frequency: 1200
rank_per_dimm: 1
channel_num: 0
dimm_num: 0
bank_locator: 0
mod_id: 44416
mod_type: 0x1a
bus_width: 64
serial(4): 0000
module_part_number(23): HMAA51S6AMR6N-UH ��@
dimm_size, mod_type, bus_width need to be updated so they return the
correct values. module_part_number is missing a null terminator due to
the AGESA part number being larger than the dimm_info buffer.
Example dmidecode output:
Memory Device
Array Handle: 0x0000
Error Information Handle: Not Provided
Total Width: 8 bits
Data Width: 8 bits
Size: No Module Installed
Form Factor: Unknown
Set: None
Locator: Channel-0-DIMM-0
Bank Locator: BANK 0
Type: DDR4
Type Detail: Synchronous
Speed: 1200 MT/s
Manufacturer: Hynix/Hyundai
Serial Number: 0000
Asset Tag: Not Specified
Part Number: HMAA51S6AMR6N-UH
Rank: 1
Configured Clock Speed: 1200 MT/s
Minimum Voltage: Unknown
Maximum Voltage: Unknown
Configured Voltage: Unknown
To enable the output set CONFIG_DEBUG_RAM_SETUP.
The Kconfig change is required in order to enable
CONFIG_DEBUG_RAM_SETUP, otherwise it's not a valid option.
