2021-11-11arch/x86: Refactor the SMBIOS type 17 write functionSubrata Banik
List of changes: 1. Create Module Type macros as per Memory Type (i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation issue due to renaming of existing macros due to scoping the Memory Type. 2. Use dedicated Memory Type and Module type for `Form Factor` and `TypeDetail` conversion using `get_spd_info()` function. 3. Create a new API (convert_form_factor_to_module_type()) for `Form Factor` to 'Module type' conversion as per `Memory Type`. 4. Add new argument as `Memory Type` to smbios_form_factor_to_spd_mod_type() so that it can internally call convert_form_factor_to_module_type() for `Module Type` conversion. 5. Update `test_smbios_form_factor_to_spd_mod_type()` to accommodate different memory types. 6. Skip fixed module type to form factor conversion using DDR2 SPD4 specification (inside dimm_info_fill()). Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

2021-02-16device/dram: Move SPD manufacturer names out of arch/x86Patrick Rudolph
Move SPD manufacturer ID decoding to device/dram. Will be used by the following patch outside of SMBIOS scope as well.
