2023-10-25include/device/dram: Add SPD lengths for DDR3 to DDR5Martin Roth
DDR2 already had a define to specify the SPD length, but other memory types did not. This led to the value being coded into other locations. Unify the definition for DDR2 to DDR5 and put the value at the top of the respective header file.

2023-08-21device/dram: add DDR4 RCD I2C access functionsKrystian Hebel
Registering Clock Driver (RCD) is responsible for driving address and control nets on RDIMM and LRDIMM applications. Its operation is configurable by a set of Register Control Words (RCWs). There are two ways of accessing RCWs: in-band on the memory channel as MRS commands ("MR7") or through I2C. Access through I2C is generic, while MRS commands are passed to memory controller registers in an implementation-specific way. See JESD82-31 JEDEC standard for full details.

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.

This makes MRS commands hardware-independent. MRS command creation is duplicated in various shapes and forms in any chipset that does DDR3. This is an effort to create a generic MRS API that can be used with any chipset. This is used in the VX900 branch.
