* device/dram: add DDR4 RCD I2C access functionsKrystian Hebel2023-08-212-1/+219
| | | | | | | | | | | | | | | | | | | | 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.

* commonlib,console,nb,sb,security: Add SPDX licenses to MakefilesMartin Roth2023-08-141-0/+1
| | | | | | | | | | | | | | | | | | | | | To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the commonlib, console, northbridge, security, and southbridge directories that don't already have an SPDX license line at the top.

* device/dram: Add kconfig options for memory typesMartin Roth2022-11-042-2/+74
| | | | | | | | | | | | | | | | | | | | | | Currently, we're building support for all memory types into every board, and letting the linker remove anything that isn't needed. This is okay, but it'd be nice to be able to build in just what's actually needed. This change adds options to specify both what is used and what is not. By doing it that way, the default values don't change, but platforms can start removing support for memory types that are not needed. When all platforms (SoCs, CPUs and/or Northbridge chips) specify what memory types they support, the defaults on the options to use a particular memory type can be set to no, and the options not to use a memory type can be removed.

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()).

It gets confused by these references in comments and strings. To fix it so that it can find the real issues, just update these as we would with real issues.

* printf: Automatically prefix %p with 0xJulius Werner2019-12-112-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.
