2023-08-28src/device/dram/Makefile.inc: specify one file per lineSergii Dmytruk
A trivial follow-up on CB:67060. This makes contents of the file look a bit less regular, but more like the rest Makefile.inc in the code base.

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.

2023-08-14commonlib,console,nb,sb,security: Add SPDX licenses to MakefilesMartin Roth
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.

2022-11-04device/dram: Add kconfig options for memory typesMartin Roth
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.
