From 2a3b9b2ad5849fa3980196f8733548b8976d804a Mon Sep 17 00:00:00 2001 From: Jeremy Compostella Date: Thu, 26 Sep 2024 10:50:09 -0700 Subject: soc/intel/pantherlake: Comply with the no typedef coding style rule As https://doc.coreboot.org/contributing/coding_style.html#typedefs states: "In general, a pointer, or a struct that has elements that can reasonably be directly accessed should never be a typedef". This commit makes the Intel Panther Lake SoC code comply with this by using explicitly `struct soc_intel_pantherlake_config' in the soc/intel/pantherlake code as I have been suggested to for the `fsp_params.c' files. The rule being the rule and consistency across a project matters more than personal preferences. The documentation lists five exceptions and none on them cover the use of `config_t' instead `struct soc_intel_pantherlake' but I believe it does not make the code better for the following three reasons: 1. It is repetitive, make the line longer and the code is in soc/intel/pantherlake so obviously the config_t data structure is the pantherlake soc configuration. 2. It makes re-usability from one generation to another unnecessarily harder. 3. This config_t abstraction is required for and used by some common block code anyway. Hence, we end-up with some code using `config_t' and other using the final structure which break the consistency of the code when the project in looked as a whole.
