/**
 * @file
 * @brief Register map for the STM32 family of chips
 *
 * This header file should only contain register definitions and
 * functionality that are common to all STM32 chips.
 * Any chip/family specific macros must be placed in their family
 * specific registers file, which is conditionally included at the
 * end of this file.
 * Include this file directly for all STM32 register definitions.
 *
 * ### History and Reasoning ###
 * In a time before chip family register file separation,
 * long long ago, there lived a single file called `registers.h`,
 * which housed register definitions for all STM32 chip family and variants.
 * This poor file was 3000 lines of register macros and C definitions,
 * swiss-cheesed by nested preprocessor conditional logic.
 * Adding a single new chip variant required splitting multiple,
 * already nested, conditional sections throughout the file.
 * Readability was on the difficult side and refactoring was dangerous.
 *
 * The number of STM32 variants had outgrown the single registers file model.
 * The minor gains of sharing a set of registers between a subset of chip
 * variants no longer outweighed the complexity of the following operations:
 * - Adding a new chip variant or variant feature
 * - Determining if a register was properly setup for a variant or if it
 *   was simply not unset
 *
 * To strike a balance between shared registers and chip specific registers,
 * the registers.h file remains a place for common definitions, but family
 * specific definitions were moved to their own files.
 * These family specific files contain a much reduced level of preprocessor
 * logic for variant specific registers.
 *
 * See https://crrev.com/c/1674679 to witness the separation steps.
