+ *
+ * These are const, typedef, and api definitions for tnetd73xx.
+ *
+ * NOTES:
+ * 1. This file may be included into both C and Assembly files.
+ * - for .s files, please do #define _ASMLANGUAGE in your ASM file to
+ * avoid C data types (typedefs) below;
+ * - for .c files, you don't have to do anything special.
+ *
+ * 2. This file has a number of sections for each SOC subsystem. When adding
+ * a new constant, find the subsystem you are working on and follow the
+ * name pattern. If you are adding another typedef for your interface, please,
+ * place it with other typedefs and function prototypes.
+ *
+ * 3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
+ * cluttering. Include such items directly into the module's .c file or have a
+ * local .h file to pass data between smaller modules. This file defines only
+ * shared items.
