5104 + * NOTES:
5105 + * 1. This file may be included into both C and Assembly files.
5106 + * - for .s files, please do #define _ASMLANGUAGE in your ASM file to
5107 + * avoid C data types (typedefs) below;
5108 + * - for .c files, you don't have to do anything special.
5109 + *
5110 + * 2. This file has a number of sections for each SOC subsystem. When adding
5111 + * a new constant, find the subsystem you are working on and follow the
5112 + * name pattern. If you are adding another typedef for your interface, please,
5113 + * place it with other typedefs and function prototypes.
5114 + *
5115 + * 3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
5116 + * cluttering. Include such items directly into the module's .c file or have a
5117 + * local .h file to pass data between smaller modules. This file defines only
5118 + * shared items.
