- =========================================
- PART-SPECIFIC SOURCE COMPARTMENTALISATION
- =========================================
-
-The sources for various parts are compartmentalised at two different levels:
-
- (1) Processor level
-
- The "processor level" is a CPU core plus the other on-silicon
- peripherals.
-
- Processor-specific header files are divided among directories in a similar
- way to the CPU level:
-
- (*) include/asm-mn10300/proc-mn103e010/
-
- Support for the AM33v2 CPU core.
-
- The appropriate processor is selected by a CONFIG_MN10300_PROC_YYYY option
- from the "Processor support" choice menu in the arch/mn10300/Kconfig file.
-
-
- (2) Unit level
-
- The "unit level" is a processor plus all the external peripherals
- controlled by that processor.
-
- Unit-specific header files are divided among directories in a similar way
- to the CPU level; not only that, but specific sources may also be
- segregated into separate directories under the arch directory:
-
- (*) include/asm-mn10300/unit-asb2303/
- (*) arch/mn10300/unit-asb2303/
-
- Support for the ASB2303 board with an ASB2308 daughter board.
-
- (*) include/asm-mn10300/unit-asb2305/
- (*) arch/mn10300/unit-asb2305/
-
- Support for the ASB2305 board.
-
- The appropriate processor is selected by a CONFIG_MN10300_UNIT_ZZZZ option
- from the "Unit type" choice menu in the arch/mn10300/Kconfig file.
-

-COMPILE TIME
-============
-
-When the kernel is compiled, symbolic links will be made in the asm header file
-directory for this arch:
-
- include/asm-mn10300/proc => include/asm-mn10300/proc-YYYY/
- include/asm-mn10300/unit => include/asm-mn10300/unit-ZZZZ/
-
-So that the header files contained in those directories can be accessed without
-lots of #ifdef-age.
-
-The appropriate arch/mn10300/unit-ZZZZ directory will also be entered by the
-compilation process; all other unit-specific directories will be ignored.
