[By Steven Scholz <steven.scholz@imc-berlin.de>, 16 Aug 2004]Since the cpu/ directory gets clobbered with peripheral driver code Istarted cleaning up cpu/arm920t.I introduced the concept of Soc (system on a chip) into the ./cpudirectory. That means that code that is cpu (i.e. core) specificresides in	cpu/$(CPU)/and code that is specific to some SoC (i.e. vendor specificperipherals around the core) is moved into	cpu/$(CPU)/$(SOC)/Thus a library/archive "cpu/$(CPU)/$(SOC)/lib$(SOC).a" will be buildand linked. Examples will be	cpu/arm920t/imx/	cpu/arm920t/s3c24x0One can select an SoC by passing the name of it to ./mkconfig justlike	@./mkconfig $(@:_config=) arm arm920t vcma9 mpl s3c24x0If there's no VENDOR field (like "mpl" in the above line) one has topass NULL instead:	@./mkconfig $(@:_config=) arm arm920t mx1ads NULL imx
