[By Steven Scholz , 16 Aug 2004] Since the cpu/ directory gets clobbered with peripheral driver code I started cleaning up arch/arm/cpu/arm920t. I introduced the concept of Soc (system on a chip) into the ./cpu directory. That means that code that is cpu (i.e. core) specific resides in $(CPUDIR)/ and code that is specific to some SoC (i.e. vendor specific peripherals around the core) is moved into $(CPUDIR)/$(SOC)/ Thus a library/archive "$(CPUDIR)/$(SOC)/lib$(SOC).a" will be build and linked. Examples will be arch/arm/cpu/arm920t/imx/ arch/arm/cpu/arm920t/s3c24x0 One can select an SoC by passing the name of it to ./mkconfig just like @./mkconfig $(@:_config=) arm arm920t vcma9 mpl s3c24x0 If there's no VENDOR field (like "mpl" in the above line) one has to pass NULL instead: @./mkconfig $(@:_config=) arm arm920t mx1ads NULL imx
