+
+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
