Since the cpu/ directory gets clobbered with peripheral driver code I
-started cleaning up cpu/arm920t.
+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
- cpu/$(CPU)/
+ $(CPUDIR)/
and code that is specific to some SoC (i.e. vendor specific
peripherals around the core) is moved into
- cpu/$(CPU)/$(SOC)/
+ $(CPUDIR)/$(SOC)/
-Thus a library/archive "cpu/$(CPU)/$(SOC)/lib$(SOC).a" will be build
+Thus a library/archive "$(CPUDIR)/$(SOC)/lib$(SOC).a" will be build
and linked. Examples will be
- cpu/arm920t/imx/
- cpu/arm920t/s3c24x0
+ 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
