- 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
