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