 Changes since U-Boot 1.1.1:
 ======================================================================
 
+* Patch by Steven Scholz, 16 Aug 2004:
+  - Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
+  - creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
+  - moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
+  - moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
+    into cpu/arm920t/$(SOC)/
+
 * Patches by Sean Chang, 09 Aug 2004:
   - Added support for both 8 and 16 bit mode access to System ACE CF
     through MPU.

+[By Steven Scholz <steven.scholz@imc-berlin.de>, 16 Aug 2004]
+
+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
