+  These were the first ARM platforms officially supported by ARM Ltd.
+  They are ARMv4, ARMv5 and ARMv6-capable using different core tiles,
+  so the system is modular and can host a variety of CPU tiles called
+  "core tiles" and referred to in the device tree as "core modules".

+          Motherboard" and is extended with custom FPGA and is intended for
+          rapid prototyping. See ARM DUI 0098B. This board can physically come
+          pre-packaged in a PC Tower form factor called Integrator/PP1 or a
+          special metal fixture called Integrator/PP2, see ARM DUI 0169A.
