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

23      - description: ARM Integrator Application Platform, this board has a PCI
24          host and several PCI slots, as well as a number of slots for logical
25          expansion modules, it is referred to as an "ASIC Development
26          Motherboard" and is extended with custom FPGA and is intended for
27          rapid prototyping. See ARM DUI 0098B. This board can physically come
28          pre-packaged in a PC Tower form factor called Integrator/PP1 or a
29          special metal fixture called Integrator/PP2, see ARM DUI 0169A.
