0013 These were the first ARM platforms officially supported by ARM Ltd.
0014 They are ARMv4, ARMv5 and ARMv6-capable using different core tiles,
0015 so the system is modular and can host a variety of CPU tiles called
0016 "core tiles" and referred to in the device tree as "core modules".

0023 - description: ARM Integrator Application Platform, this board has a PCI
0024 host and several PCI slots, as well as a number of slots for logical
0025 expansion modules, it is referred to as an "ASIC Development
0026 Motherboard" and is extended with custom FPGA and is intended for
0027 rapid prototyping. See ARM DUI 0098B. This board can physically come
0028 pre-packaged in a PC Tower form factor called Integrator/PP1 or a
0029 special metal fixture called Integrator/PP2, see ARM DUI 0169A.
