+description: |+
+ 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".

+ expansion modules, it is referred to as an "ASIC Development
+ 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.
