ARM Ltd. RealView is a blanket name for development packages from ARM including for example the "RealView Developer Suite" (RVDS) which includes a compiler. However to most developers the RealView is synonymous with an evaluation board which has it's machine set-up available in the kernel arch/arm/mach-realview.
The RealView siblings are:
- mach-integrator ARM Integrator Info also named "RealView Integrator" boards are the oldest and support ARM7, ARM9 and ARM10 CPUs
- mach-versatile ARM Versatile also named "RealView Versatile" is middle-age and supports a family of ARM9 CPUs
- mach-realview ARM RealView - the machine configurations named simply RealView are the newest ones supporting ARM11 and Cortex A8/A9 (CPUv6,CPUv7) CPUs, the product name for these is actually also "RealView Versatile" but traditionally have their own entry in the kernel tree
These all have own machine entries in the ARM arch kernel tree.
All these boards come in a black square box with PCI card slots, and support using PCI peripherals and e.g. a PS2 keyboard and mouse so they can more or less be used as desktop computers if so desired.
However RealView boards are quite expensive and few people can afford them, while they are still the preferred choice for companies wanting to work with the very latest ARM cores.
