The ARM RealView Evaluation Baseboards are basically these: - The original ARMv5 EB board with an ARM926EJ-S, ARM1136 or ARM1176 core tile here described in arm-realview-eb.dts no matter which of these core tiles is being used. This can be emulated by QEMU "realview-eb" machine, which by default will have the ARM926EJ-S core tile. - The same board with one of three MPCore Core tiles: ARM11MPCore, not to be confused with the similar ARM PB11MPCore ARM11MPCore test system. This exist in two revisions: - Revision A modeled in arm-realview-eb-11mp.dts - Revision B modeled arm-realview-eb-11mp-revb.dts Revision B can be emulated by the QEMU "realview-eb-mpcore" machine, but to match the hardware also the argument -smp cpus=4 must be passed so that it has four CPU cores, like the hardware. There is also evidently from the code in the kernel a Cortex-A9 core tile for the EB, and this is modeled in arm-realview-eb-a9mp.dts based on the kernel boardfile. I have not found a user guide for this EB core tile on the ARM website and it seems uncommon. It is however included for completeness.
