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.
