There used to be two versions of the RealView EB 11MPCore:
- arm-realview-eb-11mp.dts: the most common variant supported by
QEMU with the revision C core tile
- arm-realview-eb-revb.dts: for the variant with the elder revision
B core tile.
As it turns out that there are also a few variants of the
baseboard, unrelated to the coretile, and that these can of
course be mounted on top of each other in all permutations, we
create:
- arm-realview-eb-11mp.dts: the most common variant supported by
QEMU with the pre-revision D baseboard and the revision C core
tile.
- arm-realview-eb-11mp-bbrevd.dts: the revision D baseboard
with the common revision C core tile.
- arm-realview-eb-11mp-ctrevb.dts: the pre-revision D baseboard
with the revision B core tile.
- arm-realview-eb-11mp-bbrevd-ctrevb.dts: the revision D baseboard
with the revision B core time.
Or as a table:
| Core tile: C | Core tile: B
-----------+----------------------------+-----------------------------------
Baseboard: | |
pre-D |arm-realvie-eb-11mp | arm-realview-eb-11mp-ctrevb
-----------+----------------------------+-----------------------------------
Baseboard: | |
D |arm-realview-eb-11mp-bbrevd | arm-realview-eb-11mp-bbrevd-ctrevb
-----------+----------------------------+-----------------------------------
