This seems wrong still: The clusters and cores do not have unique
numbers. I believe the code will not work correctly, and it won't
be compliant with the binding from patch 2.
I think the right way here would be to use
arm,associativity = <0 2 47>;
for cpu@20f, and
arm,associativity = <1 3 48>;
for cpu@10000. Your previous version used the numbers from
the reg property, which should be fine as well if that helps:
arm,associativity = <0x0 0x200 0x20f>;
arm,associativity = <0x10000 0x10000 0x10000>;
which should have the same effect as above, as long as the code
can handle the numbers not being consecutive.
