Subject: arch, base: Move arm AtomicOpFunctor into the generic header
X-Git-Tag: v19.0.0.0~127
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3225c4075b0ddfd83a9f7a220d39740f86a64f16;p=gem5.git

arch, base: Move arm AtomicOpFunctor into the generic header

These AtomicGenericxOp functors are not arm specific:
They just define a set of different functors depending
on the number of operands they are using.
