Subject: arm,dev: remove PMU assertion hit on reset
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edbf748181bdd3ac86838e7c55d98a336b285e01;p=gem5.git

arm,dev: remove PMU assertion hit on reset

Remve the assertion that we always need to add a delta larger than
zero as that does not seem to be true when we hit it in the
'PMU reset cycle counter to zero' case.
