Based on updated data from:

which is based on PMU event descriptions from the Arm Neoverse V1
Technical Reference Manual.

This adds the following missing events:
ASE_INST_SPEC
SVE_INST_SPEC
SVE_PRED_SPEC
SVE_PRED_EMPTY_SPEC
SVE_PRED_FULL_SPEC
SVE_PRED_PARTIAL_SPEC
SVE_LDFF_SPEC
SVE_LDFF_FAULT_SPEC
FP_SCALE_OPS_SPEC
FP_FIXED_OPS_SPEC

It also moves REMOTE_ACCESS from other.json to memory.json.

Any specific reason why? I see that neoverse n2 and a76-n1 still use "other" json for REMOTE_ACCESS. Nicer to be consistent.

Thanks John, I agree on consistency.

I think memory is a better categorisation (for all CPUs), and this is consistent with what I submitted for various Cortex CPUs a while back.

I'd be happy to remove the REMOTE_ACCESS change here and update (or not) REMOTE_ACCESS for Neoverse separately.
