Subject[RFC 0/5] ARC: handle DSP presence in HW
Date
Arc processors may have DSP extension which is optional.
In this patch series we:
* Handle issues caused by DSP extension presence in HW
* Add optional support for DSP-enabled applications in
userspace (with optional AGU extension support)
* Do minor cleanups

Eugeniy Paltsev (5):
ARC: pt_regs: remove hardcoded registers offset
ARC: add helpers to sanitize config options
ARC: handle DSP presence in HW
ARC: add support for DSP-enabled userspace applications
ARC: allow userspace DSP applications to use AGU extensions
