[(subset) PATCH v2 0/3] riscv: dma-mapping: unify support for cache flushes

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

This patch series is a subset from Arnd's original series [0]. Ive just
picked up the bits required for RISC-V unification of cache flushing.
Remaining patches from the series [0] will be taken care by Arnd soon.

Cheers,
Prabhakar
