Subject: [RFC PATCH V4 3/6] RISC-V: Support a new config option for non-coherent DMA
Date: Sat, 11 Sep 2021 17:21:36 +0800	[thread overview]
Message-ID: <20210911092139.79607-4-guoren@kernel.org> (raw)
In-Reply-To: <20210911092139.79607-1-guoren@kernel.org>

From: Atish Patra <atish.patra@wdc.com>

In future, there will be more RISC-V platforms with non-coherent DMA.
Instead of selecting all the required config options in every soc, create
a new config that selects all the required configs related non-coherent
DMA.
