Subject: [PATCH v4 2/5] RISC-V: Add preprocessor directive for swiotlb
Date: Wed,  3 Oct 2018 11:09:59 +0800	[thread overview]
Message-ID: <0aaabb05426a360f71cbc7a910e2c613d3a3891c.1538535528.git.zongbox@gmail.com> (raw)
In-Reply-To: <cover.1538535527.git.zongbox@gmail.com>

On RV32, it doesn't select the SWIOTLB, only RV64 support swiotlb now.
