Subject: [PATCH 12/20] mci: allocate DMA-able memory
Date: Mon, 31 May 2021 09:38:13 +0200	[thread overview]
Message-ID: <20210531073821.15257-13-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210531073821.15257-1-a.fatoum@pengutronix.de>

Doesn't yet make a difference, but in a future commit, RISC-V will use a
64-bit alignment for the sector buffers by defining a custom dma_alloc.

Prepare for this.
