Subject: [U-Boot] [PATCH] net: force PKTALIGN to ARCH_DMA_MINALIGN
Date: Wed, 14 Mar 2012 14:35:56 -0700	[thread overview]
Message-ID: <1331760956-3901-1-git-send-email-eric.nelson@boundarydevices.com> (raw)
In-Reply-To: <http://lists.denx.de/pipermail/u-boot/2012-March/120205.html>

This will prevent the need for architectures whose DMA alignment
is greater than 32 to have bounce buffers.
