From: Nicolas Pitre Date: Sat, 3 Sep 2011 01:05:10 +0000 (-0400) Subject: ARM: mach-prima2: move ARM_DMA_ZONE_SIZE to mdesc->dma_zone_size X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=98b0124f0e2b88ec74cbd9345cf6195e527ce251;p=linux-beck.git ARM: mach-prima2: move ARM_DMA_ZONE_SIZE to mdesc->dma_zone_size Original comment: Restrict DMA-able region to workaround silicon limitation. The limitation restricts buffers available for DMA to SD/MMC hardware to be below 256MB.
