From: Kevin Cernekee Date: Mon, 9 Jul 2012 01:41:18 +0000 (+0000) Subject: MIPS: BCM63XX: Move DMA descriptor definition into common header file X-Git-Tag: v3.7-rc1~77^2~7^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=932e30b6ea8d2ce5a5d60b799f5c088547f105b3;p=profile%2Fivi%2Fkernel-x86-ivi.git MIPS: BCM63XX: Move DMA descriptor definition into common header file The "IUDMA" engine used by bcm63xx_enet is also used by other blocks, such as the USB 2.0 device. Move the definitions into a common file so that they do not need to be duplicated in each driver.
