From b9d961550ce07951b472ae558281e288413ab445 Mon Sep 17 00:00:00 2001 From: Ionela Voinescu Date: Fri, 12 Dec 2014 13:53:22 +0000 Subject: urara: add support for DMA coherent memory area The information about the DMA memory area is further passed through the coreboot table to the payload. BUG=chrome-os-partner:31438 TEST=tested on Pistachio FPGA; DMA memory area was used to test the functionality of the DWC2 USB controller driver; behavior was as expected.
