From aae123c6292b4463d31a0836e1de13817f9859da Mon Sep 17 00:00:00 2001 From: hauke Date: Mon, 5 Aug 2013 16:17:05 +0000 Subject: kernel: fix DMA error when BCM4331 is connected to BCM4706 The BCM4331 supports a PCIe max request size of 512 bytes and uses that, but the PCIe controller in the BCM4706 just supports 128 Bytes and that causes a DMA error for packages bigger than 126 bytes. This fixes the problem by setting the BCM4331 also to 128 Bytes.
