From d7283c11f7e87e40c44bbffc4397309ef8bc5c7b Mon Sep 17 00:00:00 2001 From: Jay Agarwal Date: Fri, 9 Aug 2013 16:49:31 +0200 Subject: ARM: dts: tegra: Increase prefetchable PCI memory space Instead of evenly splitting the 512 MiB area between prefetchable and non-prefetchable memory spaces, increase the prefetchable memory space to 384 MiB while at the same time decreasing the non-prefetchable memory space to 128 MiB. This is a more useful default as most PCIe devices require more prefetchable than non-prefetchable memory.
