From 35db1c6d34b57ae15e99cf03c8e8f8a6148d74f3 Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Fri, 21 Nov 2008 19:24:22 -0600 Subject: [PATCH] drivers/fsl_pci_init: Fix inbound window mapping bug The current code will cause the creation of a 4GB window starting at 0 if we have more than 4GB of RAM installed, which overlaps with PCI_MEM space and causes pci_bus_to_phys() to return erroneous information. Limit the size to 4GB - 1; which causes the code to create one 2GB and one 1GB window instead.
