From cfd700be9f5ed289fd57a9bd61e266319badcb0d Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 5 Aug 2009 09:03:54 -0500 Subject: [PATCH] fdt: Fix fdt_pci_dma_ranges handling of 64-bit ranges If the size of a region equal to 4G it can't be represnted in a 32-bit BAR so we should have marked that case as MEM64. Additionally bump the number of inbound windows up to 4 to handle the fact that Freescale PPCs that have an implicit window for CCSRBAR.
