From 6d8ff10c3ab1e3d4a40788442f1369e868103e43 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 4 Jun 2007 11:56:42 -0500 Subject: [PATCH] [POWERPC] Let subordinate transparent bridges be transparent. In pcibios_fixup_bus(), bridges that are subordinate to transparent bridges were still relocating their IORESOURCE_IO and IO_RESOURCE_MEM start and end values. Fix this by preventing the transparent bridge from relocating the start and end values, thus allowing the subordinate non-transparent bridge full molestation rights.
