From 6bb2ae535f2eee0334802724a542701bd969d055 Mon Sep 17 00:00:00 2001 From: Gerhard Pircher Date: Fri, 19 Jun 2009 11:42:36 +0000 Subject: [PATCH] powerpc/amigaone: Limit ISA I/O range to 4k in the device tree The kernel reserves the I/O address space from 0x0 to 0xfff for legacy ISA devices. Change the ranges property for the PCI2ISA bridge to match the kernels behavior, even if the ranges property isn't used for now.
