+Subject: [PATCH] MIPS: AR71xx: Fix AR71XX_PCI_MEM_SIZE
+
+commit fe950df70013a9f3368918aab697eec15f80ac67 upstream.
+
+The base address of the PCI memory is 0x10000000 and the base address of the
+PCI configuration space is 0x17000000 on the AR71xx SoCs.
+
+The AR71XX_PCI_MEM_SIZE is defined as 0x08000000 which is wrong because that
+overlaps with the configuration space.  This patch fixes the value of the
+AR71XX_PCI_MEM_SIZE constant, in order to avoid this resource conflicts.
