From 54648985e2a64e29784e3ed37cd45b637305cd65 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 20 Apr 2010 10:21:12 -0500 Subject: [PATCH] 85xx/mpc8536ds: Use is_serdes_configured() to determine of PCIe enabled The new is_serdes_configured covers a broader range of devices than the PCI specific code. Use it instead as we convert away from the is_fsl_pci_cfg() code. Additionally move to setting LAWs for PCI based on if its configured. Also updated PCI FDT fixup code to remove PCI controllers from dtb if they are configured.
