[U-Boot] [PATCH v2 1/2] 85xx/mpc8536ds: Use is_serdes_configured() to determine of PCIe enabled

Wed Apr 28 10:05:47 CEST 2010
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.

* Added code to handle dynamic LAW setup for PCI
* Added removing of PCI controller nodes from dtb if not cfg
