According to the MPC8260 User's Manual, PCI_MODE signal should be reflected in SCCR register, and local bus pins configuration is taken from HRCW and appears in SIUMCR. For some reason it does not work this way, so the only possibility to detect if the board is configured in PCI mode is to check the BCSR. This patch sets SCCR and SIUMCR according to the BCSR.
