Local bus initialisation is under #ifdef CFG_LSDRAM_BASE so if this is
not defined, the local bus initialisation code won't even be compiled in.

You have to select PCI or Local bus using jumper JP9. The jumper's
setting is reflected in BCSR3 and used by the code to set some
registers. If JP9 selects Local bus but you try to initialise PCI it
should fail.
