I am having trouble with my PQ2FADS-ZU board with a PQ2 8280
processor that when the localbus is put into PCI mode with LBPC = 01, all
accesses to 60x bus SDRAM fails. Uboot failed in get_ram_size() routine.
The selection of localbus operation mode is done by SW9. Switch the jumper
back to localbus SDRAM mode, U-boot boots to the prompt and access to 60x
SDRAM is fine. Does anybody have similar experience? Any insight is
