Hi All,
In cpu/ppc4xx/start.S, the CPC0_PCI register is _initialized_, rather than being simply _updated_. This clears bits that are set during bootstrap from a serial eeprom. E.g. for the PerWE/PCI_INT mux, CPC0_PCI[SPE] always gets cleared.
I'm proposing a simple change and would like some feedback ... it's not clear to me if this will cause problems for existing boards.
Comments welcome :-)
