Hi, we are using U-Boot on PPC405 and PPC440EPx CPU in systems that have a lot of PCIe switches and PCIe/PCI bridges. Even multiple cascaded switches and bridges :-) U-Boot has no problems with these architecture.
But of course nobody really knows if there are issue that you might run into. Matthias On Friday 14 August 2009 01:33, dbrazeau wrote: > > Hi.
