Mark Cave-Ayland a écrit :
> OpenBIOS prior to SVN r1225 had a horrible bug when accessing PCI
> configuration space for PPC Mac architectures - instead of writing the PCI
> configuration data value to the data register address, it would instead write
> it to the data register address plus the PCI configuration address.
>
> For this reason, the MemoryRegions for the PCI data register for
> grackle/uninorth were extremely large in order to accomodate the entire PCI
> configuration space being accessed during OpenBIOS PCI bus enumeration. Now
> that the OpenBIOS images have been updated, reduce the MemoryRegion sizes down
> to a single 32-bit register as intended.
