Because they aren't coupled. I can reasonable want 64-bit PCI accessible on a pure 32-bit system. If we want to do this we should introduce a pci_addr_t/pci_size_t. - k _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
