* Update the hardware access register definitions and functions to bring them in line with other Netlogic software. * Update the platform bus to use PCI even for on-chip devices. Add a dummy PCI driver to ignore on-chip devices which do not need driver. * Provide memory and IRQ resource allocation code for on-chip devices which cannot get it from PCI config. * add support for on-chip PCI and USB interfaces. * update conf files, enable pci and retain old MAXCPU until we can support >32 cpus.
