| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XLP USB controller appears as a device on the internal SoC PCIe bus, the block has 2 EHCI blocks and 4 OHCI blocks. Change are to: * Add files netlogic/xlp/usb-init.c and asm/netlogic/xlp-hal/usb.h to initialize the USB controller and define PCI fixups. The PCI fixups are to setup interrupts and DMA mask. * Update include/asm/xlp-hal/{iomap.h,pic.h,xlp.h} to add interrupt mapping for EHCI/OHCI interrupts.

* MIPS: Netlogic: Mark Netlogic chips as SMT capableHillf Danton2011-12-071-4/+7
| | | | | | | | | | | | | | | | | | | Netlogic XLR chip has multiple cores. Each core includes four integrated hardware threads, and they share L1 data and instruction caches. If the chip is marked to be SMT capable, scheduler then could do more, say, idle load balancing. Changes are now confined only to the code of XLR, and hardware is probed to get core ID for correct setup.

* MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C2011-12-0710-222/+207
| | | | | | | | | | | | | | | | | | Create a common NMI and reset handler in smpboot.S and use this for both XLR and XLP. In the earlier code, the woken up CPUs would busy wait until released, switch this to wakeup by NMI. The initial wakeup code or XLR and XLP are differ since they are started from different bootloaders (XLP from u-boot and XLR from netlogic bootloader). But in both platforms the woken up CPUs wait and are released by sending an NMI. Add support for starting XLR and XLP in 1/2/4 threads per core.
