* MIPS: Netlogic: Support for XLR/XLS Fast Message NetworkGanesan Ramalingam2012-11-09
| | | | | | | | | | | | | | | | | | | | On XLR/XLS, the cpu cores communicate with fast on-chip devices (e.g. network accelerator, security engine etc.) using the Fast Messaging Network(FMN). The FMN queues and credits needs to be configured and intialized before it can be used. The co-processor 2 on XLR/XLS CPU cores has registers for FMN access, and the XLR/XLS has custom instructions for sending and loading messages. The FMN can deliver also per-cpu interrupts when messages are available at the CPU. This patch adds FMN initialization, adds interrupt setup and handling, and also provides support for sending and receiving FMN messages.

* MIPS: Netlogic: PIC IRQ handling update for multi-chipJayachandran C2012-11-09
| | | | | | | | | | | | Create struct nlm_pic_irq for interrupts handled by the PIC. This simplifies IRQ handling for multi-SoC as well as the single SoC cases. Also split the setup of percpu and PIC interrupts so that we can configure the PIC interrupts for every node.

* MIPS: Netlogic: Support for multi-chip configurationJayachandran C2012-11-09
| | | | | | | | | | | | Upto 4 Netlogic XLP SoCs can be connected over ICI links to form a coherent multi-node system. Each SoC has its own set of on-chip devices including PIC. To support this, add a per SoC stucture and use it for the PIC and SYS block addresses instead of using global variables.

* MIPS: Netlogic: USB support for XLPGanesan Ramalingam2012-07-24
| | | | | | | | | | | | | | | | | 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: XLP PCIe controller support.Ganesan Ramalingam2012-07-24
| | | | | | | | | | | | | | | | | Adds support for the XLP on-chip PCIe controller. On XLP, the on-chip devices(including the 4 PCIe links) appear in the PCIe configuration space of the XLP as PCI devices. The changes are to initialize and register the PCIe controller, enable hardware byte swap in the PCIe IO and MEM space, and to enable PCIe interrupts.

* MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C2011-12-07
| | | | | | | | | | | | | | | | | | 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.
