2014-01-24MIPS: Netlogic: Add MSI support for XLPJayachandran C11-37/+586
Add MSI chip and MSIX chip definitions. For MSI, we map the link interrupt to a MSI link IRQ which will do a second level of dispatch based on the MSI status register. The MSI chip definitions use the MSI enable register to enable and disable the MSI irqs. For MSI-X, we split the 32 available MSI-X vectors across the four PCIe links (8 each). These PIC interrupts generate an IRQ per link which uses a second level dispatch as well. The MSI-X chip definition uses the standard functions to enable and disable interrupts.

2014-01-24MIPS: malta: Incorporate PIIX4 ACPI I/O region in PCI controller resourcesDeng-Cheng Zhu1-3/+3
Boot log says: pci 0000:00:0a.3: no compatible bridge window for [io 0x1000-0x103f] pci 0000:00:0a.3: no compatible bridge window for [io 0x1100-0x110f] The io resource starting point on Malta was modified by c5de50dada (MIPS: Malta: Change start address to avoid conflicts.) to avoid conflicts with ACPI and SMB devices. In fact, that was not needed (and now causing southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus() that accepts resource list) and 7c090e5bfa (mips/PCI: convert to pci_scan_root_bus() for correct root bus resources) had already done the correct fix. This patch actually reverts the change made by c5de50dada. And with this fix, log says: pci 0000:00:0a.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI pci 0000:00:0a.3: quirk: [io 0x1100-0x110f] claimed by PIIX4 SMB These things may not be used but as part of platform resources are better off to be included.

The defaults are not always applicable and it makes it hard for the bootloader to override them. By removing it we give the bootloader full control over what command line parameters to pass. Without this change we will need to modify the built-in dtb to add bootloader cmd line parameters or do some work to append them after we unflatten the device tree. Sead3 is a development board, that's why we want to be able to change boot parameters on the fly from the bootloader.

2014-01-23MIPS: Malta: use generic 8250 early consolePaul Burton4-75/+33
This patch switches Malta from using the MIPS implementation of early printk with Malta's prom_putchar to using the generic 8250_early implementation. This offers a couple of advantages: - We duplicate less generic code. - The UART can be initialised rather than being reliant upon inheriting a valid setup from the bootloader. The Malta console_config function is extended to initialise the early console if no earlycon= kernel parameter is provided, inheriting the modetty0 bootloader environment if present and falling back to a default 38400n8r setup if not. This matches the behaviour used for the regular console= parameter.

2014-01-23MIPS: Malta: mux & enable SERIRQ interruptPaul Burton2-0/+18
This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ pin of the PIIX4 and to enable that interrupt. The kernel depends upon the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but previously would not configure it, instead relying upon the bootloader having done so. If that is not the case then the typical result is that the system appears to hang once it reaches userland as no output is displayed on the UART.

2014-01-22MIPS: Add support for interAptiv coresLeonid Yegoshin9-1/+12
The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit.

2014-01-22MIPS: Add support for FTLBsLeonid Yegoshin7-14/+155
The Fixed Page Size TLB (FTLB) is a set-associative dual entry TLB. Its purpose is to reduce the number of TLB misses by increasing the effective TLB size and keep the implementation complexity to minimum levels. A supported core can have both VTLB and FTLB.
