Pull irq updates from Thomas Gleixner: "The irq departement delivers: - a cleanup series to get rid of mindlessly copied code. - another bunch of new pointlessly different interrupt chip drivers. Adding homebrewn irq chips (and timers) to SoCs must provide a value add which is beyond the imagination of mere mortals. - the usual SoC irq controller updates, IOW my second cat herding project" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) irqchip: gic-v3: Implement CPU PM notifier irqchip: gic-v3: Refactor gic_enable_redist to support both enabling and disabling irqchip: renesas-intc-irqpin: Add minimal runtime PM support irqchip: renesas-intc-irqpin: Add helper variable dev = &pdev->dev irqchip: atmel-aic5: Add sama5d4 support irqchip: atmel-aic5: The sama5d3 has 48 IRQs Documentation: bcm7120-l2: Add Broadcom BCM7120-style L2 binding irqchip: bcm7120-l2: Add Broadcom BCM7120-style Level 2 interrupt controller irqchip: renesas-irqc: Add binding docs for new R-Car Gen2 SoCs irqchip: renesas-irqc: Add DT binding documentation irqchip: renesas-intc-irqpin: Document SoC-specific bindings openrisc: Get rid of handle_IRQ arm64: Get rid of handle_IRQ ARM: omap2: irq: Convert to handle_domain_irq ARM: imx: tzic: Convert to handle_domain_irq ARM: imx: avic: Convert to handle_domain_irq irqchip: or1k-pic: Convert to handle_domain_irq irqchip: atmel-aic5: Convert to handle_domain_irq irqchip: atmel-aic: Convert to handle_domain_irq irqchip: gic-v3: Convert to handle_domain_irq ... |

OpenRISC Linux ============== This is a port of Linux to the OpenRISC class of microprocessors; the initial target architecture, specifically, is the 32-bit OpenRISC 1000 family (or1k). For information about OpenRISC processors and ongoing development: website http://openrisc.net For more information about Linux on OpenRISC, please contact South Pole AB. email: info@southpole.se website: http://southpole.se http://southpoleconsulting.com --------------------------------------------------------------------- Build instructions for OpenRISC toolchain and Linux =================================================== In order to build and run Linux for OpenRISC, you'll need at least a basic toolchain and, perhaps, the architectural simulator. Steps to get these bits in place are outlined here. 1) The toolchain can be obtained from openrisc.net. Instructions for building a toolchain can be found at: http://openrisc.net/toolchain-build.html 2) or1ksim (optional) or1ksim is the architectural simulator which will allow you to actually run your OpenRISC Linux kernel if you don't have an OpenRISC processor at hand. git clone git://openrisc.net/jonas/or1ksim-svn cd or1ksim ./configure --prefix=$OPENRISC_PREFIX make make install 3) Linux kernel Build the kernel as usual make ARCH=openrisc defconfig make ARCH=openrisc 4) Run in architectural simulator Grab the or1ksim platform configuration file (from the or1ksim source) and together with your freshly built vmlinux, run your kernel with the following incantation: sim -f arch/openrisc/or1ksim.cfg vmlinux --------------------------------------------------------------------- Terminology =========== In the code, the following particles are used on symbols to limit the scope to more or less specific processor implementations: openrisc: the OpenRISC class of processors or1k: the OpenRISC 1000 family of processors or1200: the OpenRISC 1200 processor --------------------------------------------------------------------- History ======== 18. 11. 2003 Matjaz Breskvar (phoenix@bsemi.com) initial port of linux to OpenRISC/or32 architecture. all the core stuff is implemented and seams usable. 08. 12. 2003 Matjaz Breskvar (phoenix@bsemi.com) complete change of TLB miss handling. rewrite of exceptions handling. fully functional sash-3.6 in default initrd. a much improved version with changes all around. 10. 04. 2004 Matjaz Breskvar (phoenix@bsemi.com) alot of bugfixes all over. ethernet support, functional http and telnet servers. running many standard linux apps. 26. 06. 2004 Matjaz Breskvar (phoenix@bsemi.com) port to 2.6.x 30. 11. 2004 Matjaz Breskvar (phoenix@bsemi.com) lots of bugfixes and enhancments. added opencores framebuffer driver. 09. 10. 2010 Jonas Bonn (jonas@southpole.se) major rewrite to bring up to par with upstream Linux 2.6.36
