This is the 3rd version of patchset adds the Linux kernel port for Nios II processor from Altera. All of the feedback from v2 patchseries has been addressed. Thanks to all who provided feedback on the previous version. About Nios II Cores ------------------- Nios II is a 32-bit embedded-processor architecture designed specifically for the Altera family of FPGAs. More information is available at http://www.altera.com/devices/processor/nios2/ni2-index.html Instruction set and architecture overview documents can be found on the following page: http://www.altera.com/literature/lit-nio2.jsp Nios2 GCC port is in mainline and will be in the FSF 4.9 release. The patchset are based on v3.17-rc3 and can also be found in the following git tree: git://git.rocketboards.org/linux-socfpga-next.git nios2-upstream v3: * asm-generic: add generic futex for !CONFIG_SMP * dma: empty function for dma_cache_sync() * dma: rework for _for_device() and _for_cpu() * irq: Enable SPARSE_IRQ and remove NR_IRQS * irq: remove NO_IRQ * io: move __IO_OUT[IN]_LOOP to C file * io: add dummy implementation for in{b}{w}{l} and out{b}{w}{l} * io: drop ioremap_writethrough() and drop ioremap_writethrough() * signal: change to use set_current_blocked() * signal: add error handling in setup_rt_frame() * time: rework timer driver and use clockevent framework * time: port to use asm-generic delay.h * time: change __delay to use timer * Kconfig: add define ARCH_HAS_READ_CURRENT_TIME * change to use of_platform_populate() and default of_default_bus_match_table * remove module_arch_cleanup * add comment to module_alloc * remove gpio.h, pci.h and use generic pci.h * remove stat.h and statfs.h, use generic version. * remove CLOCK_TICK_RATE * update Makefile * clean up uapi Kbuild file * add install.sh * remove nommu comment from license header
