This is the 2nd version of patchset adds the Linux kernel port for Nios II processor from Altera. All of the feedback from v1 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 v3.16-rc5 and can also be found in the following git tree: git://git.rocketboards.org/linux-socfpga-next.git nios2-upstream ----------------- v2: * move "Build infrastructure" to last patch * remove unused console.o from Makefile * sorted nios2/Kconfig * change outw/inw to writew/readw in arch/nios2/kernel/time.c * update PAGE_SIZE to (_AC(1, UL) << PAGE_SHIFT) * remove config GENERIC_FIND_NEXT_BIT * rename NO_IOPORT to NO_IOPORT_MAP * restructure and sort filename in Makefile * add NIOS2 prefix to all nios2 specific configs * add targets in Makefile * remove arch specific misaligned profs * add debug message when unhandled page fault * include cpuinfo.h to registers.h * use generic PTRACE_GETREGSET/PTRACE_SETREGSET * set IO_SPACE_LIMIT to 0 * remove ZONE_DMA * update sys_cacheflush() * remove sys_mmap() * remove signal domain translation * update 3c120_devboard.dts * remove hardcoded constants from soc_dev * merge nios2_device_probe to nios2_soc_device_init * add nios2 and timer dts bindings. * use get_signal() signal_setup_done() * remove virt_to_bus and bus_to_virt * update io.h * update nios2 documentation * add futex support
