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 * bug fixes patchset history ----------------- [v1] : https://lkml.org/lkml/2014/4/18/216 Ley Foon Tan (29): nios2: Assembly macros and definitions nios2: Kernel booting and initialization nios2:
