Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the third of the KV family has the following features: - 32/64 bits execution mode - 6-issue VLIW architecture - 64 x 64bits general purpose registers - SIMD instructions - little-endian This port is a 64 bits one and allows to boot up to a barebox prompt on a k200 board. kv3 support for clocksource and watchdog is also part of this port. In order to build a usable toolchain, build scripts are provided at the following address: https://github.com/kalray/build-scripts. Kalray uses FOSS which is available at https://github.com/kalray Changes v1 -> v2 - Rename k1c -> kvx after marketing decision - Remove ELF_CLASS definition (waiting for official ELF id) - Include stack in linker script - Dynamically determine malloc_base and malloc_size using device tree - Get device tree from bootloader if magic number is present - Remove dead code from watchdog - Add patch for reset source and enable CMD_RESET - Rebase on master branch Clement Leger (6): kvx: Initial Kalray Coolidge (kv3) architecture support kvx: Add processor definitions kvx: Add support for device tree kvx: Implement reset source and reset clocksource: kvx: Add kvx clocksource support watchdog: kvx: Add kvx watchdog support arch/kvx/Kconfig | 55 + arch/kvx/Makefile | 37 + arch/kvx/configs/generic_defconfig | 14 + arch/kvx/cpu/Makefile | 7 + arch/kvx/cpu/barebox.lds.S | 95 + arch/kvx/cpu/cpu.c | 32 + arch/kvx/cpu/exception.S | 24 + arch/kvx/cpu/reset.c | 67 + arch/kvx/cpu/start.S | 184 + arch/kvx/dts/Makefile | 13 + arch/kvx/dts/k200.dts | 110 + arch/kvx/include/asm/barrier.h | 18 + arch/kvx/include/asm/bitops.h | 27 + arch/kvx/include/asm/bitsperlong.h | 12 + arch/kvx/include/asm/byteorder.h | 12 + arch/kvx/include/asm/common.h | 27 + arch/kvx/include/asm/elf.h | 18 + arch/kvx/include/asm/ftu.h | 24 + arch/kvx/include/asm/io.h | 14 + arch/kvx/include/asm/linkage.h | 10 + arch/kvx/include/asm/posix_types.h | 12 + arch/kvx/include/asm/privilege.h | 192 ++ arch/kvx/include/asm/sections.h | 12 + arch/kvx/include/asm/sfr.h | 47 + arch/kvx/include/asm/sfr_defs.h | 5029 ++++++++++++++++++++++++++++ arch/kvx/include/asm/string.h | 14 + arch/kvx/include/asm/swab.h | 14 + arch/kvx/include/asm/sys_arch.h | 46 + arch/kvx/include/asm/types.h | 14 + arch/kvx/include/asm/unaligned.h | 17 + arch/kvx/lib/Makefile | 6 + arch/kvx/lib/asm-offsets.c | 11 + arch/kvx/lib/board.c | 119 + arch/kvx/lib/cpuinfo.c | 20 + arch/kvx/lib/dtb.c | 29 + arch/kvx/lib/poweroff.c | 43 + drivers/clocksource/Kconfig | 4 + drivers/clocksource/Makefile | 1 + drivers/clocksource/kvx_timer.c | 59 + drivers/of/Kconfig | 2 +- drivers/watchdog/Kconfig | 6 + drivers/watchdog/Makefile | 1 + drivers/watchdog/kvx_wdt.c | 94 + 43 files changed, 6591 insertions(+), 1 deletion(-) create mode 100644 arch/kvx/Kconfig create mode 100644 arch/kvx/Makefile create mode 100644 arch/kvx/configs/generic_defconfig create mode 100644 arch/kvx/cpu/Makefile create mode 100644 arch/kvx/cpu/barebox.lds.S create mode 100644 arch/kvx/cpu/cpu.c create mode 100644 arch/kvx/cpu/exception.S create mode 100644 arch/kvx/cpu/reset.c create mode 100644 arch/kvx/cpu/start.S create mode 100644 arch/kvx/dts/Makefile create mode 100644 arch/kvx/dts/k200.dts create mode 100644 arch/kvx/include/asm/barrier.h create mode 100644 arch/kvx/include/asm/bitops.h create mode 100644 arch/kvx/include/asm/bitsperlong.h create mode 100644 arch/kvx/include/asm/byteorder.h create mode 100644 arch/kvx/include/asm/common.h create mode 100644 arch/kvx/include/asm/elf.h create mode 100644 arch/kvx/include/asm/ftu.h create mode 100644 arch/kvx/include/asm/io.h create mode 100644 arch/kvx/include/asm/linkage.h create mode 100644 arch/kvx/include/asm/posix_types.h create mode 100644 arch/kvx/include/asm/privilege.h create mode 100644 arch/kvx/include/asm/sections.h create mode 100644 arch/kvx/include/asm/sfr.h create mode 100644 arch/kvx/include/asm/sfr_defs.h create mode 100644 arch/kvx/include/asm/string.h create mode 100644 arch/kvx/include/asm/swab.h create mode 100644 arch/kvx/include/asm/sys_arch.h create mode 100644 arch/kvx/include/asm/types.h create mode 100644 arch/kvx/include/asm/unaligned.h create mode 100644 arch/kvx/lib/Makefile create mode 100644 arch/kvx/lib/asm-offsets.c create mode 100644 arch/kvx/lib/board.c create mode 100644 arch/kvx/lib/cpuinfo.c create mode 100644 arch/kvx/lib/dtb.c create mode 100644 arch/kvx/lib/poweroff.c create mode 100644 drivers/clocksource/kvx_timer.c create mode 100644 drivers/watchdog/kvx_wdt.c -- 2.17.1 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
