[Buildroot] [PATCH v4 0/9] Add RV64 NOMMU and Canaan K210 SoC support
From: Damien Le Moal <hidden>
Date: 2021-08-30 04:41:14
This series adds support for building 64-bits RISC-V NOMMU kernel bootable images for boards using the dual-core RISC-V 64-bits Cannan Kendryte K210 SoC. The first patch adds support for RV64 to the elf2flt package. Patch 2 changes the base name of the toolchain cross-compilation executables to avoid build errors. With these preparatory patches in place, patch 3 makes MMU build optional for RISC-V 64-bits. The following 5 patches add default build configuration files for various boards: MAIX-bit, MAIX-go, MAIX-dock (Dan Dock) and MAIXDUINO from Sipeed and the Canaan KD233 development board. Finally, patch 9 documents how to build and install images for these boards. Note about patch 1: Many comments have been made on the elf2flt pull request. The elf2flt support needs to be reworked but may take some time. Until this is rewrite is completed, if acceptable, please take this patch as a temporary support. Changes from v3: * Rebased on latest tree Changes from v2: * Reorder patches: former patch 1 is now patch 3. * Clearly state in the first 3 patch commit messages that the NOMMU support introduced is for RISC-V 64-bits only and does not affect RV32. * Modify patch 3 to allow NOMMU builds only for RV64 as opposed to both RV32 and RV64 before. * Add reference to upstream elf2flt pull request in patch 1. * Simplify the configurations for all boards, keeping default settings when a special value is not needed (e.g. gcc version). * Dropped busybox-tiny-initramfs.config configuration and replaced it with a busybox fragment configuration file updating the default busybox-minimal.config configuration (used now for all boards). * Changed common k210 rootfs overlay to replace the default /init script with a symbolic link pointing to the overlay provided /sbin/init script. Changes from v1: * Rebased on latest master * Simplified patch 3 as suggested by Baruch * Fixed typos in documentation (patch 9) * Added reviewed-by tags Christoph Hellwig (2): package/elf2flt: add RISC-V 64-bits support package/Makefile.in: Fix NOMMU RISC-V 64-bits toolchain base name Damien Le Moal (7): arch/config: Make RISC-V 64-bits MMU optional board: Add Sipeed MAIX-bit support board: Add Sipeed MAIX-Go support board: Add Sipeed MAIXDUINO support board: Add Sipeed MAIX-Dock support board: Add Canaan KD233 support board: Document Canaan K210 based boards support arch/Config.in | 1 - arch/Config.in.riscv | 2 + board/canaan/k210-common/README.md | 318 ++++++++++++++++++ board/canaan/k210-common/busybox-tiny.config | 243 +++++++++++++ board/canaan/k210-common/rootfs_overlay/init | 1 + .../k210-common/rootfs_overlay/sbin/init | 27 ++ board/canaan/kd233/README.md | 4 + board/canaan/kd233/linux-dtb.config | 2 + board/sipeed/maix-bit/README.md | 4 + board/sipeed/maix-bit/linux-dtb.config | 2 + board/sipeed/maix-dock/README.md | 4 + board/sipeed/maix-dock/linux-dtb.config | 2 + board/sipeed/maix-go/README.md | 4 + board/sipeed/maix-go/linux-dtb.config | 2 + board/sipeed/maixduino/README.md | 4 + board/sipeed/maixduino/linux-dtb.config | 2 + configs/canaan_kd233_defconfig | 15 + configs/canaan_kd233_sdcard_defconfig | 14 + configs/sipeed_maix_bit_defconfig | 15 + configs/sipeed_maix_bit_sdcard_defconfig | 14 + configs/sipeed_maix_dock_defconfig | 15 + configs/sipeed_maix_dock_sdcard_defconfig | 14 + configs/sipeed_maix_go_defconfig | 15 + configs/sipeed_maix_go_sdcard_defconfig | 14 + configs/sipeed_maixduino_defconfig | 15 + configs/sipeed_maixduino_sdcard_defconfig | 14 + package/Makefile.in | 5 +- ...04-elf2flt-add-riscv-64-bits-support.patch | 299 ++++++++++++++++ package/elf2flt/Config.in.host | 2 +- 29 files changed, 1069 insertions(+), 4 deletions(-) create mode 100644 board/canaan/k210-common/README.md create mode 100644 board/canaan/k210-common/busybox-tiny.config create mode 120000 board/canaan/k210-common/rootfs_overlay/init create mode 100755 board/canaan/k210-common/rootfs_overlay/sbin/init create mode 100644 board/canaan/kd233/README.md create mode 100644 board/canaan/kd233/linux-dtb.config create mode 100644 board/sipeed/maix-bit/README.md create mode 100644 board/sipeed/maix-bit/linux-dtb.config create mode 100644 board/sipeed/maix-dock/README.md create mode 100644 board/sipeed/maix-dock/linux-dtb.config create mode 100644 board/sipeed/maix-go/README.md create mode 100644 board/sipeed/maix-go/linux-dtb.config create mode 100644 board/sipeed/maixduino/README.md create mode 100644 board/sipeed/maixduino/linux-dtb.config create mode 100644 configs/canaan_kd233_defconfig create mode 100644 configs/canaan_kd233_sdcard_defconfig create mode 100644 configs/sipeed_maix_bit_defconfig create mode 100644 configs/sipeed_maix_bit_sdcard_defconfig create mode 100644 configs/sipeed_maix_dock_defconfig create mode 100644 configs/sipeed_maix_dock_sdcard_defconfig create mode 100644 configs/sipeed_maix_go_defconfig create mode 100644 configs/sipeed_maix_go_sdcard_defconfig create mode 100644 configs/sipeed_maixduino_defconfig create mode 100644 configs/sipeed_maixduino_sdcard_defconfig create mode 100644 package/elf2flt/0004-elf2flt-add-riscv-64-bits-support.patch -- 2.31.1 _______________________________________________ buildroot mailing list buildroot@busybox.net http://lists.busybox.net/mailman/listinfo/buildroot
