This patch adds board support for the BeagleV-Ahead. It uses a custom kernel for the board's SoC. As the SoC has an outdated and currently not supported version of the RISC-V vector extension, the vector extension is disabled. The used OpenSBI version for this board support does not define the neccessary flags for GCC 12 to activate the zicsr and zifencei extensions. Therefore this board support uses GCC 13. The boot command for the custom uboot to boot the kernel could not easily be changed. It seemed that a default boot command was persisent and any change to it by normal means (e.g., uboot config parameters like CONFIG_BOOT_COMMAND) did not have any effect. Hence a patch for the custom u-boot is introduced for now, to insert the proper boot command. The custom kernel has CLOCK_ALLOW_WRITE_DEBUGFS enabled by default. Therefore, this boards supports features a patch, which disables this again, as this option can be dangerous, if activated. https://www.beagleboard.org/boards/beaglev-ahead Signed-off-by: Kilian Zinnecker <kilian.zinnecker@mail.de> --- DEVELOPERS | 2 + board/beaglev-ahead/genimage.cfg | 62 +++++++++++++++ board/beaglev-ahead/linux.fragment | 2 + ...01-Disable-CLOCK_ALLOW_WRITE_DEBUGFS.patch | 30 +++++++ .../0001-Overwrite-bootcmd-by-force.patch | 30 +++++++ board/beaglev-ahead/post-image.sh | 6 ++ board/beaglev-ahead/readme.txt | 78 +++++++++++++++++++ board/beaglev-ahead/uEnv.txt | 4 + board/beaglev-ahead/uboot.fragment | 2 + configs/beaglev_ahead_defconfig | 46 +++++++++++ 10 files changed, 262 insertions(+) create mode 100644 board/beaglev-ahead/genimage.cfg create mode 100644 board/beaglev-ahead/linux.fragment create mode 100644 board/beaglev-ahead/patches/linux/0001-Disable-CLOCK_ALLOW_WRITE_DEBUGFS.patch create mode 100644 board/beaglev-ahead/patches/uboot/0001-Overwrite-bootcmd-by-force.patch create mode 100755 board/beaglev-ahead/post-image.sh create mode 100644 board/beaglev-ahead/readme.txt create mode 100644 board/beaglev-ahead/uEnv.txt create mode 100644 board/beaglev-ahead/uboot.fragment create mode 100644 configs/beaglev_ahead_defconfig
