Can you please push your RISC-V working branch to github (or other public git repo), so I can test it too? At the moment I have at least two out-of tree RISC-V branches that which I want to rebase on latest barebox with your patches: * https://github.com/frantony/barebox/tree/20200222.riscv-sifive contains hacky 64-bit support and add Sifive U500 qemu support. * https://github.com/litex-hub/barebox/tree/20200727.litex-vexriscv-linux contains litex SoC with RISC-V 32-bit CPU core support. It can run linux on Arty, please see https://github.com/enjoy-digital/litex/issues/413#issuecomment-609047340 It seems, that ethernet driver needs update: https://github.com/litex-hub/barebox/issues/1 I suppose that you can add 'bootm: add RISC-V image type' patch to your series (I'll send you the patch in a few minutes). The patch used in the litex series. > With these changes applied, barebox can now generate images that can > be booted on qemu/tinyemu virt32 and virt64 machines. > > The boards have clocksource, virtio, cfi-flash, reboot and poweroff > support. > > Cheers, > Ahmad Fatoum (18): > partitions: don't allocate dma capable memory > images: make BOARD_ARM_GENERIC_DT available for other arches > ARM: rename CONFIG_ARM_USE_COMPRESSED_DTB to CONFIG_USE_COMPRESSED_DTB > ARM: aarch64: ommit unused label in assembly > serial: virtio-console: depend on, but don't select VIRTIO > filetype: detect RISC-V Linux kernel image > asm: unaligned: don't do unaligned accesses > RISC-V: debug_ll: ns16550: align C access size with assembly's > RISC-V: drop duplicate or unneeded cflags > RISC-V: add cacheless HAS_DMA support > RISC-V: erizo: move to arch/riscv/boards/erizo > RISC-V: import Linux' optimized string functions > RISC-V: implement PBL and relocation support > RISC-V: erizo: migrate to PBL > RISC-V: support symbol names in barebox image > RISC-V: add generic DT image > clocksource: add driver for RISC-V CLINT timer > power: reset: add drivers for generic syscon reset and poweroff > > Rouven Czerwinski (2): > RISC-V: add 64-bit support > RISC-V: add Qemu virt support > > Documentation/boards/riscv.rst | 72 ++++++- > Makefile | 1 + > arch/arm/Kconfig | 9 +- > arch/arm/cpu/start.c | 2 +- > arch/arm/lib64/runtime-offset.S | 2 +- > arch/arm/mach-at91/Kconfig | 2 +- > arch/arm/mach-imx/Kconfig | 26 +-- > arch/arm/mach-omap/Kconfig | 2 +- > arch/riscv/Kconfig | 66 +++++-- > arch/riscv/Makefile | 34 ++-- > arch/riscv/boards/Makefile | 2 + > arch/riscv/boards/erizo/Makefile | 3 + > arch/riscv/boards/erizo/lowlevel.c | 18 ++ > arch/riscv/boot/Makefile | 5 +- > arch/riscv/boot/board-dt-2nd-entry.S | 26 +++ > arch/riscv/boot/board-dt-2nd.c | 29 +++ > arch/riscv/boot/dtb.c | 25 --- > arch/riscv/boot/entry.c | 33 ++++ > arch/riscv/boot/entry.h | 15 ++ > arch/riscv/boot/entry_ll.S | 15 ++ > arch/riscv/boot/main_entry.c | 35 ---- > arch/riscv/boot/start.S | 68 ------- > arch/riscv/boot/start.c | 197 +++++++++++++++++++ > arch/riscv/boot/uncompress.c | 74 +++++++ > arch/riscv/configs/erizo_generic_defconfig | 5 -
