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. This can also be pulled from Github: https://github.com/a3f/barebox/tree/multi-image-riscv-v3 v2 -> v3: - reworded some commit titles - added new header format for barebox images - added filetype detection for new barebox image format - fixed use of uninitialized sp in Erizo ENTRY_POINT (Antony) - Replaced assembly entry point of generic DT image with customized version of new header format macro - early exit relocation if runtime offset == 0 - remove note about TLSF error that's now fixed after Antony's bisection - replace 2 line assembly function in entry_ll.S with inline code v1 -> v2: - moved compressed dtb helpers into common header for both ARM and RISC-V to use - relocate_to_adr(fixed_base) can now be called multiple times in a row - removed some extra spaces (Antony) - as arch is DT only, bumped pr_debug to pr_err if dt is not found. no panic, because with debug_ll you might still be able to boot to shell for further debugging - rename Makefile.erizo to Makefile.riscv. Let's just build all board images out of the same Makefile now - HAS_ARCH_SJLJ selected for 64-bit as well - don't require compiler to support atomics or floating point on rv64 (Rouven) - added RISCV timer for SBI and rdcycle mode. This is used on tinyemu virt. rdcycle mode could be used on erizo as well if suitable timerbase chosen. - activate first console because Tinyemu only describes virtio mmio region for console and no stdout-path Cheers, Ahmad Fatoum (19): partitions: don't allocate dma capable memory images: make BOARD_ARM_GENERIC_DT available for other arches ARM: make ARM_USE_COMPRESSED_DTB available for other arches ARM: aarch64: omit unused label in assembly serial: virtio-console: depend on, but don't select VIRTIO RISC-V: <asm/unaligned.h>: 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 filetype: detect RISC-V images RISC-V: implement PBL image header 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 and CLINT timers 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 | 7 +- arch/arm/cpu/start.c | 20 +- arch/arm/include/asm/barebox-arm.h | 7 -
