[PATCH 00/20] RISC-V: rework for PBL, VIRT and 64-Bit support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

  RISC-V: add 64-bit support
  RISC-V: add Qemu virt support
