This should match Linux now.\n - Added patch to fix sys reset which is broken by the above\n - Hacks to virtio-mmio are gone because they aren't needed\n anymore, just one minor endian fix now.\n - Removed RFC because it looks good to me*.\n\n\n* I wouldn't trust me. :)\n\nDaniel Palmer (6):\n sysreset: qemu virt: Use __raw_writel()\n m68k: Fix writew(), writel(), readw(), readl() endianness for classic\n m68k\n virtio: mmio: Allow instantiation via platform data\n virtio: cmd: Depend on VIRTIO_BLK\n virtio: blk: Fix converting the vendor id to a string\n board: qemu: m68k: Create virtio mmio instances\n\n arch/m68k/Kconfig | 14 ++++---\n arch/m68k/include/asm/io.h | 31 +++++++++------\n board/emulation/qemu-m68k/qemu-m68k.c | 45 ++++++++++++++++++++++\n cmd/Kconfig | 4 +-\n drivers/sysreset/sysreset_qemu_virt_ctrl.c | 2 +-\n drivers/virtio/virtio_blk.c | 11 ++----\n drivers/virtio/virtio_mmio.c | 27 ++++++++-----\n include/virtio.h | 3 ++\n include/virtio_mmio.h | 12 ++++++\n 9 files changed, 113 insertions(+), 36 deletions(-)\n create mode 100644 include/virtio_mmio.h" }
