The\nQEMU virt machine models a generic system based on the Motorola 68040\nCPU and utilizes Goldfish virtual peripherals.\n\nCurrently, U-Boot's m68k architecture support focuses on ColdFire\nvariants. Expand this to include the classic M680x0 architecture,\nimplementing the necessary exception vectors, startup code, and a\nbootinfo parser compatible with the QEMU interface. A driver for the\nGoldfish TTY is also added to enable serial console output.\n\nThe implementation has been verified on QEMU targeting the M68040 CPU,\nconfirming successful hardware initialization and boot to the U-Boot\ncommand shell.\n\nKuan-Wei Chiu (3):\n serial: Add Goldfish TTY driver\n m68k: Add support for M68040 CPU\n board: Add QEMU m68k virt board support\n\n MAINTAINERS | 6 ++\n arch/m68k/Kconfig | 23 ++++++\n arch/m68k/Makefile | 1 +\n arch/m68k/config.mk | 10 ++-\n arch/m68k/cpu/m68040/Makefile | 6 ++\n arch/m68k/cpu/m68040/cpu.c | 77 ++++++++++++++++++\n arch/m68k/cpu/m68040/start.S | 83 +++++++++++++++++++\n arch/m68k/cpu/m68040/u-boot.lds | 47 +++++++++++\n arch/m68k/include/asm/bootinfo.h | 31 +++++++\n arch/m68k/lib/Makefile | 9 +--\n board/emulation/qemu-m68k/Kconfig | 12 +++\n board/emulation/qemu-m68k/MAINTAINERS | 10 +++\n board/emulation/qemu-m68k/Makefile | 5 ++\n board/emulation/qemu-m68k/qemu-m68k.c | 84 +++++++++++++++++++\n configs/qemu-m68k_defconfig | 17 ++++\n doc/board/emulation/qemu-m68k.rst | 38 +++++++++\n drivers/serial/Kconfig | 8 ++\n drivers/serial/Makefile | 1 +\n drivers/serial/serial_goldfish.c | 112 ++++++++++++++++++++++++++\n include/configs/qemu-m68k.h | 18 +++++\n include/goldfish_tty.h | 18 +++++\n 21 files changed, 608 insertions(+), 8 deletions(-)\n create mode 100644 arch/m68k/cpu/m68040/Makefile\n create mode 100644 arch/m68k/cpu/m68040/cpu.c\n create mode 100644 arch/m68k/cpu/m68040/start.S\n create mode 100644 arch/m68k/cpu/m68040/u-boot.lds\n create mode 100644 arch/m68k/include/asm/bootinfo.h\n create mode 100644 board/emulation/qemu-m68k/Kconfig\n create mode 100644 board/emulation/qemu-m68k/MAINTAINERS\n create mode 100644 board/emulation/qemu-m68k/Makefile\n create mode 100644 board/emulation/qemu-m68k/qemu-m68k.c\n create mode 100644 configs/qemu-m68k_defconfig\n create mode 100644 doc/board/emulation/qemu-m68k.rst\n create mode 100644 drivers/serial/serial_goldfish.c\n create mode 100644 include/configs/qemu-m68k.h\n create mode 100644 include/goldfish_tty.h"}
