    15

    On the NIOS2 and Xtensa architectures, we do not have
    CONFIG_SYS_TEXT_BASE set. This is a strict migration of the current
    values into the defconfig and removing them from the headers.

    I did not attempt to add more default values in and for now will leave
    that to maintainers.

  • ddcca7305   ARM: qemu-arm: Add support for AArch64 ... Browse Code »

    This adds support for '-machine virt' on AArch64. This is rather simple:
    we just add TARGET_QEMU_ARM_xxBIT to select a few different Kconfig
    symbols, provide the ARMv8 memory map from the board file and add a new
    defconfig based on the 32-bit defconfig.

  • ad12dc184   cmd: Toggle the default value of CONFIG_CMD_IMLS ... Browse Code »

    Having this as a 'default y' is rather annoying because it doesn't
    actually compile unless other options are defined in the board header:

    ../cmd/bootm.c: In function 'do_imls_nor':
    ../cmd/bootm.c:330:7: error: 'CONFIG_SYS_MAX_FLASH_BANKS' undeclared (first use in this function); did you mean 'CONFIG_SYS_MAX_FLASH_SECT'?
    i < CONFIG_SYS_MAX_FLASH_BANKS; ++i, ++info) {

    Make it 'default n' so people who develop new boards that start from a
    blank defconfig have one less compilation failure to debug.

  • 32f118292   ARM: Add a new arch + board for QEMU's 'virt' machine ... Browse Code »

    This board builds an U-Boot binary that is bootable with QEMU's 'virt'
    machine on ARM. The minimal QEMU command line is:

    qemu-system-arm -machine virt,highmem=off -bios u-boot.bin

    (Note that the 'highmem=off' parameter to the 'virt' machine is required for
    PCI to work in U-Boot.) This command line enables the following:
    - u-boot.bin loaded and executing in the emulated flash at address 0x0
    - A generated device tree blob placed at the start of RAM
    - A freely configurable amount of RAM, described by the DTB
    - A PL011 serial port, discoverable via the DTB
    - An ARMv7 architected timer
    - PSCI for rebooting the system
    - A generic ECAM-based PCI host controller, discoverable via the DTB

    Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
    The following ones are supported by both U-Boot and Linux:

    - To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
    -drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0
    - To add an Intel E1000 network adapter, pass e.g.:
    -net nic,model=e1000 -net user
    - To add an EHCI-compliant USB host controller, pass e.g.:
    -device usb-ehci,id=ehci
    - To add a NVMe disk, pass e.g.:
    -drive if=none,file=disk.img,id=mydisk -device nvme,drive=mydisk,serial=foo
