    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 202a674bb   armv8: semihosting: add a command to load semihosted images ... Browse Code »

    Instead of sprinkling custom code and calls over the Vexpress64
    boardfile, create a command that loads images using semihosting
    just like we would load from flash memory of over the network,
    using a special command:

    smhload

    This will make it possible to remove some custom calls and
    code and make the boot easier.

  • 261d27605   arm: Add support for semihosting for armv8 fastmodel targets. ... Browse Code »

    The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
    images and u-boot, and does this for virtual platforms by using
    semihosting. This commit extends this idea by allowing u-boot to also
    use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
    for a bootwrapper and produces a more realistic boot sequence with
    virtual models.

    Though the semihosting code is quite generic, support for armv7 in
    fastmodel is less useful due to the wide range of available silicon
    and the lack of a free armv7 fastmodel, so this change contains an
    untested armv7 placeholder for the service trap opcode.

    Please refer to doc/README.semihosting for a more detailed description
    of semihosting and how it is used with the armv8 virtual platforms.
