  • 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.

  • DEVDISRn registers provides a mechanism for gating clocks of IP blocks
    that are not used. Here we implement hwconfig option to allow users
    to disable unused peripherals on the board.

    For ex. If eSDHC/qDMA/eDMA are unused and with disabled status in dts,
    User can enable CONFIG_FSL_DEVICE_DISABLE and set "devdis:esdhc,qdma,edma"
    in hwconfig, thus ESDHC controller & eDMA/qDMA will be clock gated to
    save more power.
