  • c71b64f36   libfdt: Add helper function to create a trivial, empty tree ... Browse Code »

    The libfdt read/write functions are now usable enough that it's become a
    moderately common pattern to use them to build and manipulate a device
    tree from scratch. For example, we do so ourself in our rw_tree1 testcase,
    and qemu is starting to use this model when building device trees for some
    targets such as e500.

    However, the read/write functions require some sort of valid tree to begin
    with, so this necessitates either having a trivial canned dtb to begin with
    or, more commonly, creating an empty tree using the serial-write functions
    first.

    This patch adds a helper function which uses the serial-write functions to
    create a trivial, empty but complete and valid tree in a supplied buffer,
    ready for manipulation with the read/write functions.
