43 * Setup the FDT early so that we're not loading files during bi_load.
44 * Any such loading is inherently broken since bi_load uses the space
45 * just after all currently loaded files for the data that will be
46 * passed to the kernel and newly loaded files will be positioned in
49 * We're glossing over errors here because LOADER_FDT_SUPPORT does not
50 * imply that we're on a platform where FDT is a requirement. If we
51 * fix this, then the error handling here should be fixed accordingly.
