OF_HOSTFILE is used on sandbox configs only. Although it's pretty unique and not causing any confusions, we are better of having simpler config options for the DTB. So let's replace that with the existing OF_BOARD. U-Boot would then have only three config options for the DTB origin. - OF_SEPARATE, build separately from U-Boot - OF_BOARD, board specific way of providing the DTB - OF_EMBED embedded in the u-boot binary(should not be used in production Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>
