----------------------------------------------------------------
Changed in v6:
 - use $() instead of ${} for make variables to be consistent with the
   Buildroot coding style.

Changed in v5:
 - Added Arnout's Acked-by tag.

Changed in v4:
 - more verbose help text for config options;
 - remove unneeded ifeq around the definition for UBOOT_BIN_IFT;
 - produce an error message if the user-specified cfg file does not exist;
 - use http URL, for helping people whose firewalls block git;
 - do not skip installation if the files are already installed.

New in v3:
 - update to the user-visible host packages policy discussed in
   mailing-list (Config.in.host etc) and listed in the Host Tools menu
 - update to current GENTARGETS infrastructure
 - bump to the latest git snapshot, which fixes compilation with host gcc 4.6

New in v2:
 - xxx_SOURCE is useless with the git download method, remove it;
 - OMAP_U_BOOT_UTILS_TARGETS is used only once, hardcoded it.
