[U-Boot] [patch 0/2] Several U-boot uImage building patches

[Remy Bohmer]

Here follows a series of 2 patches that provide some additional functionality
to building Linux kernel uImages for U-boot:
* Make it possible to base uImage on the non-compressed kernel 'Image' instead
  of 'zImage'.
* Add support for the new U-boot uImage file format, called FIT. This will allow
  a kernel to be build directly in this new format instead of the legacy format,
  IF the proper tools are available (dtc v1.2.0 and mkimage 1.3.3; dtc is
  checked by version-number, the proper mkimage is detected by cmd-line
  options, it must provide a '-f' option)

  If older, or improper tools are detected, then the Legacy style image is
  build after issuing a warning message.
