Subject: [PATCH] bootm/fdt: Only process the fdt if an fdt address was
provided
Boards with CONFIG_OF_LIBFDT enabled are not able to boot old-style
kernels using the board info structure (instead of passing a device tree)
This change allows the old style booting to be used if the fdt argument
was not passed to 'bootm'.
