The image_setup_libfdt() function optionally calls the LMB API to reserve the region of memory occupied by the FDT blob. This was earlier determined through the presence of the pointer to the lmb structure, which is no longer present. Pass a flag to the image_setup_libfdt() function to indicate if the region occupied by the FDT blob is to be marked as reserved by the LMB module.
