+ * boot_get_fdt_fit() - load a DTB from a FIT file (applying overlays)
+ *
+ * This deals with all aspects of loading an DTB from a FIT.
+ * The correct base image based on configuration will be selected, and
+ * then any overlays specified will be applied (as present in fit_uname_configp).
+ *
+ * @param images Boot images structure
+ * @param addr Address of FIT in memory
+ * @param fit_unamep On entry this is the requested image name
+ * (e.g. "kernel") or NULL to use the default. On exit
+ * points to the selected image name
+ * @param fit_uname_configp On entry this is the requested configuration
+ * name (e.g. "conf-1") or NULL to use the default. On
+ * exit points to the selected configuration name.
+ * @param arch Expected architecture (IH_ARCH_...)
+ * @param datap Returns address of loaded image
+ * @param lenp Returns length of loaded image
+ *
+ * @return node offset of base image, or -ve error code on error
