We just load them blindly:

+ "tftp ${loadaddr} ${bootfile}; " \
+ "tftp ${fdtaddr} dtbs/${fdtfile}; " \

(uname_r)
+ "tftp ${loadaddr} vmlinuz-${uname_r}; " \
+ "tftp ${fdtaddr} dtbs/${uname_r}/${fdtfile}; " \

I guess we could do: ${tftp_dir}

+ "tftp ${loadaddr} ${tftp_dir}/${bootfile}; " \
+ "tftp ${fdtaddr} ${tftp_dir}/dtbs/${fdtfile}; " \

(uname_r)
+ "tftp ${loadaddr} ${tftp_dir}/vmlinuz-${uname_r}; " \
+ "tftp ${fdtaddr} ${tftp_dir}/dtbs/${uname_r}/${fdtfile}; " \
