[U-Boot] list files on tftp / large kernel-image

[Frank Wunderlich]

i've walked through code and it seems i've found it in cmd/strings.c

strings
	display strings
	<addr> [byte count]
	    - display strings at <addr> for at least [byte count] or first double NUL

does tftp add the "double NUL" if i do this:

tftp 0x80200000 filelist.txt
strings 0x80200000

or do i need to add ${filesize} to strings-command (if this is set via tftp)

regards Frank
