"cramfsload uImage_1" succeeds even though the actual file is named "uImage".
Fix file name comparison when one name is the prefix of the other.
Signed-off-by: Holger Brunck holger.brunck@keymile.com cc: Wolfgang Denk wd@denx.de cc: Albert ARIBAUD albert.u.boot@aribaud.net --- If we have the following entry in cramfs: => cramfsls -rw-r--r-- 1922689 uImage
cramfsload would also succeed if we try to do: => cramfsload uImage_1 CRAMFS load complete: 1922689 bytes loaded to 0x100000
The old code succeeds if the begin of the filename we search matches with a filename stored in cramfs. But the searched file may have additional characters and is therfore not the file we are looking for.
