Subject: cmd: nfsdown: add image file name as optional argument
X-Git-Tag: submit/tizen/20170808.230223~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9817f4a0e8bcf2c6d38814c0c203a210fc704b54;p=platform%2Fkernel%2Fu-boot.git

cmd: nfsdown: add image file name as optional argument

The nfsdown command takes too much time because it tries to get
all possible image files. Add image file name as optional argument.
With the optional argument, nfsdown command will get only the file
and it reduces time consumption for case of flashing one file.
