Subject: sandbox: Add 'sb' command to access filesystem features
X-Git-Tag: v2013.04-rc1~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d304931f236db3af4f6a6f522b140f26e63e3a18;p=platform%2Fkernel%2Fu-boot.git

sandbox: Add 'sb' command to access filesystem features

The new 'sb' command is intended to deal with sandbox-specific features
that have no parallel in other archs. This commit adds two sub-commands
to list a directory and read a file from the host filesystem.
