From: Stephen Warren <swar...@nvidia.com>
This hooks into the generic "file exists" support added in an earlier
patch, and provides an implementation for the sandbox test environment.
Signed-off-by: Stephen Warren <swar...@nvidia.com>
Acked-by: Simon Glass <s...@chromium.org>

v3:
* Remove "sb exists" command; it's part of "test" now.
* Invert return value of exists(), per change to previous patch.
v2: No change.
