Disk IO functions are used by both FS and USB Mass Storage. This patch refactors those from FS directory to a separate one. In addition existing, config options were modified to make stuff meaningful. Jira: ZEP-1276 Change-Id: Ia2a2e18f3dbbbdb964c3dc0427d8138ad86134cd Signed-off-by: Jithu Joseph <jithu.joseph@intel.com>
