Changeset 8956:3c7003592b5f
---------------------------
Config: Add command line options for disk image and memory size
Added the options to Options.py for FS mode with backward compatibility. It is
good to provide an option to specify the disk image and the memory size from
command line since a lot of disk images are created to support different
benchmark suites as well as per user needs. Change in program also leads to
change in memory requirements. The memeory size option should be used while
using simgle memory. These options provide the interface to provide both disk
image and memory size from the command line and gives more flexibility.

Testing done to confirm backward compatibility
