If we #define CONFIG_RW_B, the firmware image can have two RW components. This CL expands the "sysinfo" command so that we can see which image we're running from when RW_B is also a possibility. BUG=chrome-os-partner:50701 BRANCH=none TEST=make buildall; test RW update on Cr50 Using test/tpm_test/tpmtest.py, update the RW firmware and reboot several times to switch between RW_A and RW_B. Note that the "sysjump" command reports the correct image each time.
