There is no need to invalidate the inactive RW image if it's already been done. Check the magic area of the header and if already 0s, then set *response_size and return VENDOR_RC_SUCCESS. BUG=chrome-os-partner:62588 BRANCH=none TEST=manual Update H1 FW on Eve. Using 'ver' command verify that it has valid A/B RW images. Log into chromeos and see console messages indicating that inactive image is being invalidated and via 'ver' command. Reboot via H1 console and see that this time the message vc_invalidate_inactive_rw: Inactive region already corrupted is displayed.
