Until we update the naming for our various images in the Makefiles, let's change the bootloader message slighty, so that instead of seeing two "RO" images: CR50 RO, 20151104_41733@78962 Valid image found at 0x00044000, jumping --- UART initialized after reboot --- [Reset cause: power-on] [Image: RO, cr50_v1.1.4008-957a842 2015-11-07 00:28:37 wfrichar@wintermute4.mtv. corp.google.com] [0.000897 Verifying RW image...] we see the bootloader, and then what we've been calling the RO image, and then the RW image: cr50 bootloader, 20151104_41733@78962 Valid image found at 0x00044000, jumping --- UART initialized after reboot --- [Reset cause: power-on] [Image: RO, cr50_v1.1.4008-957a842 2015-11-07 00:28:37 wfrichar@wintermute4.mtv. corp.google.com] [0.000897 Verifying RW image...] BUG=none BRANCH=none TEST=make buildall, try it No new functionality, just a different message on the console.
