The CL adds the --config and --vblock option to kernel_utility. --config <file> uses the file to populate the configuration portion within a signed vbootimage Currently, the configuration file is assumed to only contain command line options to be passed to the kernel. In the future, we might want to change it so that it contains information about the kernel load address, entry points, etc. (refer to rspangler@ drive map design doc) --vblock makes the tool only output the verification header instead of a one monolithic signed kernel image containing the verification information (with config information contained within it) followed by the actual kernel image Review URL: http://codereview.chromium.org/1752013
