Hi, I'm the one who originally wrote that config file. If you don't need anything else from those scripts, I'd just use the mainline run scripts like Andreas said and copy the appropriate config values like O3_ARM_v7a.
Since those scripts were written the branch predictor structure was re-organized and gem5 added clock domains. It's a bit dated now.
