Like adding the policy name to the commandline and configuring pinmux based on the selected policy. If this series is to be applied after Ahamad's bootm change series, then the block to change the commandline has to be moved up to roughly line 720 into the function bootm_boot_prep, where all the other bootm_data->provide_*** checks are, so that the previous context remains the same.
