Currently mx7d can boot the 2 CPUs if you use PSCI in the bootloader. Give mainline U-Boot a try and it will boot the 2 CPUs via PSCI. There was an attempt to add gpcv2 support at: https://patchwork.kernel.org/patch/6919831/ , and Shawn suggested to go to the PSCI approach. PSCI for mx7 is still missing suspend support though.
