The cpu release command for r5 mode (lockstep/split) argument accepts only string. But the zynqmp tcminit command accepts string or number for r5 mode (lockstep/split or 0/1) argument. To fix the r5 mode argument, the common argument (lockstep/split or 0/1) is used across different u-boot commands. Use the strcmp() instead of strncmp() to make uniform the r5 mode (lockstep/split or 0/1) for the zynqmp tcminit and cpu release command.
