The sysinfo_get_str() implementation checks whether the sysinfo was even detected. In U-Boot proper, sysinfo_detect() is not called anywhere but on one specific board. Call sysinfo_detect() before sysinfo_get_str() to make sure the sysinfo is detected and sysinfo_get_str() returns valid value instead of -EPERM.
