Description

The bootrd_debug is knob to enable boot time ramdisk read debug messages - in the reader code for ufs, hsfs etc accessing boot_archive file system. Since the boot archive is accessed so early, there is no way to set it with kmdb (kmdb is read from the boot archive), the only reasonable way to set it is via boot property quite like it is done for prom_debug and few others.

To set the debug, it is enough to set bootrd_debug=true, the value itself is not important as we only check if the variable exists.
