Every CPU has its own debug module and this module is used by JTAG debugging and coresight tracing. If without enabling it, it's easily to introduce lockup issue when we enable debugging features. This patch is to enable CPU debug module when power on CPU; this allows connecting to all cores through JTAG and used by kernel coresight driver.
