19.33.1 Entry (ROM_ENTRYn)
The System ROM Table begins with "n" relative 32-bit addresses, one for each debug
component present in the device and terminating with an all-zero value signaling the end
of the table at the "n+1"-th value.
NOTE
See Chip Configuration chapter for the debug components these
registers point to.
It is hardwired to specific values used during the auto-discovery process by an external
debug agent.
