+ help
+ The trace router uses the Linux tty line discipline framework to

+ drivers/misc/pti.c defines the majority of this MIPI solution.

+ If you want early console (udbg) output through a byte channel,
+ specify the handle of the byte channel to use.
+
+ For this to work, the byte channel driver must be compiled
+ in-kernel, not as a module.
+
+ Note that only one early console driver can be enabled, so don't
+ enable any others if you enable this one.
+
+ If the number you specify is not a valid byte channel handle, then
+ there simply will be no early console output. This is true also
+ if you don't boot under a hypervisor at all.
