This patch adds a userspace tool to access Linux kernel AML debugger
interface.
Tow modes are supported by this tool:
1. Interactive: Users are able to launch a debugging shell to talk with
in-kernel AML debugger.
Note that it's user duty to ensure kernel runtime integrity by using
this debugging tool:
A. Some control methods evaluated by the users may result in kernel
panics if those control methods shouldn't be evaluated by the OSPMs
according to the current BIOS/OS configurations.
B. Currently if a single stepping evaluation couldn't run to an end,
then the synchronization primitives acquired by the evaluation may
block normal OSPM control method evaluations.
2. Batch: Users are able to execute debugger commands in a script.
Note that in addition to the above duties, it's user duty to ensure
script runtime integrity by using this debugging tool in this mode:
C. Currently only those commands that are not used for single stepping
are suitable to be used in this mode.
D. If the execution of the command may cause a failure that could result
in an endless kernel execution, the execution of the script may also
get blocked.
To exit the utility, currently "exit/quit" commands are recommended, but
ctrl-C" can also be used.
