Flavio Ceolin	5408f3102d	debug: x86: Add gdbstub for X86 It implements gdb remote protocol to talk with a host gdb during the debug session. The implementation is divided in three layers: 1 - The top layer that is responsible for the gdb remote protocol. 2 - An architecture specific layer responsible to write/read registers, set breakpoints, handle exceptions, ... 3 - A transport layer to be used to communicate with the host The communication with GDB in the host is synchronous and the systems stops execution waiting for instructions and return its execution after a "continue" or "step" command. The protocol has an exception that is when the host sends a packet to cause an interruption, usually triggered by a Ctrl-C. This implementation ignores this instruction though. This initial work supports only X86 using uart as backend. Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>	5 years ago

debug: x86: Add gdbstub for X86

It implements gdb remote protocol to talk with a host gdb during the
debug session. The implementation is divided in three layers:

1 - The top layer that is responsible for the gdb remote protocol.
2 - An architecture specific layer responsible to write/read registers,
    set breakpoints, handle exceptions, ...
3 - A transport layer to be used to communicate with the host

The communication with GDB in the host is synchronous and the systems
stops execution waiting for instructions and return its execution after
a "continue" or "step" command. The protocol has an exception that is
when the host sends a packet to cause an interruption, usually triggered
by a Ctrl-C. This implementation ignores this instruction though.

This initial work supports only X86 using uart as backend.
