There's no need to duplicate the linker section for each architecture.
Instead, move the section declaration to common-rom.ld.

The exported structures that were originally introduced for OpenOCD have
since then been reused for other debugger plugins, including PyOCD and
Segger J-Link.
Rename the Kconfig option and the implementation from openocd to debug
thread info, so that it reflects the fact that this is no longer
specifically tied to OpenOCD.

the implementation of spinlock validation uses two LSB bits in the
bottom of a pointer union to store a CPU index, which only has space
for 4 CPUS. the MP_NUM_CPUS should be <= 4.

This removes the z_ prefix those (functions, enums, etc.) that
are being used outside the coredump subsys. This aligns better
with the naming convention.

This adds some shell commands to the logging backend. Since
this is a simple backend, only get/clear errors are
implemented.

This adds two new APIs to the coredump subsystem to perform
query and command. These can be used to query coredump subsys
for information, and to perform commands such as finding
out if there is a stored coredump.

The coredump frontend (mostly) consists of wrappers of backend
functions so there is really no need to track errors at
the frontend level. Let the backends deal with their own errors
and this simplifies the code a bit.

Originally there was a null backend but it was removed before
code was merged. However, some leftover code still refers to
this null backend. So remove the leftovers.

GDB on host may ask the guest to read the a pointer contents even if
it is pointing to NULL. Send an error code when this occurs.

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.

This adds a very primitive coredump mechanism under subsys/debug
where during fatal error, register and memory content can be
dumped to coredump backend. One such backend utilizing log
module for output is included. Once the coredump log is converted
to a binary file, it can be used with the ELF output file as
inputs to an overly simplified implementation of a GDB server.
This GDB server can be attached via the target remote command of
GDB and will be serving register and memory content. This allows
using GDB to examine stack and memory where the fatal error
occurred.

In case of SMP (i.e. multiple execution units processing
the same list of tasks) we cannot use the same data structures for
getting data about active tasks as with just one processor (UP).
So until explicit support of SMP is added make sure we don't allow
to select both OPENOCD & SMP simultaneously.
Moreover starting from
commit a203d21962 ("kernel: remove legacy fields in _kernel")
this will lead to build-time error if MP_NUM_CPUS > 1.

This commit renames the Kconfig `FP_SHARING` symbol to `FPU_SHARING`,
since this symbol specifically refers to the hardware FPU sharing
support by means of FPU context preservation, and the "FP" prefix is
not fully descriptive of that; leaving room for ambiguity.
