In some cases it is useful to use the C preprocessor to control the
content of a devicetree file. A specific use case is in testing,
where different combinations of node properties must be checked.
Provide a mechanism to allow arbitrary preprocessor flags to be passed
through CMake to affect the devicetree content.

Memory mapping, for now, will be a private kernel API
and is not intended to be application-facing at this time.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
We no longer plan to support a split address space with
the kernel in high memory and per-process address spaces.
Because of this, we can simplify some things. System RAM
is now always identity mapped at boot.
We no longer require any virtual-to-physical translation
for page tables, and can remove the dual-mapping logic
from the page table generation script since we won't need
to transition the instruction point off of physical
addresses.
CONFIG_KERNEL_VM_BASE and CONFIG_KERNEL_VM_LIMIT
have been removed. The kernel's address space always
starts at CONFIG_SRAM_BASE_ADDRESS, of a fixed size
specified by CONFIG_KERNEL_VM_SIZE.
Driver MMIOs and other uses of k_mem_map() are still
virtually mapped, and the later introduction of demand
paging will result in only a subset of system RAM being
a fixed identity mapping instead of all of it.

Flash memory can be write but there is no way to check flash integrity.
Add flash_img_check method that verify flash integrity. This is useful
to avoid firmware reboot and test. Another use is ensure that firmware
upgrade routines from internet server to flash slot are performing
properly. This uses flash_area_check_int_sha256 method to check a
SHA-256 hash. On sucess match, zero is returned, otherwise a negative
errno value.

When lazy loading of CCCs are enabled there is no settings set handler
register for the 'bt/ccc' key, this means that the settings set handler
for 'bt' key is called instead. This handler does not know what to do
for the 'ccc' subkey, and returns -ENOENT for the entry.
This results in an error message logged by the settings subsystem.
"E: set-value failure. key: bt/ccc/f8c39e2f98210 error(-2)"

This new option allows to include `sockets_tls.c` into the build when
socket offloading is enabled.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Given that the offloaded poll handling differs from the poll handling of
native sockets (entire poll function call is offloaded), some
adjustements were needed to make TLS socket work with offloaded poll
calls.
To achieve this, in case socket offloading is used, instead of jumping
directly to the offloaded poll call, a TLS wrapper for the offloaded
poll will be called. This wrapper will do additional checks at the
mbedtls level, to verify that the event is only notified to the caller
when the application data is available (i. e. not to report events
during handshake or when partial data is received, not ready to
decrypt).

Separate TLS sockets implementation from net_context layer. Instead of
calling net_context functions directly, create an underlying TCP/UDP
socket, and call socket functions on it instead. This results in a
simpler design, where we don't need to duplicate specific parts of code
from the native socket implementation. Additionally, this allows to use
a different TCP/UDP stack underneath (i. e. when sockets offloading is
used).

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.

The default priority for I2C controller initialization is POST_KERNEL
60 (SPI 70), while the default priority for device configuration is
POST_KERNEL 50. Thus the EEPROM is being initialized before its
controller. While for this driver that wouldn't be an issue recent
changes mean the device lookup returns NULL before the device is
initialized.
Change the AT2X priority to 75 so it falls between the I2C and SPI
drivers and the default ethernet priority (80), since some ethernet
controllers may store the MAC address in EEPROM.
