This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().
The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.
Limitations:
+ Right now the SDK lacks an x86_64 toolchain. The build will fall
back to a host toolchain if it finds no cross compiler defined,
which is tested to work on gcc 8.2.1 right now.
+ No x87/SSE/AVX usage is allowed. This is a stronger limitation than
other architectures where the instructions work from one thread even
if the context switch code doesn't support it. We are passing
-no-sse to prevent gcc from automatically generating SSE
instructions for non-floating-point purposes, which has the side
effect of changing the ABI. Future work to handle the FPU registers
will need to be combined with an "application" ABI distinct from the
kernel one (or just to require USERSPACE).
+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
of all memory. No MMU/USERSPACE support yet.
+ We are building with -mno-red-zone for stack size reasons, but this
is a valuable optimization. Enabling it requires automatic stack
switching, which requires a TSS, which means it has to happen after
MMU support.
+ The OS runs in 64 bit mode, but for compatibility reasons is
compiled to the 32 bit "X32" ABI. So while the full 64 bit
registers and instruction set are available, C pointers are 32 bits
long and Zephyr is constrained to run in the bottom 4G of memory.

All series STM32 have mostly the same GPIO architecture
and can share the same code for GPIO manipulation.
Functions of the external interrupt line control are also the same.
This patch extracts common code from them and put them into the 'common'
folder.
Functions of control GPIO of these series scattered in
soc/arm/st_stm32/stm32xx/ folders contain these functions:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(), stm32_gpio_set(),
stm32_gpio_get, stm32_gpio_enable_int().
This patch merges them into the gpio_stm32.c file.

Adds support for the device configuration data (DCD), which provides a
sequence of commands to the imx rt boot ROM to initialize components
such as an SDRAM.
It is now possible to use the external SDRAM instead of the internal
DTCM on the mimxrt1020_evk, mimxrt1050_evk, and mimxrt1060_evk. Note,
however, that the default board configurations still link data into
internal DTCM, therefore you must use a device tree overlay to override
"zephyr,sram = &sdram0"

Adds support for the boot data, image vector table, and FlexSPI NOR
config structures used by the imx rt boot ROM to boot an application
from an external xip flash device.
It is now possible to build and flash a bootable zephyr image to the
external xip flash on the mimxrt1020_evk, mimxrt1050_evk, and
mimxrt1060_evk boards via the 'ninja flash' build target and jlink
runner. Note, however, that the default board configurations still link
code into internal ITCM, therefore you must set CONFIG_CODE_HYPERFLASH=y
or CONFIG_CODE_QSPI=y explicitly to override the default. You must also
set CONFIG_NXP_IMX_RT_BOOT_HEADER=y to build the boot header into the
image.

location on APB bus. E.g. DT_SILABS_GECKO_USART_40010000_LABEL becomes
DT_SILABS_GECKO_USART_USART_0_LABEL. Thus it is possible to remove

Updates the MCUXpresso SDK to version 2.5.0 for applicable SoCs.
Wireless (KW*) and legacy (KL25) SoCs were not included in this
MCUXpresso SDK release and are therefore not updated here.
New in this release is SoC-level and board-level support for external
xip flash in the i.MX RT family.
For RT1050, we are now using the MCUXpresso SDK for the EVKB version of
the board, which correponds to an upgrade from A0 to A1 silicon.
However, we don't yet have Kconfigs in place to support A1 silicon part
numbers, and therefore add a simple cmake hack to convert A0 part
numbers to A1 part numbers.
The SDK flash driver interface also changed slightly in this release,
and thus the zephyr flash shim driver is updated accordingly.

Make the following nRF peripheral drivers:
- ADC
- GPIO
- I2C
- SPI
- UART
- USB_DEVICE
enabled by default so that users do not need to explicitly enable them
in their applications after choosing an nRF SoC as the build target.
Kconfig options enabling these drivers depend on both a given hardware
feature (e.g. I2C) and an nRF family SoC selected, so effectively they
will be automatically enabled only when it is adequate (and in most
cases these drivers are the only option for a given hardware feature
on nRF SoCs).
