When QEMU is running in icount mode, the behaviour regarding
the CPU being in sleep mode is configurable, with the default
value being set to 'off'. In this case, instruction counting
continues even when the CPU is sleeping or no target time is
set in the system timer. If the sleep parameter is set to
'on', instruction counting stops if the CPU is sleeping, and
the instruction count will fast-forward directly to the next
target time once it is being set.
In the Xilinx derivative of QEMU (which simulates ZynqMP and
Zynq-7000 SoCs), the default configuration causes QEMU to no
longer accept control commands via the console or remotely
whenever Zephyr enters and remains in idle mode.
Therefore, this commit makes the value of the sleep para-
meter of the icount functionality configurable, with the
default value remaining 'off'. The value can be changed at
board level alongside with the specification of the icount
shift value.

This commit splits the 'locore' and 'main' memory regions into
separate executable images and specifies the 'locore' as the boot
kernel, in order to prevent the QEMU direct multiboot kernel loader
from overwriting the BIOS and option ROM areas located in between
the two memory regions.
The Zephyr x86-64 kernel image consists of two discontiguous load
memory regions: 'locore' at 0x8000 and 'main' at 0x100000, but the
QEMU treats these as single contiguous memory region starting at
0x8000 and ending at (0x100000 + MAIN_IMAGE_SIZE - 1).
This results in the direct multiboot kernel loader overwriting the
BIOS and option ROM areas as part of the kernel loading process, and
causes any writable system regions to be corrupted (e.g. KVMVAPIC ROM).
By splitting the two discontiguous memory regions into separate images
and specifying only the boot image (i.e. 'locore') as the '-kernel',
it is possible to work around the QEMU direct kernel loading design
limitation.
This workaround is required to support the QEMU v4.2.0 and above.
For more details, refer to the issue zephyrproject-rtos/sdk-ng#168.

The current QEMU console configuration directly connects the console
serial port to the backend using '-serial' option.
This is less than ideal because only single console instance can be
connected to a backend and aggregation of multiple console outputs is
not possible (e.g. multiple console serial ports and semihosting
console to single console backend).
In order to solve this problem, single multiplexed chardev console
backend is declared and all consoles are connected to it.

This was a very early test and got bitrotten inside a esp32-only
whitelist. Make it run generically.
SMP must be forced off by the test (it's commonly a platform default).
Add a build-time failure when the configuration is single-CPU, for
clarity.
Filter the test likewise so it runs on all supported systems.
Also, the key argument to the CPU startup function is vestigial and
the test was being too strict by requiring it to be non-zero.
Finally, the qemu command line needs to predicate the "-smp" argument
on CONFIG_MP_NUM_CPUS and not just CONFIG_SMP so we have an extra CPU
to test against.

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.

I don't know why we have been passing "-serial none" to qemu but it
does not seem to be doing anything useful. So I propose we remove it.
According to the qemu documenation it should be disabling all serial
ports;
"-serial dev
Redirect the virtual serial port to host character device dev. The
default device is vc in graphical mode and stdio in non graphical
mode.
This option can be used several times to simulate up to 4 serial
ports.
Use -serial none to disable all serial ports."
But when we use "-serial none", we always combine it with "-serial
pipe", or "-serial unix", to redirect the serial port, so clearly it
is not disabling all serial ports as it attempting to do.
"-serial none" was first introduced to Zephyr in this commit:
0b54f984b8
As far I can tell, pinging an echo_server works fine without it, so I
suspect that our second -serial flag is overriding it and that it has
no effect.
