When using a devicetree node as an identifier we know the identifier
used to define the device structure. This allows code to directly
reference that structure, avoiding the need to look it up by label at
runtime.
Change the macros so DEVICE_DT_* device objects are globally visible
using the node identifier as the object identifier.
Also add the necessary API to verify that a device that was captured
at build time successfully completed initialization and any other
steps necessary before it can be safely used.

For devices defined using devicetree nodes we need to pass the
devicetree node, and to infer names for the device and the driver from

node is invalid.

Introduce common API to achieve data transfer using system DMA.
"System DMA" uses the outbound memory mapped Host address,
it cannot understand Host/PCIe address.
This API will take of mapping the Host address, completing
the data transfer to/from Host memory and unmapping the window;
thus providing abstraction to the user.

For a given PCIe EP device, data transfer to/from Host memory can be
achieved with "System DMA" between mapped Host memory
(PCIe outbound memory) and EP device's local memory if EP is equipped
with a "System DMA controller".
Add public API to enable such DMA transfers.
The term "System DMA" is used to clarify that we are not talking about
dedicated "PCIe DMA"; rather the one which does not understand PCIe
address directly, and uses the mapped Host memory.

This commit adds a new driver category for memory controller
peripherals. There is no API involved for now, as it has not been found
necessary for first implementation.
STM32 Flexible Memory Controller (FMC) is the only controller supported
for now. This peripheral allows to access multiple types of external
memories, e.g. SDRAM, NAND, NOR Flash...
The initial implementation adds support for the SDRAM controller only.
The HAL API is used, so the implementation should be portable to other
STM32 series. It has only been tested on H7 series, so for now it can
only be enabled when working on H7.
Linker facilities have also been added in order to allow applications to
easily define a variable in SDRAM.

"The macros ALIGN_H() and ALIGN_D(), which are implementation
dependent, round their arguments up to the next even multiple of
whatever alignment is required for the start of the cmsghdr structure

%i0 is the function argument "addr". %g1 is prepared with the value
0xfe800000. The "clrb" instruction sets a single byte in memory to
0 and has no alignment restriction.
We get an unaligned exception on PC 400089e0 when %i0 ("addr") is
not a multiple of 4. The instruction "st" stores the full 32-bit
register %g1 to memory address in %i0. The effective address (%i0)
of the 32-bit register store is required to be naturally aligned by
the architecture.
The compiler assumes that "addr" is aligned according to its type
and has knowledge about the data representation.

There are x86 platforms where the IRQ configuration register for PCIe
is not pre-populated and the OS needs to assign a number dynamically
by writing to the register.
In order to allocate interrupts we have to know which ones have been
hard-coded in device tree. We accomplish this by collecting these
values through the IRQ_CONNECT() macro and placing them in a dedicated
linker section (in ROM).
The full set of allocated interrupts are managed through a bitmap, and
the pre-allocated values (from the linker section) are inserted into
this upon initial runtime access.
This patch introduces a new pcie_alloc_irq() API that drivers can use
to allocate interrupt line numbers. The two in-tree drivers that were
using this API (I2C and UART) are converted to use the new API.

SPARC is an open and royalty free processor architecture.
This commit provides SPARC architecture support to Zephyr. It is
compatible with the SPARC V8 specification and the SPARC ABI and is
independent of processor implementation.
Functionality specific to SPRAC processor implementations should
go in soc/sparc. One example is the LEON3 SOC which is part of this
patch set.
The architecture port is fully SPARC ABI compatible, including trap
handlers and interrupt context.
Number of implemented register windows can be configured.
Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic
instructions from SPARC V9. An option has been defined in the
architecture port to forward the corresponding code-generation option
to the compiler.
Stack size related config options have been defined in sparc/Kconfig
to match the SPARC ABI.
