RDC module is used by i.MX8MM SoC, so let's create a Kconfig symbol
which will be used to enable the module in SDK.

Add support for the Cortex-M1 ARM DesignStart FPGA reference design
running on the Digilent Arty development board.
This board uses IRQ 7 (the last IRQ) as a level-detect non-interrupt
signal to determine whether the V2C-DAPLINK shield is installed. This
IRQ line is always pending when the shield is not installed. Use IRQ 6
instead.

Add devicetree bindings for the Xilinx AXI GPIO v2 IP. This GPIO
controller has an optional "GPIO2" port, which is not always present.
The Xilinx specific devicetree property names and their meaning match a
subset of what can automatically be generated based on the FPGA logic
design using https://github.com/Xilinx/device-tree-xlnx. These
properties are also used by the Linux kernel.

The Wait For Interrupt (WFI) instruction ARM Cortex-M1 CPU does not

The Data Tightly Coupled Memory (DTCM) of the Cortex-M1 present in the
Cortex-M1 ARM DesignStart FPGA implementation is No-Execute (NX), so
__ramfunc linked in the DTCM will cause a hard fault when executed.
Use the Xilinx Block RAM (bram0) present in the reference design for
demonstrating __ramfunc instead.

Add function pointer to vtable and use that directly instead of
routing via ioctl() call. This is done as we are trying to get

Do not route close() calls via ioctl() as that is error prone
and quite pointless. Instead create a callback for close() in
fdtable and use it directly.

The on-off manager infrastructure is designed to robust asynchronous
transition between binary states where multiple clients may be
initiating a transition from any context. The actual transition is
performed using a manager that tracks the current state and pending
operations. Requests are initiated by passing a reference to an
onoff_client object that holds client state including the notification
mechanism.
This API may be used in subsystems where the transitions for a
particular driver are always synchronous and isr-ok, e.g. setting a
SoC-controlled GPIO. In this situation the full on-off manager
infrastructure is wasteful. All we need is a record of the service
state: off, active count, or error.
Add a data structure and an API that can be used to replace the onoff
manager functionality in a situation where all transitions are isr-ok
and synchronous while retaining compatible behavior from the client
perspective.

There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.
Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

In Github issue #27548 I found out that documentation has
incorectness. I made fix and described how correctly provide multiple
overlay files for west and cmake. For both of them necessary to use
quotations. After that, necessary to make one more change if you have
multiple files in quotations. For west necessary to separate multiple
files using spaces and for cmake to separate multiple files necessary
to use semicolons.

Its possible to rename the executable we build via the Kconfig symbol
CONFIG_KERNEL_BIN_NAME. So we really should use ${KERNEL_ELF_NAME},
${KERNEL_BIN_NAME} and ${KERNEL_HEX_NAME} variables instead of hardcoded
zephyr.elf, zephyr.bin, and zephyr.elf.
This fixes an build issue with
tests/misc/test_build/buildsystem.kconfig.utf8_in_values on
up_squared_adsp and lpcxpresso11u68 platforms.
