The sysbuild part of sysbuild/application creates a sysbuild/application
folder under top-level build dir. However, having a sysbuild folder at
this level means that tab completion for sysbuild pre-fixed build
targets will stop after completing just `sysbuild` and then show several
subfolders, making it hard to see important build targets, such as:
`ninja sysbuild_menuconfig`.
As `sysbuild/application` is just a folder name, then move it to
`_sysbuild` instead to avoid impacting tab completion for ninja and
make.
Also strip the `application` part in the process, as the extra folder
doesn't provide any extra benefit, but is just one more level to enter
when browsing the build folder structure.

`west build` can be invoked without specifying the source directory when
being invoked from the source directory itself.
When using `west build` for incremental builds, then the build command
will examine the CMake cache to determine the application dir by using
the value of CMAKE_HOME_DIRECTORY.
With sysbuild, this leads to the wrong assumption that the sysbuild
itself is the application to build.
Instead, have west build look for APP_DIR which points to the correct
source dir when sysbuild is used. Use APPLICATION_SOURCE_DIR when
APP_DIR is not set, as this indicates a no-sysbuild build.
Keep CMAKE_HOME_DIRECTORY behavior as last fallback mechanism.

If compiler optimizations are disabled, some compilers (especially
arm_cortex_m) are using unrealistic amounts of stack for dead code.
Currently, if CONFIG_LOG=y and CONFIG_NO_OPTIMIZATIONS=y,
CONFIG_LOG_ALWAYS_RUNTIME is enabled to reduce the stack used by the
logging code.
However, if CONFIG_LOG=n, CONFIG_LOG_ALWAYS_RUNTIME is not available
which causes the compiler to allocate lots of stack space for the (dead)
logging code.
This patch forces runtime message creation when CONFIG_LOG=n. Since all
logging code is dead code when logging is disabled, the behavior should
be unchanged.

Implement absolute minimum necessary to get Buffer DMA working. Require
Data Cache to be disabled if DWC2 OTG has DMA enabled because the stack
does not currently guarantee cache line alignment for allocated buffers.
Set EPENA bit before disabling IN endpoints because it seems to be
necessary in Buffer DMA mode (without EPENA the wait for INEPNAKEFF does
time out). Setting EPENA should have no impact on Completer mode
operation (where EPENA is not necessary for INEPNAKEFF to trigger).
Programming Guide recommends programming SUPCnt to 3, but the only
advantage would be to be able to tell how many back-to-back SETUP packets
were received if there was no more than 3 back-to-back SETUPs. This
information doesn't seem to be useful. The disadvantage is that the
buffer needed for receiving SETUP packet must be able to hold SUPCnt
multiple of 8 bytes. Use SUPCnt 1 so the 8 bytes buffer is enough.
Make sure to clear StsPhseRcvd interrupt bit in Buffer DMA mode because
the DMA seems to prevent the SETUP Phase Done interrupt from triggering
if StsPhseRcvd is set. Clearing this bit doesn't seem to be necessary in
Completer mode. This bit is set on control transfers with data stage
from host to device.
Both Buffer DMA and Completer mode operation on nRF54H20DK was verified
using USB2CV Chapter 9 Tests and MSC Tests with Mass Storage sample.

Add an optional DT property to specify the size of the RX/TX FIFO
implemented within the SPI core. The property name used is the same one
used by Xilinx's device tree generator.
When the FIFO is known to exist, we can use the RX FIFO occupancy register
to determine how many words can be read from the RX FIFO without checking
the RX FIFO empty flag after every read. Likewise with the TX FIFO, we can
use the FIFO size to avoid checking the FIFO full flag after every write.
This can increase overall throughput.

Add support for a workaround required when using the Xilinx Quad SPI core
with the USE_STARTUP option, which routes the core's SPI clock to the
FPGA's dedicated CCLK pin rather than a normal I/O pin. This is typically
used when interfacing with the same SPI flash device used for FPGA
configuration. In this mode, the SPI core cannot actually take control
of the CCLK pin until a few clock cycles are issued, which would break
the first transfer issued by the core. This workaround applies a dummy
command to the connected device to ensure that the clock signal is in the
correct state for subsequent commands.

There actually is no triple faults on Xtensa. Once PS.EXCM is
set, it keeps going through double exception vector for any
new exceptions. However, our exception code needs to unmask
PS.EXCM to enable register window operations. So after that,
any new exceptions will go through the kernel or user vectors
depending on PS.UM. If there is continuous faults, it may
keep ping-ponging between double and kernel/user exception
vectors that may never get resolved. Since we stash DEPC
during double exception, and the stashed one is only cleared
once the double exception has been processed, we can use
the stashed DEPC value to detect if the next exception could
be considered a triple fault. If such a case exists, simply
jump to an infinite loop, or quit the simulator, or invoke
debugger.

arch_user_string_nlen() did not exactly work correctly as any
invalid pointers being passed are de-referenced naively, which
results in DTLB misses (MMU) or access errors (MPU). However,
arch_user_string_nlen() should always return to the caller
with appropriate error code set, and should never result in
thread termination. Since we are usually going through syscalls
when arch_user_string_nlen() is called, for MMU, the DTLB miss
goes through double exception. Since the pointer is invalid,
there is a high chance there is not even a L2 page table
associated with that bad address. So the DTLB miss cannot be
handled and it just keeps looping in double exception until
there is another exception type where we get to the C handler.
However, the stack frame is no longer the frame associated
with the call to arch_user_string_nlen(), and the call return
address would be incorrect. Forcing this incorrect address as
the next PC would result in some other exceptions, e.g.
illegal instruction, which would go to the C handler again.
This time it will go to the end of handler and would result
in thread termination. For MPU systems, access errors would
simply result in thread terminal in the C handler. Because of
these reasons, change the arch_user_string_nlen() to check if
the memory region can be accessed under kernel mode first
before feeding it to strnlen().
Also remove the exception fixup arrays as there is nothing
there anymore.

If there are any TLB misses during interrupt handling,
the user, kernel and double exception vector will be triggered
for the miss and the DEPC and EXCCAUSE overwritten as the TLB
missse are be handled in the assembly code and execution
returned to the original vector code. Because of this, both
DEPC and EXCCAUSE being read in the C handler are not the ones
that triggered the original exception (for example, level-1
interrupt). So stash both DEPC and EXCCAUSE such that
the original cause of exception is visible in the C handler.
