we are using segger RTT protocol over shared memory for two core log/trace: one is NuttX another Linux/Windows. But the base address of shared memory can only be known at runtime, so we change SEGGER_RTT_UNCACHED_OFF from macro to global variable, and update to the correct g_segger_offset after the shared memory is initialized by:
g_segger_offset = (uintptr_t)ishmem - (uintptr_t)&_SEGGER_RTT;

Initial implementation of RFC 5424 support (syslog protocol). Allows
users to force-format the syslog output in a RFC 5424 compatible way,
making NuttX systems 'originators' that are able to interface with
syslog 'collectors' and 'relays' (useful for logging to syslog servers).
In addition to regular formatting options for syslog output, users can
also add structured data (currently only timeQuality is implemented,
assuming no sync and no timezone is no known). Facilities and severities
now also follow RFC 5424. Support for additional features (like
more sdata elements, msgid, etc.) will need to be built into the syslog
implementation if desired.
This patch is a rework of the NuttX file descriptor implementation. The
goal is two-fold:
1. Improve POSIX compliance. The old implementation tied file description
to inode only, not the file struct. POSIX however dictates otherwise.
2. Fix a bug with descriptor duplication (dup2() and dup3()). There is
an existing race condition with this POSIX API that currently results
in a kernel side crash.
The crash occurs when a partially open / closed file descriptor is
duplicated. The reason for the crash is that even if the descriptor is
closed, the file might still be in use by the kernel (due to e.g. ongoing
write to file). The open file data is changed by file_dup3() and this
causes a crash in the device / drivers themselves as they lose access to
the inode and private data.
The fix is done by separating struct file into file and file descriptor
structs. The file struct can live on even if the descriptor is closed,
fixing the crash. This also fixes the POSIX issue, as two descriptors
can now point to the same file.

The ADS1115 driver uses the `nxsig_usleep()` function to sleep for a
65us delay, but with a 1ms tick resolution and the context-switching
overhead, this is much more than 1ms. Introducing `up_udelay` (even with
a larger duration because of the unreliability of busy-waiting) speeds
up sampling noticeably.

Add support for BME688 sensor based on BME680 implementation.
The BME688 is nearly identical to the BME680, and this implementation
reuses much of the existing BME680 code. However, there are some differences
related to gas measurements that make it impractical to use the same driver
without significantly complicating it. BME688 also supports parallel mode
which isn't yet supported.

So far the NuttX implementation of OP-TEE has been using
registered memory references to pass non-registered memory
to OP-TEE OS, passing the physical address of the memory
in what is normally used as a 'cookie'. This was compatible
with the Openvela framework, but no other OP-TEE OS.
Fix this by passing temporary memory instead with the standard
non-contiguous (OPTEE_MSG_ATTR_NONCONTIG) flag.

Previous implementation was not compatible with GlobalPlatform
API in the following ways:
- Registered mem IDs would begin from negatives when it should
have been greater than or equal to 0
- Register IOCTL would return 0 on success, when it should have
been returning a file descriptor.
- Register IOCTL would expect the user-space client to specify
TEE_SHM_* flags dictating its behaviour when in fact, libteec
never specifies flags.
This commit fixes all those issues. It uses nuttx/idr.h instead
of a linked list, and it uses `file_allocate` to provide file
descriptors for registered shared memory. Upon close(fd), the
memory is de-registered and freed accordingly. It also updates
the documentation accordingly.

So far NuttX has supported OP-TEE interfacing over
local and RPMsg sockets. This commit introduces support
for direct invocation of OP-TEE through arm SMCs. The
SMC transport is enabled through CONFIG_DEV_OPTEE_SMC.
This SMC implementation has been tested only with arm64,
OP-TEE rev 4.4.
Note that it does not support reverse direction RPCs,
i.e. from the Secure World to the Normal World to
something like optee supplicant. A basic RPC handling
skeleton is provided with implementation for some
basic functions (alloc/free mem, and foreign interrupts)
but no supplicant command handling.

Adds support for SHM_REGISTER IOCTL. Registration can
be requested both against the driver (for automatic cleanup)
and against the secure OS (for sharing).
Introduces also `optee_{msg,free}_alloc()` to allocate
aligned memory for message arguments depending on the
`alignment` specified in the driver's private data. For
alignment greater than word size, memory is allocated on the
heap, otherwise it's allocated on the stack (similar to the
previous implementation but using `alloca()` instead).
