Fix an issue that math library header files are not exported by make export.
Create symbolic links of libmcs, newlib and openlibm header to nuttx/include.
The driver's main purpose is to support the porting of the open source
component optee_client (https://github.com/OP-TEE/optee_client) to nttux.
The basic function of the driver module is to convert the REE application layer data and send it to the TEE through rpmsg.
The main functions include
1 driver registration.
we need to register a device driver(/dev/tee0) through optee_register function.
2 open the driver
3 ioctl the driver
The ioctl command passes different parameters and commands, and interacts with the TEE through rpmsg.
4 close the driver

PR #11165 causes an unnecessary regression; task_delete no longer works,
if the deleted task is from another group.
The logic that prevents this comes from:
nxnotify_cancellation() ->
tls_get_info_pid() ->
nxsched_get_stackinfo()
Which checks for permissions, which does not make sense in this case since
it is the kernel asking for the stack information.
Fix this by partially reverting 11165 and implementing a direct path for
the kernel to query for any tasks TLS.
Replace DEBUGASSERTs with sanity checks. DEBUGASSERT()s are
not necessarily enabled at all, thus risking the functionality
especially in that case. Remove PANICs as well.
Don't enable the ihc irq too early. If enabled, and the master
is already up, the irq is being issued so that the system gets
stuck or is severely slowed down. Master may be already up if
this NuttX hart only is rebooted, for example.

Commit 9244b5a737 added support
for non-standard field si_user that is useful for passing context
pointers to signal handlers.
This commits makes it work for all signals, not just SA_KERNELHAND.
Previously si_user for normal signals was uninitialized garbage.
newsize = newsize + CONFIG_FS_TMPFS_FILE_ALLOCGUARD;
When newsize is a large value,
adding a relatively small value can cause the result to become very small,
resulting in program logic errors.
For example:
0xffffffff + 0x2 = 1

There are ICs available on the market that integrate various power inverter
features. The driver for such a device must be tightly coupled to a FOC device
as using it as a separate device doesn't make sense.
Adds support for hardware timestamping of received Ethernet packets.
The timestamp is available to applications using socket option SO_TIMESTAMP.
Optionally, the Ethernet PTP timer can be used as system high-resolution RTC.
In this mode it supports fine resolution rate adjustment.
Alternatively other time source for CLOCK_REALTIME can be used, and the
PTP timestamps are converted by sampling the clocks and computing the
difference. This results in a few microseconds of uncertainty.
Adds support for timestamping received UDP packets, either in
hardware or in kernel. Builds on the existing support of SO_TIMESTAMP
for SocketCAN.
Implementation uses CLOCK_REALTIME for timestamping to match the
behavior of Linux. This could be made configurable in future if needed.
