Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

761ee81956 move readv/writev to the kernel
currently, nuttx implements readv/writev on the top of read/write.
while it might work for the simplest cases, it's broken by design.
for example, it's impossible to make it work correctly for files
which need to preserve data boundaries without allocating a single
contiguous buffer. (udp socket, some character devices, etc)

this change is a start of the migration to a better design.
that is, implement read/write on the top of readv/writev.

to avoid a single huge change, following things will NOT be done in
this commit:

* fix actual bugs caused by the original readv-based-on-read design.
  (cf. https://github.com/apache/nuttx/pull/12674)

* adapt filesystems/drivers to actually benefit from the new interface.
  (except a few trivial examples)

* eventually retire the old interface.

* retire read/write syscalls. implement them in libc instead.

* pread/pwrite/preadv/pwritev (except the introduction of struct uio,
  which is a preparation to back these variations with the new
  interface.)

moving mmap beforee truncate could make three struct more compatible

6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

a830d59da2 This commit brings in a complete, but untested, implementation of a driver for the TI TDA19988 HDMI Encoder. This encoder is used on the Beaglebone Black board. Since this driver is untested, it requires CONFIG_EXPERIMENTAL in the configuration.
Squashed commit of the following:

    drivers/lcd/tda19988.c:  Numerous changes for a clean compilation.

    drivers/lcd/tda19988:  Bring in the final pieces from the FreeBSD TDA19988 driver.  The driver is now code complete.

    drivers/lcd/tda19988.c:  Flesh on EDID read logic (still not complete).  Add unlink shutdown logic.

    drivers/lcd/tda19988.c:  Add logic to read one EDID block.

    drivers/lcd/tda19988.c:  Add tda19988_read_edid() interface.  Flesh read() and seek() methods.

    drivers/lcd/st7032.c:  Fix another error in seek method:  Does not account for negative offsets!

    drivers/lcd/tda19988.c:  Add basic IOCTL infrastructure to support configuratin the video mode.  Mostly just a framework for now.

    drivers/lcd/tda19988.c:  Add more register definitions.  Encode page+address in the same was as FreeBSD.

    drivers/lcd/tda19988.c:  Add support for CEC messaging.

    drivers/lcd/tda19988.c:  Implement the unlink method.  No IOCTLs defined yet.

    drivers/lcd/tda19988.c:  Add placeholders for missing character driver methods.

    drivers/lcd/tda19988.c:  Trivial interface improvement to permit reading multiple TDA19988 registers.

    drivers/lcd/tda19988.c:  Feeble start of TCA19988 drivers.  Consists of lower half interface definition and some I2C helper functions.  Nothing more.
