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.
(+one minor change s/parm/param in arch/arm64/include/syscall
to satisfy the spellchecker during PR)

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).

Besides a few checks for NULL IOCTL argument values, this
commits introduces also a check to ensure that user specified
memory (mainly IOCTL arguments) indeed belongs to the user.
This is applicable only with `CONFIG_ARCH_ADDRENV`.

The MCP47X6 series consists of the following single channel DAC chips:
- MCP4706 (8 bit)
- MCP4716 (10 bit)
- MCP4726 (12 bit)
The driver supports the following configurations:
- gain
- power down
- voltage reference
Persistent configuration storage in the internal EEPROM is not
implemented.
ax99100 export each serial port as a separate PCI device function
so we have to handle this properly.

This adds filters field to icjx_config_s structure that is passed
as an argument in icjx_initialize function. This field allows to
configure I/O filters (control world 1 and 3) with three possible
filters or disable them at all.
The filter configuration is currently only configurable during the
initialization, not at run time (the same as current source)

Add an option to completely disable syslog() and replace it with an empty functions.
This option can be useful for small systems when we don't have any logging support,
but compiler is not able to remove useless code.
This way the final image also won't contain the strings that are present in
syslog() calls when compiler optimization is enabled (for example from /boards
where syslog is often used instead of debug macros).

To be compatible with the previous method, add a buf between cdcacm
and serial. Because when using usbreqbuf directly as the buf of serial,
the amount of data sent may be insufficient due to the limit of the
number of reqs. For example, when the number of reqs is 4, the number
of data send through cdcacm is 5, and each data is a separate USB
packet, if the host does not read in time, resulting in blocking send.

Adds a device ID to ramtron_initialize, which is stored in the ramtron_dev_s structure.
This ID is used when calling SPI_SELECT to board specific logic to allow chip select on the SPI bus.
This change is NOT backwards compatible, as it changes the function signature of ramtron_initialize.
This implementation is based on the handling of chip select in nuttx/drivers/mtd/sst26.c:sst26_initialize_spi().
Additional Changes:
- Add MB85RS64V to ramtron supported parts list.
Using the FTL driver over a MTD flash device, when writing to flash, eventually the ftl_flush function is called and it does an erase (MTD_ERASE) and then the write (MTD_BWRITE). Currently, the at45db driver (at45db.c), uses a write command 0x82 ("Main Memory Page Program through Buffer 1 with Built-In Erase") that also performs a built-in erase before the write. In summary, each time a write to flash is performed, the page is erased twice before it is written, first in the FTL driver and then in the MTD driver.
This PR is to change the page writes to not use that built-in command.

examples:
There are two threads involved: thread A with a priority of 100 and
thread B with a priority of 101. Here's how they interact:
When thread A releases a semaphore, thread B is scheduled to execute
some code and may reacquire the semaphore. If no other tasks are ready,
thread A will be scheduled to run.
This continuous process can lead to a busy loop.
Thread A: Thread B:
while (nxsem_get_value(&priv->wait, &semcount) >= 0 && <---
semcount <= 0) | 2)context switch
{ 1)contex switch |
