UDPSocket can be used also similar to TCPSocket using connect(), send() and recv() methods.
This commit adds UDP ECHOTESTS which uses these methods instead of sendto() and recvfrom().
When using MbedCRC, init value must be non-reversed, regardless of
`reflect_data` or `reflect_out` settings. This means we need to reflect
the intermediate output before passing using it as the next init value.
(In GCC this ends up putting in two `RBIT` instructions back-to-back,
because it's implemented as assembler, so it doesn't know how to
optimise. In ARMC6, `__RBIT` is implemented as an intrinsic, so adding
this reflection cancels the existing reflection and makes the code
smaller).
* Make mbed_error use bitwise MbedCRC call rather than local
implementation.
* Remove use of POLY_32BIT_REV_ANSI from LittleFS.
* Move some MbedCRC instances closer to use - construction cost is
trivial, and visibility aids compiler optimisation.
* Use compile-time detection of hardware CRC capability, so unneeded
code and tables do not go into the image.
* Add global JSON config option to allow choice between no tables,
16-entry tables or 256-entry tables for software CRC. Default set
to 16-entry, reducing ROM size from previous 256-entry.
* Allow manual override in template parameter to force software or
bitwise CRC for a particular instance.
* Micro-optimisations, particularly use of `RBIT` instruction and
optimising bitwise computation using inline assembler.
Incompatible changes:
* Remove special-case "POLY_32BIT_REV_ANSI" - users can use standard
POLY_32BIT_ANSI, which now uses the same 16-entry tables by default,
or can use hardware acceleration, which was disabled for
POLY_32BIT_REV_ANSI. MbedCRC<POLY_32BIT_ANSI, 32, CrcMode::TABLE> can
be used to force software like POLY_32BIT_REV_ANSI.
* The precomputed table for POLY_16BIT_IBM had errors - this has been
corrected, but software CRC results will be different from the previous
software calculation.
* < 8-bit CRC results are no longer are shifted up in the output value,
but placed in the lowest bits, like other sizes. This means that code
performing the SD command CRC will now need to use `(crc << 1) | 1`,
rather than `crc | 1`.
* Change "is supported" check to be a macro, so it can be done at
compile-time.
* Eliminate weird shift on 7-bit CRCs.
* Add support for 32-bit CRCs and reversals to TMPM3HQ.
As the `psa` library is not included in the baremetal profile, perform
a TFM system reset only if the `psa` library is included in
the build otherwise perform a normal CMSIS system reset.
