* Check CAN DLC length value

* Fix default interface ID only being used partially

If user sets the default interface ID for a socket (e.g. using setsockopt
with SOCKET_INTERFACE_SELECT), the default interface should take over
other interface selection mechanisms as a interface is bound to the socket.
This applies for both IPv6 local and global scopes for unicast messages
but not for multicast messages as these are bound to a multicast interface
using SOCKET_IPV6_MULTICAST_IF socket option.

* Targets: NXP: IMXRT: Fixed GCC_ARM lds syntax.

Signed-off-by: Yilin Sun <imi415@imi.moe>

* CAN: read only up to 8 bytes

If HAL implementation writes more than 8 bytes of data, error immediately.
CANMessage defines only 8 bytes of data, lenght cannot be > 8.

* M467: Support CAN bus

1.  Update BSP CANFD driver
2.  Notes for implementation
    (1) Each CANFD instance supports two IRQ lines. Use only line 0. Line 1 is not used.
    (2) For Rx disabling multiple filter handles,
        1)  Map all filter handles to filter handle 0
        2)  Use Rx FIFO 0 for filter handle 0
    (3) For Rx enabling multiple filter handles,
        1)  Use Rx FIFO 0 for filter handle 0
        2)  Use Rx FIFO 1 for filter handle through first invoking can_filter()
        3)  Use dedicated Rx Buffer for other filter handles
        NOTE: H/W supports mask on Rx FIFO 0/1 but not on dedicated Rx Buffer.
    (4) For Tx, use only dedicated Tx Buffer. BSP CANFD driver doesn't support Tx FIFO/Queue.
    (5) Support no CAN FD.

* Fix 'new[]' array freed with 'delete'

The array _scratch_buf is allocated using new[] in line 761 of
mbed-os/storage/kvstore/securestore/source/SecureStore.cpp.
But it was freed using delete.

* Define default parameters of functions of derived class the same as the base class

The member function bringup() of class ThreadInterface redefines
parameter stack's default value to IPV6_STACK from the inherited default value
DEFAULT_STACK (in Interface).
The default value will be resolved statically, not by dispatch, so this
can cause confusion.
Similar arguments apply to LoWPANNDInterface and WisunInterface.

* Avoid calling virtual functions from constructors and destructors

Virtual functions are resolved statically (not dynamically) in
constructors and destructors for the same class. The call should be made
explicitly static by qualifying it using the scope resolution operator.

* Fix potentially overrunning write of sprintf

Format string "%d" requires 12 bytes (including the null terminator).
Also, use snprintf instead of sprintf to prevent buffer overflow.

* Fix system_clock.c location

Signed-off-by: Jasper Jonker <jasper.jonker@wingtra.com>

* Fix variable name

Signed-off-by: Jasper <jasper.jonker@wingtra.com>

* Change storage-class of secret_buf to static

Storing the address of a local variable (`secret_buf`)
in non-local memory (`prf_ptr->secret`) can cause a
dangling pointer bug if the address is used after the function returns.

* fix compiling errors of FATFileSystem when exFAT was enabled

* Add OSPI support for STM32H7

* Nuvoton: Enable extending sampling time for ADC/EADC

For all Nuvoton targets, enable extending sampling time in ADC/EADC clocks on per-pin basis.

* Disable LPTICKER on MIMXRT1060, fix pin names for newer dev kits

* Enable MIMXRT106x ethernet

Merge upstream changes into mbed-ce (#117) ...

* Fix for calculating CAN timing settings.

NominalPrescaler value needs to be as high as possible to ensure a good approximation of the target CAN speed.
Previous usage of macro IS_FDCAN_DATA_TSEG1 refers to (unsupported by Mbed ) FDCAN CAN controller settings and leads to too low prescaler values.
Usage Macro IS_FDCAN_NOMINAL_TSEG1 yields optimum results.
See also correct macro usage in line #158.

* Add complete support of DHCP relay interface ID option

RFC3315 specifies the following: "The relay agent MAY send the Interface-id
option to identify the interface on which the client message was received.
If a relay agent  receives a Relay-reply message with an Interface-id
option, the relay agent relays the message to the client through the
interface identified by the option."

The current implementation of the DHCP relay reply handling, the interface
ID field from the server response is ignored. Managing the interface ID
is very important especially as DHCP requests/replies use link-local
addresses. The consequence of this is that the interface must always be
specified because the routing layer cannot guess the correct interface.
Moreover, Mbed provides a mechanism to enable/disable the interface ID
option on a DHCP relay instance, so it is important to fully support it.

The reason why this issue has not been discoverd until now is that the DHCP
relay is mainly used on systems that use only one interface (such as Wi-SUN
routers). By default, when no interface ID is specified for the socket, the
latter will choose 6loWPAN interface by default. This means that if two
interfaces are used on the same device, the 6loWPAN interface is always
selected.

The commit adds code to retrieve the interface-id value contained within
the DHCP relay reply message and write it to a control message header
that is added to the socket message. This tells the socket which
interface to choose. If the interface-id option is not enabled on the
relay, this procedure is simply ignored.

* Support Nuvoton target NUMAKER_IOT_M467

1.  Based on alpha version BSP (85564a2)
2.  Continuing above, tweak BSP:
    (1) Add EPWM_ConfigOutputChannel2() to enable below 1Hz and below 1% duty cycle for PWM output (m460_epwm.h/c).
    (2) Add dummy RTC_WaitAccessEnable() for consistency with previous ports (m460_rtc.h).
3.  Target NuMaker-M467HJ V0.1 board temporarily
4.  Support Arduino UNO form factor for NUMAKER_IOT_M467 target
5.  Enable export to Keil/IAR project
    -   tools/arm_pack_manager/index.json
    -   tools/export/iar/iar_definitions.json

* M467: Fix Greentea reset_reason test failure

HRESETRF is combined reset flag. Filter it out to avoid interference with reset reason check.

* M467: Support HyperRAM

1.  For GCC, support multi-block .data/.bss initialization
2.  HyperRAM is mapped to two regions: 0x0A000000 and 0x80000000
    According to default system address map, 0x0A000000 is located at 'Code' region and 0x80000000 at 'RAM' region.
    With MPU enabled on Mbed OS, 'Code' region is write-never and 'RAM' region execute-never.
    0x80000000 is chosen because 'RAM' regioin is naturally for HyperRAM.
3.  Configurable multi-function pins for HBI
4.  To locate code/data at external HyperRAM:
    -   Specify __attribute__((section(".text.nu.exthyperram"))) for RO/.text/readonly section type
        Invoke mbed_mpu_manager_lock_ram_execution()/mbed_mpu_manager_unlock_ram_execution() to run HyperRAM code
    -   Specify __attribute__((section(".data.nu.exthyperram"))) for RW/.data/readwrite section type
    -   Specify __attribute__((section(".bss.nu.exthyperram"))) for ZI/.bss/zeroinit section type
5.  Add readme

* Config for M460 EMAC

* Add M460 EMAC driver

* Adjust M460 EMAC RX/TX buffer

* M467: Fix EMAC compile error with IAR

* M467: Support Crypto SHA/ECC H/W

1.  Prepare crypto common code
2.  Support list
    -   SHA
    -   ECC
    NOTE: AES/RSA are to support in other works
    NOTE: Compared to M487, M467's SHA supports context save & restore (DMA Cascade mode) and so no software fallback is needed.
    NOTE: M467's ECC, following M487, goes partial-module replacement and it can just improve primitives e.g. point addition/doubling by 2X,
          and cannot improve high level point multiplication because MbedTLS doesn’t open it.
          To improve performance best, full-module replacement is needed.
    NOTE: Continuing above, add support for Montgomery curve

* M467 H/W AES self-test pass

* M467 Support crypto GCM H/W

* M467: GCM support one simple mode instead of using composite GHASH & CTR MODE

* Update M467 AES-GCM to pass AWS-IoT test

* Update M467 AES-GCM for H/W gcm in-buffer creteria

* M467: Improve Crypto H/W wait helper routine

Add crypto_xxx_wait2 helper routine to replace crypto_xxx_wait for Crypto H/W control

* M467: Seed PRNG with TRNG for SCAP

According to TRM, it is suggested PRNG be seeded by TRNG on every Crypto H/W reset.

* M467: Support Crypto RSA H/W

1.  Crypto RSA H/W supports 1024/2048/3072/4096 key bits. Fall back to software implementation for other key bits.
2.  For decrypt, if MBEDTLS_RSA_NO_CRT isn't defined, go CRT, or normal.
3.  For decrypt, when blinding (f_rng != NULL), enable SCAP mode.
4.  Recover from Crypto RSA H/W failure:
    (1) Enable timed-out wait to escape from RSA H/W trap
    (2) On RSA H/W timeout, stop this RSA H/W operation
    (3) Fall back to S/W implementation on failure

NOTE: RSA 4096 key bits can fail with default mbedtls configuration MBEDTLS_MPI_MAX_SIZE.
      Enlarge MBEDTLS_MPI_MAX_SIZE to 1024 or larger if this feature is required.
NOTE: Fixed in BSP RSA driver, for non-CRT+SCAP mode, temporary buffer for MADDR6 requires to be key length plus 128 bits.
NOTE: Fixed in BSP RSA driver, DMA buffer must be 4-word aligned, or RSA H/W will trap.

* M467 Support crypto AES-CCM H/W with one-shot & cascade mode

* M467: Support Crypto ECC H/W in full-module replacement

1.  Replace ecp.c full-module, and other ec modules dependent on ecp.c (ecdh.c/ecdsa.c/ecjpake.c) will improve followingly.
2.  Recover from Crypto ECC H/W failure:
    (1) Enable timed-out wait to escape from ECC H/W trap
    (2) On ECC H/W timeout, stop this ECC H/W operation
    (3) Fall back to S/W implementation on failure
3.  Support Short Weierstrass curve
4.  Support Montgomery curve
    Montgomery curve has the form: B y^2 = x^3 + A x^2 + x
    (1) In S/W impl, A is used as (A + 2) / 4. Figure out its original value for engine.
        https://github.com/ARMmbed/mbed-os/blob/2eb06e76208588afc6cb7580a8dd64c5429a10ce/connectivity/mbedtls/include/mbedtls/ecp.h#L219-L220
    (2) In S/W impl, B is unused. Actually, B is 1 for Curve25519/Curve448 and needs to configure to engine.
        https://github.com/ARMmbed/mbed-os/blob/2eb06e76208588afc6cb7580a8dd64c5429a10ce/connectivity/mbedtls/include/mbedtls/ecp.h#L221-L222
    (3) In S/W impl, y-coord is absent, but engine needs it. Deduce it from x-coord following:
        https://tools.ietf.org/id/draft-jivsov-ecc-compact-05.html
        https://www.rieselprime.de/ziki/Modular_square_root
    NOTE: Fix Curve448 has wrong order value

MPS2 CM3DS ethernet words instead of bytes ...

The functions smsc9220_receive_by_chunks and smsc9220_send_by_chunks are
supposed to implement receiving and sending packets by chunks. However,
the functions SMSC9220_EMAC::low_level_input and SMSC9220_EMAC::link_out,
which call them respectively, already require or assemble the full packet.
Also, smsc9220_receive_by_chunks doesn't implement the "chunks" part.

This commit renames the functions to smsc9220_receive_packet and
smsc9220_send_packet. The functions now do their operations by word
instead of by bytes. The functions SMSC9220_EMAC::low_level_input and
SMSC9220_EMAC::link_out already handle allocation, continuity and word
alignment of the packet buffer.

MPS2 CM3DS ethernet fix heap bug ...

The function SMSC9220_EMAC::low_level_input should create a heap for the
packet equal to the size of the message (most of which are couple hundred
bytes). The current code uses maximum frame size (1522 bytes) for each
packet. This will cause the heap to quickly fill up. In fact, the default
memory size (lwip.mem-size) used for this heap is 1600 bytes. This means
that once you have one other packet allocated (extremely common), the
heap allocation will always fails.

Also, it is recommend to increase the default lwip.mem-size because that
amount is very small especially if you send or receive a few large packets
in the network. This is NOT done in current commit.

MPS2 CM3DS ethernet fix deprecation warnings ...

The sleep_for function is updated to use the chrono time arguments since
the regular ones are deprecated.

ESP8266: Fix serial flow control inconsistency on reconnect ...

The commit will address the test failure of connectivity-netsocket-tests-tests-network-interface.
In the test, serial channel will break with the sequence: ESP8266Interface::connect() > disconnect() > connect()
In the first connect, both board's and ESP8266's serial flow control default to disabled, and then enabled.
In the second connect, board's serial flow control keeps enabled but ESP8266's resets to disabled, causing inconsistency between two ends.

The approach: Explicitly disable board's serial flow control on re-power or reset in (re-)connect

Fix STM32 radio driver when bandwith is 0 ...

A bug was detected when the uint8_t SUBGRF_GetFskBandwidthRegValue( uint32_t bandwidth )
is called and the bandwith argument has a value of 0.

Comparing the code to the STMCubeWL 1.1 we can see that an if statement is missing to
address the condition where bandwith is equal to 0.

Added the if statement to the radio driver to account for this edge case.
