* Remove all source files exclusive to Arm Compiler and IAR

* Also remove 'TOOLCHAIN_ARM'

* Remove targets.json entries for ARM and IAR

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.

* 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

Removed UTF-8 Chars

Updated System file and Scatter file

Updated I2C pin names in PinNames.h header

GPIO: Use uintptr_t for gpio_irq_api context ...

The HAL gpio_irq_api stores object IDs, which serve as a form of context
for the dispatch of the interrupt handler in the drivers level
InterruptIn Class. The way this is achieved is that the InterruptIn
Class casts its address to uint32_t, which is stored as the ID.
This results in compilation failure when the size of an object pointer
is greater than uint32_t, for example when building on a PC for unit
testing.

In order to allow Unit Testing of the InterruptIn Class, we replace the
use of uint32_t with uintptr_t (type capable of holding a pointer),
which allows portability and expresses intentions more clearly.
In aid of this latter goal, we also replace the use of the name "id"
with "context", to improve clarity - these are addresses of the context
related to that callback.

CMake: Create CMSIS library targets to remove dependency on MBED_TARGET_LABELS ...

This goes towards eventually removing reliance on targets.json to specify
the requirements of Mbed targets.

CMake: Refactor Toshiba targets ...

Refactor all Toshiba targets to be CMake buildsystem targets. This removes
the need for checking MBED_TARGET_LABELS repeatedly and allows us to be
more flexible in the way we include MBED_TARGET source in the build.

A side effect of this is it will allow us to support custom targets
without breaking the build for 'standard' targets, as we use CMake's
standard mechanism for adding build rules to the build system, rather
than implementing our own layer of logic to exclude files not needed for
the target being built. Using this approach, if an MBED_TARGET is not
linked to using `target_link_libraries` its source files will not be
added to the build. This means custom target source can be added to the
user's application CMakeLists.txt without polluting the build system
when trying to compile for a standard MBED_TARGET.

stack: armc: Workaround config passing bug ...

Workaround a bug where the boot stack size configuration option is not
passed on to armlink, the Arm Compiler's linker. Prefer
MBED_CONF_TARGET_BOOT_STACK_SIZE if present, as this is what the
configuration system should provide. Fall back to MBED_BOOT_STACK_SIZE
if MBED_CONF_TARGET_BOOT_STACK_SIZE is not defined, as in the case of
buggy tools. If both MBED_CONF_TARGET_BOOT_STACK_SIZE and
MBED_BOOT_STACK_SIZE are not defined, then we fall back to a hard-coded
value provided by the linkerscript. See
https://github.com/ARMmbed/mbed-os/issues/13474 for more information.

Use boot stack size from config system ...

To allow overriding of the boot stack size from the Mbed configuration
system, consistently use MBED_CONF_TARGET_BOOT_STACK_SIZE rather than
MBED_BOOT_STACK_SIZE.
