Support Nuvoton targets



Based on mbed-os-pelion-example master/mbed-bootloader 4.1.0/mbed-cloud-client 4.0.0,

support Nuvoton targets:

1.  Support Nuvoton targets:

    -   NUMAKER_PFM_NUC472

    -   NUMAKER_PFM_M487

    -   NUMAKER_IOT_M487 V1.3

        Compared to V1.2, V1.3 adds support for ESP8266 RTS/CTS/RST pins. V1.3 is incompatible with V1.2 on ESP8266.

    -   NUMAKER_IOT_M263A

2.  Change storage to NUSD (SD card in SDIO bus mode) from SD (SD card SPI bus mode)

    (1) Add COMPONENT_NUSD.lib.

    (2) Add component NUSD (target.components_add).

    (3) Change default BlockDevice to NUSD:

        Override BlockDevice::get_default_instance (nusd.provide-default-blockdevice).

        Required since mbed-cloud-client 2.1.0 (arm_uc_blockdevice_ext) or in:

        mbed-bootloader/modules/storage/pal-blockdevice/source/arm_uc_pal_blockdevice_mbed.cpp

    (4) Enable kvstore with blockdevice type being "other".

        i)  Override get_other_blockdevice() (nusd.provide-kvstore-other-blockdevice).

        ii) Configure storage type to "FILESYSTEM".

        iii)Configure file system type to "LITTLE".

        vi) Configure block device type to "other".

        v)  Configure external size to 64MiB, which cannot overlap with update-client.

            storage-address/update-client.storage-size.

3.  Change back UARTSerial tx/rx buffer size from 1024/1024 to 256/256. This can reduce

    memory footprint by (1024 - 256) * 2 = 1.5KiB. Because this configuration influences

    both ESP8266 and default console (platfrom/mbed_retarget.cpp), memory reduction can

    achieve 1.5KiB x 2 = 3KiB.

4.  Enlarge ESP8266 'send tcp data' timeout on Nuvoton targets

    Pelion connection has some failure rate with this. Enlarging ESP8266_SEND_TIMEOUT

    can just relieve the issue. A ticket has raised to address it:

    https://github.com/ARMmbed/mbed-os/issues/11544

5.  Requirements for mbed-os version:

    -   mbed-os 5.13.0 (or afterwards) to support kvstore with block device type being "other"

    -   mbed-os 5.13.1 (or afterwards) to fix 'undefined pal_plat_osEntropyInject(...)' error

    -   mbed-os 5.14.0 (or afterwards) to support NUMAKER_IOT_M263A
