Add license identifier to files which Arm owns the copyright to,
and contain either BSD-3 or Apache-2.0 licenses. This is to address
license errors raised by scancode analysis.
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.
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.
Fixes#10319
Added pin description comments to Arduino header pins and LED4.
Added I2C alias names.
Removed Oscillator and DEBUG pin definitions.
Use USBTX and USBRX for serial communications back to PC. Do not use STDIO_UART_TX and STDIO_UART_RX
For NUCLEO_F401RE, NUCLEO_F411RE, NUCLEO_F303RE, and DISCO_L475VG_IOT01A:
* Ensure the scatter files for the ARM toolchain use 2 region memory model.
The scatter files changes affects the following boards:
* NUCLEO_F401RE, STEVAL_3DP001V1 (stm32f401xe.sct)
* NUCLEO_F411RE, MTS_MDOT_F411RE, MTS_DRAGONFLY_F411RE, MTB_MTS_DRAGONFLY, SAKURAIO_EVB_01 (stm32f411re.sct)
* NUCLEO_F303RE, NUCLEO_F303ZE (stm32f303xe.sct)
* DISCO_L475VG_IOT01A, MTB_STM_L475 (stm32l475xx.sct)
* Remove the TOOLCHAIN_ARM_MICRO directories.
* Remove release_version as not necessary and as the targets can also run
Mbed OS 6.
* Remove uARM support for all FAMILY_STM32 targets.
