Following
Merge pull request #4063 from LMESTM/17q2_L4_bootloader
the NUCLEO_L476RG binairies could not boot anymore.
The change done in #4063 was derived from work on NUCLEO_L429ZI target
which supports uvisor. The VECTORS defintiion is introduced as part of
uvisor support and requires further changes in ld file which were missing.
As uvisor is not considered yet, we remove VECTORS for now and will
introduce only when needed.
Note that this could have side effects on the application as it would
not be aware that data has been missed. This may be later solved by
adding an error management parameter to the Serial API in mbed.
The advantage is that the serial link can work again.
1. Add startup code and linker script for IAR and
GCC_ARM compilers.
2. Enable IAR and GCC_ARM compilers in targets.json.

Based on lwip_ethernetif.c skeleton file,
use init, receive and transfer
functionality of SMSC9220 Ethernet driver
for the lightweight IP stack.
Receive mechanism is interrupt driven.
HW buffer sizes:
Tx = 4608 bytes (MTU)
Rx = 10560 bytes

- Creates new target in targets.json
- Creates device specific files under ARM_SSG/CM3DS_MPS2 directory
- Driver layer files under CM3DS_MPS2 are based on Beid target
- Device specific files under CM3DS_MPS2/device are based on CMSIS_5 and Beetle

Remove HAL_Init and related code from SystemInit and move it to
mbed_sdk_init. The function SystemInit is called early in the boot
sequence before RAM is initialized or the VTOR is setup, so it should
not be used to perform the HAL initialization.
This fixes crashes due the vector table being used before it has been
relocated.
* Make memory sections configurable in linker files
* Dynamically determine vector location in flash for NVIC relocation
* Advertise bootloader support in targets.json
Define CMSIS_VECTAB_VIRTUAL for the M0 targets which have a
corresponding driver. The only M0 target missing this is the LPC4330_M0
which is not part of the 2 or 5 release.
Restore cmsis_nvic (cmsis_nvic.c and cmsis_nvic.h) files for the
implementations which use a mechanism other than the VTOR to set
interrupts. These are vendor specific and were done for M0 devices
which do not have a VTOR.
Note - There were two cmsis_nvic files which did not use the VTOR that
which not restored in this patch. This is because these targets were
not M0 devices and could use the new unified implementation instead.
These files are:
targets\TARGET_ARM_SSG\TARGET_MPS2\TARGET_MPS2_M0P\device\cmsis_nvic.c
targets\TARGET_ONSEMI\TARGET_NCS36510\device\cmsis_nvic.c
Note - cmsis_nvic.c and cmsis_nvic.h were initial removed in
(and restored from) the commit:
b97ffe8fdc -
"CMSIS5: Replace target defined NVIC_Set/GetVector with CMSIS implementation"
When using ARM Compiler 5, the RTX config hard-coded the heap and stack
sizes to specific values. This prevented the RTX HAL from dynamically
allocating unused memory as heap space.
Specifically, the HEAP_START define prevents this logic in RTX_CM_lib.h
from activating. The rest of the defines are also set in that header,
and should be removed from here.
* Using PinName as bitfield doesn't work without warnings, since NC
needs all 32 bits to be represented.
* lp_ticker should not be freed when interrupt is disabled, since this
will kill the timebase.
