- Default "mbed_rom_size" in targets.json is then "0xCA000" (808K)

To optimize FLASH size, **stm32wb5x_BLE_HCILayer_fw.bin** is supported for MBED-OS use case
- As explained in Release_Notes.html, this FW is flashed at @ 0x080E0000
- Then "mbed_rom_size" can be updated to "0xE0000" (896K)
- As explained in Release_Notes.html, this FW is flashed at @ 0x080E1000 for versions 1.12.0 and 1.12.1 and at @ 0x080E0000 for older versions
- Then "mbed_rom_size" can be updated to "0xE1000" (900K) or "0xE0000" (896K)

```
"target_overrides": {
"NUCLEO_WB55RG": {
"target.mbed_rom_size": "0xE0000"
"target.mbed_rom_size": "0xE1000"
