            - add new attributes - packed, weak, forcedinline, align

- target.json - contains targets definitions

- ST - L1XX - Cube update to 1.5

     - SPI clock selection fix (clock from APB domain)

     - L0 -  baudrate init fix

     - L1 - Cube update v1.5

     - F3 - baudrate init fix, 3 targets CAN support

     - F4 - Cube update v1.12.0, 3 targets CAN support

     - L4XX - Cube update v1.5.1

     - F0 - update Cube to v1.5.0

     - L4 - 2 targets (L476RG/VG) CAN support
