* OpenBLT: linker file: use last 16 bytes of ram for shared area
This area is used for communication between FW and OpenBLT.
* OpenBLT: startup: invalidate only DFU breadcumb from startup code
Same location (but different seed) is used for shared param's

If 0x01 is stored in shared param idx=0, then stay in OpenBLT forever.
* Jump to OpenBLT: store proper shared param when OpenBLT is requested
TODO: calculate and store CRC too!
* OpenBLT: move shared_params to start of RAM
* Bootloader: Allocate 16 bytes at start of RAM for bootloader shared area
* OpenBLT: shared_params: reuse same .c and .h file for main application
* OpenBLT: shared_params: enable CRC check
* OpenBLT: no need to manualy set breadcumb before reset
