Moved UART6 into a separate unit:
UART6 connects internal devices. As a first step the existing code sections have been moved into a new unit. As well the code of the external GNSS sensor has been copied into this unit as starting point for the further development. Later the internal part can be integrated into the common uart (code cleanup).

| 32 1kB each header | |
| 33 with predive header at beginning | |
| 34 and postdive header with 0x400 HEADER2OFFSET | |
| 35 4kB (one erase) has two dives with 4 headers total | |
| 36 total of 512 kB (with 256 header ids (8 bit)) | |
| 37 Size is 280 Byte (as of 25.Nov. 2014) | |
| 38 | |
| 39 [..] Output to PC / UART is postdive header | |
| 40 | |
| 41 [..] Block Protection Lock-Down is to erase logbook only | |
| 42 | |
| 43 [..] Timing (see page 137 of LOGBOOK_V3_S25FS-S_00-271247.pdf | |
| 44 bulk erase is 2 minutes typ., 6 minutes max. | |
