1. Add Bus Bluster config/usage details
2. The Raspberry Pi 3 allows to enable JTAG on the GPIO via the
enable_jtag_gpio=1 flag in the config.txt, which is more prefarable.
Switch to this method
3. Add physical memory map
4. Change information about usage of Sequitur labs OpenOCD fork to
the uptsteam OpenOCD, as it already has ARMv8 support

was specified in a dhcp/bootp server configuration.
Renamed serverip var, which now is used for nfsboot target to avoid
updating of this value by DHCP/BOOTP clients and just to use our
pre-defined static value.
