No, 2nd, secondary and xloader are parts of the bootloader.
Flashing them can brick the device, should something go wrong, since
they provide the tablet-side interface to the pc-side flasher program.

In general one shouldn't care too much about the bootloader, since it
does basic board-specific initialisation, such as pad muxing.
