PR 822/bsps
* console/console.c, startup/bspstart.c, startup/imbx8xx.c,
startup/mmutlbtab.c, startup/start.S, vectors/vectors_init.c:
Currently the MBX8xx BSP does not boot, because some logical errors
are in the startup code. Additionally, the mpc8xx shared clock driver
does not support the clocking scheme of some of the board variants,
which are clocked from a 32768Hz (!) external crystal.
