- problem with basic clocking due to bad calculation of the PLPRCR
register's multiplication factor
- couldn't access the board's NVRAM due to incorrect initialization
order of chip selects; the Boot ROM's CS0 was overiding the setup
of the NVRAM.
- initialization of BR and OR memory controller registers was not
compliant with the MBX860 Users Manual
- board level configuration and status register # 2's mapping was
defined in the wrong bit order. This was resulting in a incorrect
error message about NVRAM battery failure.
