Greetings,
The value of BCSR_SIZE (32K) in arch/ppc/platforms/83xx/mpc834x_sys.h
is too small for a BAT (min 128K). The size is used in an
io_block_mapping call to map the Board Control and Status Registers.
Since there are no current dependencies on the result of the
io_block_mapping call, it was removed as a solution to the problem
rather than increasing the value of BCSR_SIZE. If access to the BCSR
block is needed, it can easily be mapped via ioremap at the point of use.
