[PATCH][PPC32] MPC834x BCSR_SIZE too small for use in a BAT

[Randy Vinson]

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.
