[U-Boot] Incorrect CONFIG_SYS_MONITOR_LEN on MPC85xx boards

Hi, Kumar

I don't see any immediate problem with current FSL definitions
except they are confusing.

I think my proposal will not work on platforms like MPC8572,
MPC8536, and P2020DS where  TEXT_BASE is defined as
0xeff80000 instead of 0xfff80000. Can you please  explain the
reason why TEXT_BASE defined differently for these boards.

Thanks.

Felix.

I don't think there's some bug
