Hm, mainly a clean compilation. Without this define I can not enable the flat 
device tree handling. LMB is quite new in U-Boot (PowerPC) and there are some 
dependencies to the FDT support. That force to enable even this feature on 
MicroBlaze too. I want to avoid a deep intrusion into the code.

Hm, could you pleace consult the PowerPC folks? I think LMB is used to 
transfer system memory map from U-Boot to Linux kernel in a common way 
(similar like on x86 PC from BIOS to kernel), or not? Any comments?
