[U-Boot] start.s file

[Deepak Gopalakrishnan]

Hi everyone...
In the quest of finding the code for relocation i have reached the start.s 
file present in u-boot-1.1.6\cpu\mpc83xx\ folder. Even its in assembly 
language (i dont know assembly language beyond movlw) i tried to 
understand that using the descriptions of the commands given in this site:
http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.aixassem/doc/alangref/mfmsr.htm
but im not able to proceed much. Is there any better way to understand 
this. 

thanks & regards,
Deepak Gopalakrishnan
