Why do you think that this is a problem? What is you problem exactly, meaning 
what is not working? 

I just checked the top-of-git-tree version and also did this cmp.b. The first 
difference is noted at "1109744c d smc_mac_addr" (from System.map). This data 
is updated with the env variable ethaddr upon startup. So this seems 
perfectly reasonable.

Please try the omap5912osk version from top-of-git. I just updated it's 
support and it works here fine.

I have to admit, I don't know which board version we have installed.

Best regards,
