I thought you could include the hunk modifying sdram_ddr2_size in this 
patch too and make it a separate clean up to reduce the size of the 
Coccinelle patch making that easier to review but it's OK either way. 
Thanks for doing this clean up.

Regards,

Yes, I could do that, but since I got R-bys already, I opted for
minimizing change.

Thanks!
