I talked to man from the hardkernel, and he said that there is no 
restrictions about adding BL1/BL2/TZSW as a binary blob to the Mainline 
U-Boot. So I think, in this case it should be provided also with those 
patches. Then we have a complete board setup.

To Hyungwon,
There is a size limit for each patch (100KiB), so if you would like to 
add such binary blob, you should add it using this site:
http://www.denx.de/wiki/attach/U-Boot/TooBigPatches
after a registration.
