Patches as attachments are not really welcome on this list -- and as I 
said, patches which are not submissions for mainline inclusion should be 
avoided too.

Note that your patches have the added weirdness that many, if not all 
files in your patch have undergone attribute changes, with an addition 
of the "execute" flag that should never be set in a source code file. I 
suspect you are working on a Windows machine?

Also, then changes that are in your patch are strange: I can only see an 
addition in boards.cfg, based on what is there for B2, but nothing else. 
Is your board supposed to be so similar to B2 that le U-Boot baseline 
needs no change in the source code? But then, why would it need a change 
in boards.cfg?

Also, you should refrain from describing problems with "does not work" 
or "nothing happens". Clearly state what you do, how you do it, and then 
what you expect and do no get, or conversively, what happens that you 
did not expect.

Here for instance (assuming the code you're building is actually assumed 
to work with your board, which I cannot check), what exactly "does not 
happen"? What does the debugger tell you of the execution of the code? 
Does it go through the board_init_f calls sequence? Does it relocate? 
Does it enter the RAM execution stage?

I suggest you browse the mailing list archives for patch sets meant to 
add support for a new board and see how they are done and compare with 
what you did.
