I read this such that Lattice Semiconductor did the porting to U-Boot,
but is this correct?  I though you did that?  In that case you
probably want to write something like:

	Porting to U-Boot:

	(C) Copyright 2010
	Stefano Babic, DENX Software Engineering, sbabic at denx.de.

	Lattice ispVME Embedded code to load Lattice's FPGA:

	Copyright 2009 Lattice Semiconductor Corp.

or so?

Best regards,

Wolfgang Denk

Any time things appear to be going better, you have overlooked  some-
thing.
