I see two problems here.  First, this is a generic issue (any
legacy-style U-Boot image that we load should be verified).  Second, we
need to make this behavior configurable as as-is this overflows one
board (omapl138_lcdk) and I expect would be problematic for many more
boards when we make it done more commonly.
