Rounding up to a multiple of 4 should be done using the ALIGN
macro. As a bonus, this also makes the generated code smaller.
In GetIocFacts(), sz is assigned to a few lines below without being
read in the meantime, so it is ok that it doesn't end up with the same
value as facts->FWImageSize.

ALIGN is certainly more readable to me.
