Oddly enough, I originally called it ROUND_UP. But then I saw these lines
in include/common.h

#define ALIGN(x,a)              __ALIGN_MASK((x),(typeof(x))(a)-1)
#define __ALIGN_MASK(x,mask)    (((x)+(mask))&~(mask))

So, I deleted my definition of ROUND_UP and used ALIGN. But imximage.c
did not automatically include common.h. Instead of trying to include
common.h and all the files it pulled in, I added the ALIGN definition.
