In both cases, that just affects the size of the file, but does not
affect the totalsize field in the fdt header.

Wrt. binman, just as I was somewhat misled by the short mkimage -h
output into thinking that this already worked as I expected, binman's
fit,align documentation can also be read that way - and the
_implementation_ certainly currently unconditionally translates a
fit,align property into a -B argument to mkimage. So if we don't want
mkimage to support a -B by itself, binman documentation and code would
probably need another patch to reject that as well.
