Well no, there is always an option to take the file,
"cat" all the files together to a single file,
which will result in the patches beeing applied in the correct order.

Less ugly than adding 94 patches and listing them in the recipe...

By "Manual", I mean:

do_apply_at91_exp_patch () {
     cd    ${S}
     for    f in `ls ../${PV}-at91-exp.4/*.patch` ; do
         cat $f    | patch -p1
     done
}

Why would that be a problem?

To me, maintaining this is much less work than maintaining a
SRC_URI statement.

Obviously, it would be better if the build system
had a defined order when applying patches from a file
containing multiple patches.
